PREFACE
The Federal Radiation Council (FRC) was formed in 1959 to provide recommendations
to the President for Federal policy on radiation matters affecting health. The first Federal
radiation protection guidance was promulgated shortly thereafter, on May 13, 1960, and
applied to exposure of workers and the general population. Guidance dealing with
protection from radioactive fallout from weapon tests, protection of underground uranium
miners, and protective action levels for use in emergencies followed during the next decade.
On December 2, 1970, the Council was abolished and its functions transferred to the newly
formed Environmental Protection Agency (EPA), through Reorganization Plan No. 3 of
1970. The most recent guidance, promulgated February 1, 1978, applied to radiation
protection in the diagnostic use of x rays in medicine.
In 1974, EPA initiated a review of information on radiation exposure of workers as
part of the development of new recommendations for Federal radiation protection guidance
for occupational exposure. Two principal components of this review were a reevaluation of
risks from low levels of radiation by the National Academy of Sciences and an analysis of
occupational exposure of U.S. workers by EPA. In this report we continue this review
process by updating the calculation of concentrations of radioactivity in air and water that,
for average adult members of the population, correspond to the limiting doses
recommended under the 1960 Radiation Protection Guides for workers.
This updating is required because the metabolic and dosimetric models used to
calculate these quantities in 1960 no longer adequately reflect the present state of scientific
knowledge. This report makes use of the results of an extensive review and updating of
such models by the International Commission on Radiological Protection (ICRP)
published during the period 1979 to 1981. We have calculated numerical values for the
concentrations of radioactivity in air and water (in conventional and SI units) that satisfy
the 1960 Federal Radiation Protection Guides and are consistent with these up-to-date
metabolic and dosimetric models. The term "Radioactivity Concentration Guide" (RCG),
recommended by the FRC in 1960 for these values, is used in this report rather than the
term "Maximum Permissible Concentration" now in more common use in the United
States. The FRC terminology reflects more accurately the radiation protection principle
that there is no single permissible or acceptable level of exposure without regard to the
reason for permitting the exposure and without every effort to maintain that exposure as
low as reasonably achievable.
These new RCGs are published to provide the radiation protection community up-to-
date values based on current knowledge of radionuclide transport and the distribution of
dose in the body, as well as to provide the basis for evaluating effects of future revisions in
the Radiation Protection Guides themselves. New recommendations for Federal radiation
protection guidance for occupational exposure were proposed by EPA in 1981 (46 FR
VII
-------
7836), and final recommendations are currently under consideration by Federal agencies.
We plan to revise this report when new recommendations are approved and would
appreciate being informed of any errors so that they can be corrected for future editions.

INTRODUCTION
Radiation protection programs for controlling occupational exposure are based on a
hierarchy of numerical limitations stemming from primary radiation protection guidance.
Current primary guidance for U.S. workers includes numerical guides for the annual
radiation dose equivalent to body organs which should not be exceeded except in special,
justified cases. To facilitate application of a protection system* in the workplace, derived
guides, in the form of radioactivity concentration guides for radionuclides in air and water,
are developed from the primary guides. These derived guides are developed in such a
manner that exposures at these levels would not be expected to result in radiation doses
which exceed the numerical values of the primary guides.
The primary radiation protection guidance now in force in the United States was
established by the President, acting on recommendations of the Federal Radiation Council
(FRC), in 1960 (FRC 1960). That guidance was strongly influenced by and was generally
consistent with contemporary recommendations of the International Commission on
Radiological Protection (ICRP) and the U.S. National Council on Radiation Protection
(NCRP). An important part of this guidance is concerned with protection against
radiation from radioactive materials taken into the body. The FRC did not present, as part
of its guidance, numerical values for derived guides; rather, it endorsed the values in use
by government agencies at that time. Those values were contained in Report No. 22 of the
NCRP (NCRP 1959), which was an abridgment of Publication 2 of the ICRP (ICRP
1959).
The ICRP has recently revised its radiation protection guidance for occupational
exposure through issuance of recommendations in the form of new primary guidance in
Publication 26 (ICRP 1977) and corresponding secondary and derived limits in Publication
30 (ICRP 1979a, 1980, 1981c). The dosimetric and metabolic models employed by the
ICRP to derive these quantities supersede those presented in Publication 2 and represent
the considerably advanced state of knowledge in radionuclide dosimetry, including
biological transport in humans, achieved in the last two decades. The general features of
current ICRP models are discussed in Appendix B.
The term "dosimetry" is used here to encompass the entire process for estimating,
through computational methods, the radiation energy deposited in organs and tissues of the
body due to exposure to a given concentration of radioactivity in air and water. In this
sense, dosimetric models comprise mathematical representations of physical, anatomical,
physiological, metabolic, and radiobiological processes governing the exposure-dose
'Paragraphs 144-152 of ICRP Publication 26 (ICRP 1977) discuss the hierarchy of
various types of standards comprising a radiation protection system.

relationship. Because the dose to organs and tissues of the body is not measured directly, it
must be inferred from measurements of radionuclide concentrations in air or water or
measurements (direct or indirect) of radionuclides in the body and application of
dosirnetric models.
This report presents revised values for the derived guides, that is, radioactivity
concentration guides (RCGs), based on the 1960 primary radiation protection guides
(RPGs) for occupational exposure (FRC 1960) and for underground uranium miners
(EPA 197la) using the updated dosimetric models developed to prepare ICRP Publication
30. Unlike the derived quantities presented in Publication 30, which are based on
limitation of the weighted sum of doses to all irradiated tissues, these RCGs are based on
the "critical organ" approach of the 1960 guidance, which was a single limit for the most
critically irradiated organ or tissue. The dosimetric relationships used by the ICRP were
taken from data files at the Oak Ridge National Laboratory as assembled during the
development of Publication 30. No new computations or reevaluations of these data were
undertaken. Thus, this report simply provides revised derived guides for the 1960 Federal
guidance which are consistent with current dosimetric relationships.
-------
RADIATION PROTECTION GUIDES
The conduct of radiation protection activities by Federal agencies is guided by
recommendations approved by the President as Federal radiation protection guidance.
Most of the Federal guidance now in effect for protection of workers was developed by the
former FRC and was promulgated on May 13, 1960 (FRC 1960). The FRC was abolished
and its functions transferred to the Administrator of the EPA on December 2, 1970.
Revised Federal guidance for workers in underground uranium mines, specific to radon
decay products, was recommended by the FRC (FRC 1969, 1970) and promulgated by
EPA (EPA 197la, 1971b).
The first Federal radiation protection guidance set forth two basic principles for
radiation protection:
1. There should not be any man-made radiation exposure without the expectation of
benefit resulting from such exposure.
2. Every effort should be made to maintain radiation doses as low as practicable.
These two concepts have continued to be the underlying principles guiding the radiation
protection activities of Federal agencies. In addition, Federal guidance recommends
numerical limits on exposure of workers and members of the general public. These are
designated RPGs and serve as the upper bounds for exposure under normal conditions,
within the above framework for radiation protection.
Primary guides
The upper bounds on exposure of workers specified by the RPGs are the primary
guides that are used here to generate derived guides for limiting concentration of
radioactivity in air and water. These primary guides are given below.
Primary Radiation Protection Guides
Type of exposure (condition) RPG
Whole body, active marrow,
gonads, or lens of eye (annual) 5 rem accumulated average
Skin or thyroid (annual) 30 rem
Bone (body burden) 0.1 /tg Ra-226 or
its biological equivalent
Other organs (annual) 15 rem
Radon decay products (annual) 4 WLM exposure to Rn-222
decay products
-------
Derived guides
Derived guides, in the form of RCGs, are numerical values for the average
concentration of radionuclides in air and water such that normal intake of air or water or
submersion in air for 50 years at these levels would result in the primary radiation
protection guides being met in the 50th year of exposure (corresponding to an occupational
lifetime). The RCGs now used in the United States are exemplified by the U.S. Nuclear
Regulatory Commission regulations in 10 CFR 20. Most of these values were
recommended in 1959 by the NCRP and ICRP (NCRP 1959, ICRP 1959) and were
derived using models with the above objectives.
Exposure rather than dose is used to specify the RPG for bone-seeking radionuclides
and the short-lived decay products of 222Rn, as shown in the RPG table.
For bone-seeking radionuclides, the procedure implemented in ICRP Publication 2
restricted the dose equivalent rate in bone to that associated with a skeletal burden of
0.1 Mg of 226Ra, namely, 30 rem/year to the 7 kg of bone tissue. The new dosimetric
system of ICRP Publication 30 replaces this approach by detailed calculations of the dose
equivalent in two sensitive tissues of the skeleton, the active marrow and endosteal tissue
lying within 10 urn of bone surfaces (ICRP 1968, 1977, 1979a). To estimate the dose
equivalent in these tissues, it is necessary to classify radionuclides according to whether
they are distributed in the volume or along the surfaces of bone. The dose equivalent rate
to the endosteal tissue of the skeleton resulting from a burden of 0.1 /tig 226Ra is
estimated as 50 rem/year. Thus, in calculating the derived guides presented here, the RPG
equivalence for radium is based on a 50-rem/year implied limit for the dose rate to
endosteal tissue. A guide for the active marrow does not need to be derived from the
radium burden, since FRC provided explicit guidance for this tissue.
Inhalation of short-lived radon decay products results in a highly nonuniform
irradiation of respiratory tissues. The critical tissue is assumed to be composed of the basal
cells of the bronchial epithelium. The RPG for the control of exposure to radon progeny in
the workplace is based on epidemiological studies of uranium miners. The current guide
constrains the annual exposure to the short-lived radon decay products (daughters) of
222Rn to 4 working level months (WLM) (EPA 1971a, 1971b). One working level (WL) is
defined as any combination of short-lived radon decay products in 1 L of air that will
result in the ultimate emission of alpha particles with a total energy of 1.3 x 105 MeV.
The inhalation of radon decay products at a concentration of 1 WL for 170 h
(approximately one working month) is defined as an exposure of 1 WLM. Although the
RPG for underground miners was developed for exposure to the short-lived daughter
products of 222Rn, for completeness, we have extended use of the working level concept to
220Rn.
-------
RADIOACTIVITY CONCENTRATION GUIDES
Dose equivalent bases for the RCGs
To establish the RCGs, we first express the primary RPGs in terms of annual dose
equivalent for the various organs or tissues T of the body considered in the dosimetry
system of ICRP Publication 30. The annual dose equivalent guides are given below.
Annual Dose Equivalents for the RPGs
Organ/tissue Annual Dose (rem)
Whole body, active marrow,
gonads, and lens of eye 5
Thyroid and skin 30
Endosteal tissue
of skeleton 50
Other organs 15
These annual dose guides are those explicitly or implicitly recommended by the FRC in
1960. Note that the value assigned to the endosteal tissue of the skeleton is consistent with
the FRC recommendations of a "biological equivalence" with 0.1 ^ig of 226Ra. The Federal
guidance for radon decay products is treated below.
Calculation of the RCGs
In the supplements to ICRP Publication 30 (ICRP 1979b, 198la, 1982a, 1982b),
relationships between exposure or intake of various radionuclides and dose are tabulated
for Reference Man (ICRP 1975). The relationships for radionuclides taken into the body
are based on the committed dose equivalent per unit intake. The committed dose
equivalent, H50tT, represents the total dose equivalent to organ or tissue T over the 50-year
period following a unit intake of a radionuclide. It can be shown that #50,7 for an
instantaneous unit intake of any radionuclide is numerically equal to the annual dose
equivalent in the 50th year of continuous annual intakes of a unit activity. Thus, the
numerical values of #50,7- contained in the supplements to ICRP Publication 30 can be
used to estimate the annual rate at which a radionuclide could be continuously taken into
the body and not exceed the annual dose equivalent guides (RPGs) in the 50th year.
For radionuclides that are not metabolized by the body (such as radioisotopes of argon,
krypton, and xenon), submersion in an airborne concentration of the radionuclide results in
the irradiation of body tissue from radiation incident upon the body. The doses from
-------
inhalation of radioactive decay products of these elements are negligible in comparison to
the submersion dose. However, for the decay products of radon, the situation is just the
opposite. Here the dose for submersion is negligible relative to the dose from inhalation of
the decay products. The decay products of radon are discussed as follows. The dose
equivalent rate, HT, in tissue T per unit concentration for submersion exposures is
presented in the supplements to ICRP Publication 30. These values can be used in
conjunction with the annual dose equivalent guides (RPGs) to derive corresponding RCGs.
Internal Emitters: The critical organ, C, is defined as that organ of the body for which
the ratio between the committed dose equivalent per unit intake, H^T, and the RPG? is a
maximum. The critical organ determined for each radionuclide is dependent on whether
the radionuclide is inhaled or ingested and the chemical form of the radionuclide. The
concentration of a radionuclide in air or water which would result in an annual dose
equivalent corresponding to the RPG for the critical organ in the 50th year of continuous
intake is defined as
1
RCGni =

2.4 x 109 #so,c

where
2.4 x 109 is the volume, in cubic centimeters, of air inhaled by Reference Man in a
working year,
2.8 x 105 is the volume, in cubic centimeters, of water ingested by Reference Man in
a working year,
RPGC is the radiation protection guide (limit on the annual dose equivalent) for
critical organ C,
HSO, c is the committed dose equivalent for the critical organ C per unit activity
inhaled or ingested by Reference Man.
Numerical values of the RCGs for air and water are given in Appendix A, Tables 1 and 2.
In Appendix C, the classification of chemical compounds for lung clearance and
fractional absorption from the gastrointestinal (GI) tract are presented as recommended in
ICRP Publication 30. Additional information presented in Appendix C includes the
committed dose equivalent per unit intake for the critical organ and the limiting annual
intake and body burden. This body burden is the total activity present in the body after
50 years of continued intake at the limiting annual intake. The relationships of these
quantities to the RCGs are discussed further in Appendix C.
-------
Submersion: Dose equivalent rates, HT, in tissue T of the body from a unit
concentration of airborne radionuclides are given in the supplements to ICRP Publication
30. The critical organ for this exposure mode is the body organ for which the ratio of the
time integral of the dose equivalent rate over one working year (2000 h) per unit
concentration, Hc, to the RPGT is a maximum. The RCG for this exposure is
RPGC
= _ _
submersion TJ
The RCGs for submersion and the numerical values of the dose equivalent rate per unit
airborne concentration for the critical organ are shown in Appendix A, Table 3.
Radon decay products
The RPG for protection against inhalation of 222Rn decay products is expressed in
WLM, that is, in terms of exposure to decay products rather than dose. Since this guide is
the product of a concentration in air (WL) and duration of exposure, a concentration,
expressed in WL, that is analogous to the other RCGs can be directly calculated without
use of dosimetric models. While these concepts were developed for the prompt decay
products of 222Rn, they are also appropriate for 220Rn. [In the case of 220Rn, however, the
first decay product (216Po, T\/i = 0.15 s) decays so rapidly that it is omitted from the
calculation of WL exposure.] We have therefore also calculated an RCG expressed in WL
for 220Rn. These are the only two radionuclides for which the RCGs are based on exposure
to decay products that are produced prior to entry of the parent radionuclide into the
body.
The ICRP recently reviewed the epidemiological and dosimetric data for the two radon
isotopes of concern in uranium mining, namely, 222Rn and 220Rn, and concluded that the
risk from inhalation of the short-lived decay products of 220Rn was about one-third that
associated with 222Rn decay products (ICRP 1981b). The ICRP's recommended exposure
guidance for 222Rn is in close agreement with the current Federal guide (4 WLM).
Although a specific Federal guide has not been given for the decay products of 220Rn, the
ICRP's recommendation provides a basis for establishing a value equivalent with the
current Federal guide for 222Rn; this value is about 12 WLM. The derived RCGs for the
short-lived decay products of radon isotopes are given as follows.
RCGs for Radon Decay Products
Radon isotope WL
Rn-222 f/3
Rn-220 1
These RCG values correspond to annual exposures of 4 and 12 WLM for the decay
products of 222Rn and 220Rn, respectively.
-------
Chemical toxicity and biological capacity for intake
The RCGs given in this report are based solely on the radiation doses received by
organs and tissues of the body and do not reflect consideration of chemical toxicity or the
amount of material a worker could reasonably ingest or inhale. For some nuclides of very
low specific activity, the mass associated with the annual intake may imply an amount
greater than it is reasonable to expect a worker to inhale or ingest in any one year. As an
example, the annual intake of 0.4 jtCi of 115In (lung clearance class D) would correspond
to a mass of 650 kg. In other instances, the chemical effects of some materials, for
example, certain compounds of uranium, may present a greater risk than effects from
irradiation of body tissue. The chemical toxicity of contaminants in the workplace should
be examined as part of an industrial hygiene program, and the recommendations of the
American Conference of Governmental Industrial Hygienists (ACGIH) should be
consulted for additional guidance in limiting the airborne concentration of chemical
substances in the workplace (ACGIH 1980).
Principal assumptions and considerations
The computational procedures and models used to calculate the dosimetric values have
been outlined in Appendix B of this report. However, the reader is encouraged to also
become familiar with the details and assumptions presented in ICRP Publication 30
(ICRP 1979a). The following are the principal assumptions and factors used in the
calculations:
a. The RCGs are computed for occupational exposure of a worker for 40 h per week
and 50 weeks per year.
b. A worker ingests water at the rate of 1.1 L per 8-h working day.
c. A worker breathes at the rate of 20 L/min.
d. The activity median aerodynamic diameter (AMAD) of airborne particulate forms of
radionuclides is 1 j«n. RCGs for other AMAD values can be computed from information in
the Supplements to ICRP Publication 30.
e. The quality factor, Q, for alpha radiations is 20.
f. The modifying factor, N, in the definition of dose equivalent is taken as 1 in all
calculations.
g. The dose from submersion in an airborne concentration of inert radioactive material
and noble gas radioisotopes includes consideration of body shielding of organs. The dose
from beta particles and electrons is evaluated at a depth of 70 /urn for skin and at a depth
of 3 mm for the lens of the eye. The distribution in energy of the photons incident on the
body, including bremsstrahlung, is considered; however, the radiations emitted by any
radioactive decay product are not considered.
h. In most cases, the concentration limit for submersion in a radioactive semi-infinite
cloud is based on irradiation of the body and does not include consideration of any
absorbed gas within the body or the inhalation of any radioactive decay products.
-------
Exceptions are elemental tritium and 37Ar, for which the dose from activity in the lungs
limits their concentration in air.
i. Retention of material in body organs is generally represented by a multi-exponential
function. Material deposited in organs after its introduction into body fluids is assumed to
be eliminated from the organs without redeposition in other body organs.
j. For radionuclides that yield radioactive decay products, the calculations assume that
only the parent nuclide enters the body, although the calculated dose equivalent in the
50th year includes the contribution from the ingrowth of decay products over the period
following intake. For this reason, the ratio of the annual dose equivalent for the RPGs to
the estimated body burden for continuous exposure at the RCG can only provide a rough
indication of the ratio of dose equivalent in any year to the measured body burden in that
year.
k. The RCGs take into account the estimated time-dependent distribution of activity
within the entire body. Even in cases where no radioactive decay products are associated
with the radionuclide inhaled or ingested, the ratio of the annual dose equivalent for the
RPGs to the estimated body burden for continuous exposure at the RCG can only provide
a rough indication of the ratio of annual dose equivalent in any year based on a measured
body burden in that year.
1. No consideration is given to potential chemical toxicity; the RCGs reported here are
based solely on radiation protection considerations.
Many other factors may affect the actual doses received by workers as opposed to these
calculated here for Reference Man. Physiological differences, as well as differences in
habits, age, sex, and other factors, can influence the uptake and retention of radionuclides
by individuals. The use of the guides presented here for other exposure situations, such as
accidental exposures or exposures of the general public, requires careful consideration.
-------
THE EFFECT OF REVISED DOSIMETRIC MODELS ON THE RCGs
A comparison of the revised RCGs presented in Appendix A, Tables 1-3 with those of
ICRP Publications 2 and 6 (ICRP 1959, 1964) reveals that in some instances substantial
changes in the numerical values have been introduced by the new data and revised
dosimetric models. As the chemical form of inhaled or ingested materials is now
characterized in a manner different from that of Publications 2 and 6, the appropriateness
of comparisons, in some instances, is questionable. Furthermore, identification of specific
items contributing to the change in numerical values is complicated by the many factors in
the calculations. Despite these difficulties, the old and revised values were compared to
identify those radionuclides whose RCGs have been changed substantially. In these cases
the major item or items contributing to the change in numerical values are noted.
Before discussing the comparisons, it is instructive to examine the magnitude of
possible changes introduced by revisions in the dosimetric models.
Major revisions in dosimetric models
In Appendix B the current dosimetry models are reviewed with particular emphasis on
the advances since the issuance of ICRP Publication 2 (ICRP 1959). The advances in
models that most influence dosimetric relationships are the model for translocation of
inhaled material from the lung and the dosimetry model for tissues of the skeleton.
Model for Retention of Inhaled Material in the Lung
In Publication 2 a simple model of the lung was used to define the translocation of
material into the body after inhalation. Seventy-five percent of the inhaled activity was
assumed to be deposited in the lung; the remaining 25% was exhaled. For soluble materials
the fractional transfer to blood of the inhaled activity was taken to be 0.25 + 0.50 f\. The
factor 0.25 represents the fraction of inhaled activity considered to be transferred directly
to blood, while the fraction 0.50 was assumed to be cleared upward from the lung and
swallowed, thereupon entering the GI tract. Of the activity swallowed, the fraction f\ is
assumed to be absorbed from the GI tract to blood. The dose equivalent to the lung from
the temporary residence of soluble materials was not considered in Publication 2. On the
other hand, the RCGs for insoluble materials were based only on the dose equivalent to the
lung or segments of the GI tract, since the transfer of insoluble materials to blood was not
considered. A clearance halftime from the lung of 120 days was used for all insoluble
radionuclides except plutonium and thorium, for which halftimes of 1 and 4 years,
respectively, were used. An initial deposited fraction, 0.12, of the inhaled insoluble activity
was assumed to be retained in the lung for these halftimes.
11
-------
The dosimetric analysis of Publication 30 (ICRP 1979a) employs a more refined lung
model (ICRP 1966), wherein deposition in regions of the lung is defined in terms of the
AM AD of the aerosol and the clearance of deposited activity is defined in terms of three
clearance classes D, W, and Y. Furthermore, clearance kinetics is modeled to account for
loss of material through radioactive decay. For a long-lived radionuclide, the fractional
transfer of inhaled activity to blood can be expressed in a manner analogous to the
Publication 2 lung model as shown.

respectively.
^AMAD = 1 fj.m; radioactive decay neglected.
The implications of the changes in modeling the transfer of inhaled material to blood
can be inferred by examining the table. The classes D, W, and Y correspond to clearance
times for the pulmonary region of the lung on the order of days, weeks, and years,
respectively. For compounds with /i values less than 10~2, the model of Publication 30
results in a higher transfer of activity to blood, relative to the lung model of
Publication 2, for class D compounds (0.48 vs 0.25) and a lower transfer (0.12 vs 0.25)
for class W compounds. If/j approaches 1, the two models predict similar transfers, the
only difference being in the initial deposition estimate, which is 63% for an AMAD of
1 urn in the Publication 30 model compared with 75% in the Publication 2 model.
As noted earlier, the dose equivalent to the lung was considered in Publication 2 for
insoluble compounds only. The dose equivalent is proportional to the time integral of the
activity in the lung. If the inhaled radionuclide is long lived, that is, long relative to the
biological clearance halftime, the fraction, 0.12, of the inhaled activity assumed to be
retained in the lung results in the following tabulated values of the time integral.

to the integral) in the lung predicted by the lung model of Publication 30 is about four
times higher than the value predicted from the model of Publication 2. Furthermore, for
radionuclides other than thorium and plutonium, a factor of 10 is indicated for class Y
compounds. For compounds now assigned to clearance class W, the assumption of the
insoluble form in the model of Publication 2 results in an overestimation by factors of
about 20, 5, and 2 for thorium, plutonium, and other radionuclides, respectively. It should
be noted that in this discussion the loss of activity by radioactive decay has not been
considered; therefore, the above differences are maximum values.
In summary, the revised modeling of the translocation and retention of inhaled
materials can affect the RCGs through an increased transfer of inhaled material to blood
for class D compounds relative to the soluble forms considered in Publication 2.
Furthermore, the dose equivalent to the lung as estimated in Publication 2 for insoluble
forms is overstated by factors between 2 and 20 if the material is a class W compound and
understated by factors of 4 to 10 if it is a class Y nonthorium compound.
Dosimetric Model for Bone Seekers
The dosimetric model for bone-seeking radionuclides has also been modified
substantially in ICRP Publication 30. This model provides for calculations of the dose
equivalent to endosteal tissue adjacent to bone surfaces and the dose equivalent to the
active marrow. In the model of Publication 2, formulated in terms of a comparison with
226Ra, the dose equivalent was averaged over the entire mass of the marrow-free skeleton
bone (7 kg). In the following discussion of these two models, the same activity is assumed
to be present in the entire skeleton so that the magnitude of the changes introduced by
methods for computing the specific effective energy (SEE) for target tissues of the
skeleton can be examined (dose equivalent is directly proportional to SEE). The discussion
will be limited to particulate radiation, that is, alpha and beta radiations.
The specific effective energy deposited in the skeleton per unit energy (E) emitted in
bone, SEE/E, for the dosimetric model of Publication 2 is given by
SEE /E =
m
13
-------
where
TV is the modifying factor,
Q the quality factor, and
m is the mass of bone.
The value of N in the model of Publication 2 was 1 or 5, depending on whether or not the
spatial distribution of the radionuclide was considered to be similar to 226Ra. The results
are given in the following table of specific effective energy per unit emitted energy
(SEE/E).

In Publication 30 the energy deposition is averaged over a 10-^m layer of soft tissue
(endosteal tissue) adjacent to the surfaces of bone. In estimating the energy deposition in
this region, consideration must be given to whether the radionuclide is distributed on the
surface or within the volume of bone. The specific effective energy for the endosteal tissue
per unit emitted energy, SEE/E, is given as
FcBQ AF(BS *~ W + FTBQ AF(BS - TB)
m
where
FCB and FTB denote the fraction of the activity in the skeleton residing within or on
the surfaces of cortical and trabecular bone, respectively,
Q is the radiation quality factor,
AF(BS *- CB) and AF(BS •«- TB) represent the fractions of the energy emitted
within or on the surfaces of cortical and trabecular bone, respectively, that are
absorbed by the endosteal tissue,
m is the mass of the endosteal layer adjacent to the bone surfaces, taken as 120 g.
Values for the parameters of the above formulation are contained in ICRP
Publication 30 (see Chapter 5 of ICRP 1979a). Using these values the SEE deposited in
the endosteal tissues per unit emitted energy are as follows:
14
-------
Publication 30 Bone Dosimetry

Emitter in volume 1.4 x 10~4
Emitter on surface
E < 0.2 MeV 4.2 x 10"3
E > 0.2 MeV 3.3 x 10~4
Note that in this table, the quality factor Q for alpha radiation is taken to be 20 rather
than the value of 10 used in Publication 2, and the modifying factor, N, is 1 in all cases.
The major impact of the new bone dosimetry model occurs for alpha and low-energy
beta emitters, in particular those radionuclides which are surface seekers. The SEE (and
thus dose equivalent) for the endosteal tissues from surface seekers is 60 times higher than
the value for bone in Publication 2 for isotopes of radium and 12 times higher for other
alpha-emitting surface seekers. Radium is actually a volume seeker, and thus the factor of
60 would only apply to short-lived radium isotopes, for example, 224Ra. For isotopes of
radium distributed throughout bone volume, the dose equivalent in the endosteal region is
1.6 times higher than that for bone. If the alpha emitter is volume distributed, the dose
equivalent for endosteal tissue is three times lower than that for bone. Thus, the revised
bone dosimetry model can be expected to affect substantially the RCGs for alpha and
low-energy beta emitters distributed on the surface of bone.
Changes in the RCGs
To compare the revised RCGs with those of ICRP Publications 2 and 6, several
conventions were established here in an attempt to compare values for similar chemical
forms. These conventions are not based on an in-depth consideration of the translocation of
inhaled or ingested compounds in the body. Such a consideration is, of course, not possible
within the soluble-insoluble classification scheme of ICRP Publications 2 and 6. The
following conventions were followed for inhalation exposure:
a. The old RCGs for inhalation of the soluble forms, given as maximum permissible
concentrations (MFCs) in Publications 2 and 6, were compared with the revised
RCGs of Table 1 for compounds of lung clearance class D. If no class D compounds
of the radionuclide were given in Table 1, the comparison was made with the revised
RCG for class W compounds. It was considered inappropriate to compare soluble and
class Y compounds.
b. The old RCGs for the insoluble form, given as MFCs in Publications 2 and 6, were
compared with the revised RCGs of Table 1 for class Y compounds. If no class Y
compounds for a radionuclide were indicated in Table 1, then the comparison was
15
-------
made with the RCG for class W compounds unless that class W compound had
already been used for comparison with the soluble compounds.
In the case of ingestion exposure, the conventions were as follows:
a. If all compounds of the radionuclide were assigned a single /i value in Table 2, the
revised RCG was compared to the corresponding old RCG for the soluble form, given
as MFCs in ICRP Publications 2 and 6.
b. If compounds of the radionuclide were assigned two f\ values in Table 2, then the
revised RCG for compounds with the higher /\ value were compared with the old
RCG for soluble compounds of Publications 2 and 6, and those of the lower /i were
compared with the old RCG for the insoluble form.
Inhalation Exposure
The comparison of old and revised RCGs for inhalation is shown in the histogram of
Figure 1. In about 80% of the comparisons, the values differ by less than a factor of 4, and
in one-half of the comparisons, the values differ by less than a factor of 2.
Nuclides with revised RCGs that are substantially different from the old values, that is,
at least 32 times more restrictive (i.e., 32 x revised RCG < old RCG) or at least 16 times
less restrictive (i.e., revised RCG > 16 x old RCG), are shown below.

-------
The change in the RCG for 115In (half-life of 5.1 x 1015 years) is of more academic
than practical interest since it would appear impossible to maintain an airborne
concentration corresponding to the RCG for this low-specific-activity radionuclide. The
metabolic model for indium given in ICRP Publication 30 assumes that 30% of the indium
entering the transfer compartment (body fluids) is translocated to the red marrow (the
critical organ in the revised RCG), where it is retained with an infinite halftime. The
metabolic model of Publication 2 assumed that 4% of the indium entering blood was
translocated to the kidney (the critical organ), where it was retained with a biological
halftime of 60 days. The change in the metabolic model is the dominant feature of the new
dosimetric analysis contributing to the change in the RCG. The other radioisotopes of
indium are sufficiently short lived that the assumption of infinite retention does not
substantially affect their RCG.
The revised RCG for 241Pu (class Y) is about 100 times more restrictive than the old
RCG for the insoluble form. Plutonium-241 is the only plutonium isotope where the critical
organ for inhalation of class Y compounds is not the lung. The dosimetric analysis of
Publication 2 assumed that insoluble plutonium cleared from the lung with a halftime of
one year and that the transfer to systemic organs need not be considered. The dominant
contribution to the dose equivalent for 241Pu exposures is the alpha-emitting daughter
product 241Am. In Publication 2 the ratio of the 241Am daughter activity to that of the
parent in the lung, assuming the above noted retention halftime, was 7.1 x 10~4 (see
Table 5.a of Publication 2). The Task Group Lung Model, as employed in
Publication 30, indicates an activity ratio of 1.3 x 10~2 (see Supplement to ICRP
Publication 30, Part 1). However, the computational approach of Publication 30
considers the transfer of activity to blood and its uptake in systemic organs; this results in
the RCG being based on the dose equivalent to bone surfaces.
The more restrictive revised RCG for 93Zr is largely a result of the new metabolic
model, where the retention in bone is a factor of 8 higher than previously assumed. This,
coupled with an increased transfer to the skeleton of about 3 (increased clearance of class
D compounds to blood and increased deposition in the skeleton), largely accounts for the
noted change in the numerical value. Other radioisotopes of zirconium are sufficiently
short lived so that the revised skeletal retention does not substantially change their
numerical value.
The revised RCG for 244Am is more restrictive partly due to an apparent error in
Publication 6 regarding the half-life of this nuclide. The half-life of the metastable state
(244mAm, half-life of 26 min) was assigned to the ground state, whose half-life is now
considered to be 10.1 h. The metastable state, 244mAm, was not included in the tabulations
of Publication 6. Since the half-life, not biological clearance, of this americium isotope
governs the activity in the body, the error resulted in an underestimate of the activity of
the body by a factor of about 23. This factor largely accounts for the change in the value
for 244Am.
The revised RCG for class W compounds of 187Re is 40 times less restrictive than the
old RCG for insoluble forms of Publication 2. Rhenium-187, like 115In, is a low-specific-
activity radionuclide with a half-life of 5 x 1010 years. The retention of inhaled material in
the lung is similar (within a factor of 2) for insoluble and class W compounds. In
Publication 2 the effective beta energy was taken to be 0.012 MeV per disintegration.
18
-------
Newer nuclear decay data, as used in Publication 30, consider the average energy to be 6.6
x 10~4 MeV (ICRP 1983). Thus, the new information on the decay of 187Re is the
dominant source of the change in its RCG.
The metabolic model for sulfur presented in Publication 30 indicates a much more
rapid loss of sulfur from the body than assumed in Publication 2. The revised metabolic
model suggests that 80% of the sulfur introduced into body fluids is excreted promptly,
15% of the sulfur is retained with a halftime of 20 days, and the remaining 5% is assigned
a halftime of 2000 days. In the model of Publication 2, 0.13% of the sulfur entering blood
was transferred to the testis, the critical organ, where it was considered to be retained with
a halftime of 623 days. Because of the decreased deposition and retention of sulfur in the
body, the critical organ for the revised RCG is the lung.
In the computational model of Publication 2, a fraction of the inhaled activity of
soluble radionuclides was considered to be instantaneously transferred to systemic organs
with no consideration of radioactive decay during clearance from the lung and uptake in
systemic organs. The computational approach of Publication 30 accounts for radiological
decay during the course of clearance from the lung and uptake in tissues of the body.
Iodine entering the transfer compartment is considered to be translocated from this
compartment at a rate corresponding to a halftime of 0.25 days. The half-life of 134I
(52.6 min) is short compared to the rate of transfer from blood to the thyroid, and thus,
radiological decay reduces the uptake of 134I by the thyroid (about a factor of 8 relative to
Publication 2). Radiological decay during clearance from the lung also contributes to a
lower thyroid uptake of this radionuclide and, thus, a less restrictive RCG.
Ingestion Exposure
The comparison of old RCGs (MFCs of ICRP Publications 2 and 6) with the revised
RCGs in Appendix A, Table 2 for exposure by ingestion is shown in the histogram of
Figure 2. In about 80% of the comparisons, the values differ by a factor less than 4, and
55% of the comparisons differ by less than a factor of 2. The nuclides whose revised RCGs
are substantially changed are tabulated below.

19
-------
As in exposure by inhalation, the list of radionuclides whose revised values are more
restrictive is dominated by radionuclides for which bone surface (endosteal tissue) is the
critical organ. In addition, with the exception of 115In, all the radionuclides are considered
to be bone surface seekers, that is, to deposit on the surface of bone. Furthermore, the
revised metabolic model for these radionuclides includes an increased uptake from the GI
tract to blood, that is, the /i parameter.
The increased uptake from the GI tract to body fluids is the dominant factor in most
cases where revised RCGs are more restrictive. As discussed previously, the change in the
retention of 115In within the body also contributes to its RCG being more restrictive. Other
changes in the metabolic models for these radionuclides, generally involving an increased
fraction deposited in bone and a lower skeletal retention, do not contribute substantially to
changes in the numerical values of the RCGs. The revised dosimetric model, which
classifies bone seekers as surface and volume seekers, also contributes to the changes in
numerical values.
The revised RCGs for both 63Ni and 226Ra are less restrictive due to changes in their
metabolic models. Sixty-eight percent of the nickel entering the transfer compartment is
excreted, and 30% is distributed throughout the total body and retained with a 1200-day
biological halftime. The remaining 2% is transferred to the kidney, where it is retained
with a halftime of 0.2 days. Under this metabolic model with the lower uptake from the
GI tract, the critical organ is the lower large intestine. In the metabolic model of
Publication 2, one-half of the nickel which reached blood was assumed to be transferred to
bone, where it was retained with an 800-day biological halftime.
The higher (less restrictive) RCG for 226Ra is the result of the decreased retention of
radium in the skeleton as indicated by the alkaline-earth model of ICRP Publication 20
(ICRP 1973a). An effective halftime of 1.6 x 104 days was assumed in Publication 2.
From Table 36 of Publication 20, the time integral of the retention of 226Ra in the skeleton
indicated by the alkaline-earth metabolic model is 98.7 jtCi-day per microcurie entering
blood. The same time integral for the retention model of Publication 2, assuming one-tenth
the radium entering blood is transferred to the skeleton, is 970 pCi-day/nCi. Thus, the
major reason the revised RCG for 226Ra is less restrictive is the reduced retention indicated
in the alkaline-earth model. On the other hand, the change in the quality factor for alpha
radiation (now taken as 20 rather than 10), the slightly reduced absorption from the GI
tract, and the revised dosimetric model for bone seekers all contribute to a reduction in the
magnitude of the change from that caused by the change in retention.
Submersion Exposure
Only a limited number of comparisons are possible for submersion, since this exposure
mode is principally of concern for noble gas radionuclides. The radionuclide comparisons
possible between Publication 2 and the revised values of Table 3 are shown below.
For the most part, the revised RCGs are less restrictive due to the dosimetric model
taking into account the shielding of body organs from the overlying tissues. The revised
values for 3H and 37Ar are based on radionuclide content in the lung rather than on
external irradiation of body tissues. Both of these nuclides emit radiations that are too
weak to penetrate the outer skin layer. The other radionuclide for which the RCG has been

reduced substantially is 85Kr. Krypton-85 emits gamma radiation of rather low intensity,
and thus, the new value is based on the dose to skin. In addition, the old RCG for 85Kr of
Publication 2 was derived from a dosimetric model that assumed that beta particles of
energy greater than 0.1 MeV contributed to the whole body dose.
Summary
A comparison of the old RCGs endorsed in 1960 by the Federal Radiation Council
(FRC 1960) with the revised RCGs presented in this report indicates that in about 80% of
the cases, changes in the numerical values were not substantial, that is, less than a factor
of 4. However, some RCGs are altered substantially by the new metabolic and dosimetric
models, in particular, the lung and bone dosimetry models. Revisions in half-life, nuclear
decay data, uptake to body fluids, retention in lung and body tissues, and energy deposition
estimates also contributed to changes in the RCGs. Even if the RCG for a given
radionuclide has not been revised substantially, it should not be concluded that the
components of its dosimetric analysis have not changed.

"The lung clearance classes D, W, or Y correspond to
clearance halftimes from the pulmonary region of the lung on
the order of days, weeks, or years, respectively. Compounds
other than particulate forms are denoted by "*" and defined in
the first column; for example, see 11C. In such cases, an f,
value is not stated because these compounds enter body fluids
directly from the lung. See also the information in Table 4.
^The following abbreviations for organs and tissues are
noted:
BON SURF endosteal tissues within 10 »*m of bone surfaces
LLI WALL wall of the lower large intestine
R MARROW red (active) marrow
S WALL wall of the stomach
SI WALL wall of the small intestine
SOF TIS soft tissues

APPENDIX B
ADVANCES IN DOSIMETRIC MODELS FOR RADIONUCLIDE INTAKE
Dosimetry models are mathematical representations of the metabolic, anatomical,
physiological, and radiobiological processes that affect estimates of radiation dose to tissues
of the body. In this appendix the state of dosimetry modeling as represented in ICRP
Publication 30 (ICRP 1979a) is briefly reviewed with particular emphasis on advances
over the dosimetry system of ICRP Publication 2 (ICRP 1959). In recent years the
International System of Units (SI) has begun to replace the older conventional dosimetric
units (ICRU 1980). In the discussion below, the conventional units are used, and SI units
are given in parentheses.
Dosimetric quantities
The International Commission on Radiological Units and Measurements (ICRU) is the
recognized organization involved in selecting and defining radiation quantities and units.
The reader should consult ICRU Report 33 for authoritative definitions (ICRU 1980).
Absorbed Dose: The absorbed dose, D, is the quotient of de~ by dm, where de~ is the
mean energy imparted by ionizing radiation to matter of mass dm. Absorbed dose in an
organ of the body is generally estimated by averaging the energy imparted over the entire
mass of the organ. The special unit of absorbed dose is the rad (gray, Gy).
Dose Equivalent: For purposes of radiation protection, it is desirable to modify the
absorbed dose quantity to obtain a quantity that expresses on a common scale, for all types
of ionizing radiation, the effect to be inferred per unit dose. The dose equivalent, H, is the
product of D, Q, and N at the point of interest in tissue where D is absorbed dose, Q is the
quality factor, and N is the product of all other modifying factors:
H = DQN .
The special unit of dose equivalent is the rem (sievert, Sv).
Quality Factor: In past radiation protection recommendations by national and
international groups, the relative biological effectiveness, RBE, was used to modify the
absorbed dose. The resulting quantity was referred to as the RBE dose (ICRP 1959,
NCRP 1959). To avoid confusion, usage of RBE is now restricted to radiobiology. The
RBE of the radiation under study is defined as the ratio of the absorbed dose of a
reference radiation to the absorbed dose of the radiation under study that would produce
an equivalent radiobiological response. The term quality factor (denoted by Q) is now used
in radiation protection to modify absorbed dose to obtain dose equivalent and is
independent of the organ or tissue or of the biological endpoint under consideration. Values
73
-------
of the quality factor are given in ICRP Publication 21 (ICRP 1973b) as a continuous
function of the collision-stopping power of charged particles in water. Since the
uncertainties involved in estimating dose equivalent are large relative to the variation in
stopping power for a particular radiation, Q is usually assigned a constant value for each
particular type of radiation. The quality factors used in ICRP Publication 30 are
Q = 1 for beta particles, electrons, and all electromagnetic radiations,
Q = 10 for spontaneous fission neutrons and protons,
Q = 20 for alpha particles, recoil particles, and fission fragments.
In ICRP Publication 2, a quality factor (then called RBE) of 10 was recommended for
alpha radiation, and other modifying factors, N, had the value 1 or 5. The ICRP now
recommends that the product of all other modifying factors, N, should be taken as 1
(ICRP 1977).
Committed Dose Equivalent: For radiation exposures involving inhalation or ingestion
of radionuclides, it is useful to evaluate the total dose equivalent associated with the intake
over a working lifetime. The committed dose equivalent, HSO.T- is defined as the total dose
equivalent in tissue T for the 50-year period following the intake of the radionuclide, that
is, the 50-year integral of the time-dependent dose equivalent rate, HT. For radionuclides
retained briefly in the body, either as a result of a short physical half-life or rapid
biological elimination, the committed dose equivalent will be delivered within a relatively
short time following the intake. For long-lived radionuclides with tenacious retention in the
body, the dose equivalent rate will be nearly constant throughout the post-intake period so
that the committed dose equivalent will be experienced over the entire 50-year period.
Formulations for calculating dose equivalent
The basic formulations employed in the calculation of dose-equivalent are outlined
below as adopted from ICRP Publication 30. For a detailed discussion of the calculational
procedures and associated data, the reader is referred to that document (ICRP 1979a).
Internal Exposure: The committed dose equivalent in organ T due to inhalation or
ingestion of a radionuclide is given by
where
Us is the total number of nuclear transformations of the nuclide under consideration
occurring in source organ S over a period of 50 years per unit intake,
SEE(T <— 5) is the specific effective energy deposited per unit mass of target tissue
T per nuclear transformation in source organ S.
The summation is over all source organs S, that is, all organs where activity resides during
its sojourn in the body. The numerical value of the constant K depends on the units desired
74
-------
for HSO,T afld those specified for Us and SEE. In Publication 30, Us is expressed in nuclear
transformations per Bq, SEE in MeV/g-nuclear transformation, and K corresponds to 1.6
x 10~10 Sv-g/MeV, so that H50>Tis expressed in Sv/Bq.
The quantity SEE defines the energy imparted to tissue T due to radiations emitted in
source organ S. This factor embodies the relevant details of the radiations emitted in
nuclear transformations of the radionuclide, including their quality factor, as well as the
distribution of absorbed energy among body tissues.
The quantity Us represents the number of nuclear transformations per unit intake of a
radionuclide occurring in source organ S over a 50-year period. This quantity is
proportional to the total energy released in the source organ per unit intake. It is computed
as the integral of the time-dependent activity residing in the organ and thus reflects the
metabolism of the radionuclide in the body.
Submersion: Some radionuclides are not metabolized to an appreciable extent by the
body, and thus limits for their airborne concentration are based on irradiation of tissues
from radiations incident upon the body. The nuclides in this category primarily comprise
radioisotopes of the noble gas elements. The dose rate HT to tissue T per unit airborne
concentration in a semi-infinite cloud is computed as
where SEE(T •*— C) is the specific energy absorbed per gram of target tissue T per nuclear
transformation per m3 occurring in the cloud C (MeV-m3/g-nuclear transformation). If the
airborne concentration is expressed in Bq/m3 and the numerical constant K is 5.8 x 10~7,
the HT is expressed in the units Sv/h per Bq/m3.
Dosimetric models and parametric data
Dosimetric models and their supportive data have advanced considerably in the last two
decades. In this section the various components of the dosimetric analysis are reviewed
with particular emphasis on the advances since the issuance of ICRP Publication 2 (ICRP
1959).
a. Nuclear decay data. Knowledge of the radiations emitted during the nuclear
transformation process is essential to the computation of dose equivalent. Data describing
these radiations enter into consideration through the SEE factor defined above.
Considerable refinements in nuclear decay data have been made in the past 20 years
through both experimental and theoretical studies. Information as basic as the physical
half-life of a radionuclide has undergone considerable revision in some instances.
b. Reference Man. A well-defined characterization of man in terms of both anatomical
and physiological parameters is needed to establish concentration guides. The
recommendations of Publication 2 were based on Standard Man as defined in that
publication. The ICRP, noting the need for a more detailed representation, formed a Task
Group on Reference Man whose report, Publication 23 (ICRP 1975), provides the basic
anatomical and physiological data required for dosimetric evaluations.
75
-------
c. Inhalation model. The recommendations of ICRP Publication 2 were based on a
simple model for deposition of inhaled material which gave no consideration to the size of
particles making up the aerosol. In all cases, 75% of the inhaled activity was assumed to be
deposited in the lung. The physical-chemical nature of the aerosol, which determines its
clearance from the lung, was classified simply as "soluble" or "insoluble." Soluble materials
were considered to clear rapidly enough that the dose to the lung could be ignored in
deriving RCGs. On the other hand, insoluble materials were assumed not to be absorbed
by the body; thus, only the dose to lung and segments of the GI tract were considered in
deriving the RCGs for these materials.
The limitations of the inhalation model were soon recognized and the ICRP established
a Task Group on Lung Dynamics to formulate a more detailed model (ICRP 1966). The
detailed model, referred to as the Task Group Lung Model (TGLM), considers the
respiratory system to consist of a nasopharyngeal, tracheobronchial, and a pulmonary
region. The regions are interconnected with one another as well as with the blood, the GI
tract, and the lymphatic system. The fraction of the inhaled aerosol deposited in each
region is a function of the activity median aerodynamic diameter (AMAD) of the aerosol.
The aerosol is assigned to one of three classes to define its clearance from the lung. The
classes, denoted by D, W, and Y, correspond to clearance times for the pulmonary region
of the lung on the order of days, weeks, and years, respectively. The reader is referred to
the task group report (ICRP 1966) and subsequent ICRP publications (ICRP 1972,
1979a) for further details.
d. Gastrointestinal Tract. The tract is represented by a series of four segments, the
stomach, the small intestine, the upper large intestine, and the lower large intestine. In the
model presented in Publication 2, material was assumed to reside in the stomach for 1 h
and then move to the small intestine. Movement of material through the small and large
intestines was assumed to be continuous and linear. The dose to the wall of each intestine
segment was calculated at the entrance to the segment. In the dosimetric model for the GI
tract used in Publication 30, transit times through the segments were revised as
recommended by Eve (1966), and the masses of the wall and contents (and the transit
times) correspond to the values given in ICRP Publication 23 (ICRP 1975). Ingested
material is no longer classified as simply soluble or insoluble. The transport of material
through the tract is modeled with exponential clearance from the segments. The potential
absorption of material into body fluids, generally taken to occur within the small intestine,
is characterized by the numerical values for the fractional absorption from the tract (the f\
parameter). The dose to each segment of the tract is computed as an average over the
mass of the wall of that segment.
e. Metabolic models. Central to the development of dose estimates is information
characterizing the translocation of material from body fluids into organs of the body and
its retention in these organs. In Publication 2, radionuclides entering blood were taken to
be deposited instantaneously in organs, and retention in an organ was characterized by a
single biological halftime, that is, the time over which one-half the initial deposition would
be eliminated by biological processes. Even though it was known that this approximation
failed to represent the retention of many radionuclides, the approach was adopted for
calculational convenience. To provide an element of conservatism, the longest halftime of
an observed multi-exponential retention was assumed in the calculations. In the years
76
-------
following the issuance of Publication 2, considerable effort has been expended to refine the
understanding of metabolic processes through studies involving man and animals. Today
the distribution and retention of many of the radionuclides in the body are much better
defined than at the time Publication 2 was issued. For example, the metabolic model of the
alkaline-earth elements presented in ICRP Publication 20 (ICRP 1973a) is the most
sophisticated metabolic model used in radiation protection in that many processes
governing their metabolism are identified and contained in the model.
/ Estimation of Energy Deposition. The dose equivalent to organs of the body depends
on the energies and intensities of the various radiations emitted in nuclear transformations,
the distribution of the radionuclide among organs of the body, and the deposition of the
energy in organs and surrounding tissues. In Publication 2 the dose equivalent rate in an
organ was based only on the activity present in that organ; the contribution to the dose
from activity in nearby organs was not considered. The fraction of photon energy absorbed
in an organ was based on an assumed effective radius for the organ. With the advent of
high-speed computers and with increased knowledge of the physical processes governing
the interaction of radiation with matter, it has been possible to develop detailed
calculations of the energy deposition throughout the body. Such information has been
widely used within the nuclear medicine community for a number of years and has been
incorporated into ICRP Publication 30.
g. Bone Seekers. The skeletal burden of bone seekers in ICRP Publication 2 was based
on an equivalence with 0.1 ^g 226Ra. The biological equivalence was based on a
comparison of the effective energy deposited in the skeleton for the radionuclide in
question with that of 226Ra. For all nuclides that emit particulate radiation, other than
radium and its decay products, a modifying factor of N=5 was applied in computing the
effective energy. This was done because of lack of knowledge regarding the deposition
pattern within the skeleton and its relationship to the skeletal tissues at risk. This approach
avoided the complex dosimetry problems represented by the skeleton by substituting
experience with radium in man.
Following the issuance of ICRP Publication 2, considerable effort has been directed
toward the dosimetry of bone seekers. There is now general agreement that the
radiosensitive tissues of the skeleton are the hematopoietic stem cells of the active (red)
marrow and the osteogenic cells, particularly those on the endosteal surfaces of bone
(ICRP 1968). Developing blood cells are found in various stages of maturation within the
active marrow; hence, active marrow is of concern with respect to leukemia. The need to
limit the dose to this tissue was recognized in Publication 2 but was not implicitly treated
in developing the recommendations for bone-seeking radionuclides. The osteogenic cells are
the precursors of cells involved in the formation of new bone (osteoblasts) and the
resorption of bone (osteoclasts) and thus are of concern with respect to induction of bone
cancer. The location of the osteogenic cells in the skeleton is not well defined; for
dosimetric considerations, the ICRP has calculated the dose equivalent averaged over a
10-fj.m layer of soft tissue adjacent to the surface of bone (ICRP 1977). In calculating the
dose to these tissues, radionuclides must be classified according to their residence site in
the skeleton, that is, either volume or surface seekers. Therefore, it is now possible to
address the skeletal tissues of concern in a dosimetric analysis, so that the modifying factor
N now can be taken as 1.

-------
h. Submersion. In Publication 2 the total body dose (whole body) from nuclides not
significantly metabolized, generally noble gas radioelements, was used to limit their
airborne concentration. Photon radiation and beta particles of energy greater than
0.1 MeV were assumed to contribute to this dose quantity. In the case of low-energy beta
emitters, the airborne concentration was limited by the dose to the skin and no
consideration was given to a depth dose. The dosimetric analysis in Publication 30 for this
exposure mode considers the shielding of body organs due to the overlying tissues.
In this brief discussion the general features of the current computational approach of
radiation dosimetry have been outlined. We focused on the major features in current
dosimetric considerations within the context of Reference Man. Estimates of dose to
individuals who, through anatomical, metabolic, or other aspects, depart from this
characterization, may well be quite different. In the event of a significant intake by a
worker, efforts should be undertaken to determine the particular factors which govern the
dose to that individual worker.

APPENDIX C
SUPPORTIVE DATA AND INFORMATION
Tabulated in Table 4 of this report are data and information which are of a supportive
nature to the Radioactivity Concentration Guides (RCGs) presented in Appendix A,
Tables 1 and 2. Some of the terms used in Table 4 are defined below.
Nuclide/Half-life:
The radionuclide and its half-life are shown in the first column of the table.
The time units m, h, d, and y correspond to minutes, hours, days, and years,
respectively. The radionuclide designation follows conventional practice with
the symbol m denoting metastable state. In some instances, for example, 182Re,
the half-life needs to be referred to in establishing the unambiguous
identification of the radionuclide.
Lung Class,/i, and Compounds:
These data identify the characterization of the chemical form assumed in the
calculations. In the case of inhalation (abbreviated inh.), the lung clearance
class [D (days), W (weeks), or Y (years)] and the fractional uptake from the
small intestine to blood (/i) are shown as well as the identification of assigned
compounds. In the case of ingestion (abbreviated ing.), no lung clearance class
is shown. This information is an abstract of the metabolism discussion from
ICRP Publication 30 (ICRP 1979a, 1980, 1981c) and is presented only as a
general guide. The user should consult the more detailed discussion in ICRP
Publication 30 before making any decision on classification of compounds in
the workplace.
Annual Intake:
The limiting annual intake of the radionuclide in microcuries through
inhalation or ingestion that would result in a dose to the critical organ equal to
its RPG in the 50th year of continuous intake. Note that the numerical value is
dependent on the chemical form of the inhaled or ingested material.
Body Burden:
The total activity in microcuries present in the body, including the respiratory
and GI tracts, after 50 years of continuous intake at the limiting annual intake
by Reference Man. The numerical value depends on the exposure mode and the
chemical form of the material.
81
-------
% sys:
Denotes the percentage of the body burden that has been absorbed into body
fluids, the systemic burden, and thus excludes activity residing in the
respiratory or GI tract.
H
50-
The committed dose equivalent per unit intake for the critical organ identified
in Appendix A, Tables 1 and 2. Note that the numerical value also can be
interpreted as the annual dose equivalent after 50 years of continued annual
intake of unit activity, rem per /uCi/year.

GLOSSARY
Absorbed Dose (D): The quotient of de~ by dm, where de is the mean energy imparted by
ionizing radiation to matter of mass dm. The special SI unit of absorbed dose is the gray
(Gy); the conventional unit rad is still in use (1 rad = 0.01 Gy).
Absorbed Fraction: The fraction of energy emitted as a specific radiation type in a
specified region which is absorbed in a specified target tissue.
Activity Median Aerodynamic Diameter (AMAD): The diameter of a unit density sphere
with the same terminal settling velocity in air as that of the aerosol particle whose activity
is the median for the entire aerosol.
Annual Intake: The total activity of a radionuclide inhaled or ingested by a worker
(Reference Man) during a working year if concentrations in the work environment
correspond to the RCG.
Becquerel (Bq): The special name for the SI unit of activity, 1 Bq = 1 s~', which is
-2.7 x 10~n Ci.
Committed Dose Equivalent (H5()jT): The total dose equivalent averaged throughout tissue
T in the 50-year period following the intake of a radionuclide into the body.
Curie (Ci): The special name for the conventional unit of activity, 1 Ci = 3.7 x 1010 Bq.
Decay Products: A radionuclide or a series of radionuclides formed by the nuclear
transformation of another radionuclide, which in this context is referred to as the parent.
Dose Equivalent (H): The product of the absorbed dose (/)), the quality factor (Q), and
any other modifying factors (N). The SI special unit of dose equivalent is the sievert (Sv);
the conventional unit rem is still in use (1 rem = 0.01 Sv).
External Radiation: Irradiation of body tissues by radiations incident upon the body from
a source external to the body.
Internal Radiation: Irradiation of body tissues by radiation emitted from radionuclides
distributed within the body.
Ionizing Radiation: Any radiation displacing electrons from atoms or molecules, thereby
producing ions.
Lung Clearance Class (D, W, or Y): A classification scheme for inhaled material
according to its clearance halftime on the order of days, weeks, or years from the
pulmonary region of the lung.
Nuclear Transformation: The spontaneous transformation of one nuclide into a different
nuclide or into a different energy state of the same nuclide.
163
-------
Quality Factor (Q): The principal modifying factor that is employed in deriving dose
equivalent, H, from absorbed dose, D. The quality factor is chosen to be a smooth function
of the collision-stopping power of charged particles.
Radiation Protection Guide (RPG): This term refers to the radiation dose which should
not be exceeded without careful consideration of the reasons for doing so; every effort
should be made to encourage the maintenance of radiation doses as far below this guide as
practicable.
Radioactivity Concentration Guide (RCG): The concentration of a radionuclide in air or
water which is determined to result in organ doses equal to the Radiation Protection
Guide.
Rem: The conventional unit of dose equivalent. 1 rem = 0.01 joule per kilogram = 0.01
Sv.
Sievert (Sv): The special name for the SI unit of dose equivalent. 1 Sv = 1 joule per
kilogram =100 rem.
Source Tissue (S): Any tissue or organ of the body which contains a significant amount of
a radionuclide following intake of that radionuclide into the body.
Specific Effective Energy [SEE(T *- S)]: The energy (MeV), suitably modified for the
radiation quality factor, imparted per gram of a target tissue T as a consequence of the
emissions of radiations in the nuclear transformation of a radionuclide in source region S.
Target Tissue (T): Any tissue or organ of the body in which radiation is absorbed.
Working Level (WL): Any combination of short-lived radon decay products in 1 L of air
that will result in the ultimate emission of 1.3 x 105 MeV of potential alpha energy.
Working Level Month (WLM): An exposure of 1 WLM corresponds to the inhalation of
air with a concentration of radon decay products of 1 WL for 170 working hours
(1 working month).
