Abstract
This report summarizes the environmental and personnel External Dosimetry Program, commonly
known as the Thermoluminescent Dosimetry (TLD) Program. The data were collected in the offsite
environs of the NTS between 1975 and 1998. The program has been under the auspices of the U.S.
EPA, External Dosimetry Laboratory in Las Vegas, Nevada, since January of 1971. Prior to that
time external dosimetry was performed by the Public Health Service (PHS) under an Interagency
Agreement (IAG) with the Atomic Energy Commission (AEC) from 1957 through 1965 using Du
Pont type 555 film badges. In 1966, film was gradually replaced with EG&G Model TLD-12 bulb
type dosimeters. Soon after (January 1971) its inception in December 1970, the EPA assumed the
responsibility, through an IAG with the Department of Energy (DOE) for the External Dosimetry
Program. From 1971 through June 1975, gamma-ray exposures at all monitored locations were
determined from TLD-12 bulb readings. From July 1975 to 1986, the averages were based upon
Harshaw model 2271-G2 (TLD-200) readings. From 1986 to 1999, Panasonic model UD-814
dosimeters were used for fixed environmental locations and Panasonic model UD-802 dosimeters
for personnel gamma radiation exposure monitoring. Fixed environmental annual averages ranged
from 0.17 mSv to 2.4 mSv, as shown in Appendix C. Personnel TLD results are shown in Appendix
D.
This summary represents information compiled from previously published annual and semi-annual
PHS and EPA reports. For a complete description of sampling strategies and activities during

Introduction
Background
External Dosimetry was performed by the
Public Health Service (PHS) under
Interagency Agreement (IAG) with the
Atomic Energy Commission (AEC) from
1957 through 1965 using film badges. The
film badges used for the fixed environmental
locations as well as for monitored personnel
consisted of Du Pont type 555 film. This film
had an accuracy of ± 50% in the 0.2 to 1.0
mSv range and ± 10% in the 1.0 to 20 mSv
range (SWRHL 70). Starting in 1966, film
was gradually replaced by Thermolummescent
Dosimeters (TLDs) because TLDs had greater
sensitivity and better precision. Reynolds
Electrical Engineering Company, Inc.
(REECO) processed the film and TLDs until
EPA was established in December of 1970.
Beginning January of 1971, EPA was
responsible for external dosimetry in the
offsite environs of the Nevada TestSite (NTS)
under an IAG with the Department of Energy
(DOE). From 1971 through June 1975, all
monitored locations contained three EG&G
Model TLD-12 bulb type dosimeters
consisting of CaF2:Dy. From 1975 to 1986,
Harshaw TLD-200 dosimeters were used.
These were mounted in a window of Teflon
plastic attached to a small aluminum card
under an energy compensation shield of 1.2
mrn thick cadmium. Three dosimeters were
placed one meter above the ground in a plastic
'birdcage' mounted on a metal stand
(OFFSITE 79). Froml987 to the present,
EPA used Panasonic UD-802s for personnel
dosimeters and UD-814s for fixed
environmental dosimeters.
Due to a moratorium on underground nuclear
testing that began in 1992, the scope of the
offsite TLD program was re-evaluated and the
number of fixed environmental locations and
the number of participating personnel were
subsequently reduced.
The NTS was established on about 3,500 km2
of the Nellis Air Force Bombing and Gunnery
Range in southern Nevada and was initially
used to conduct atmospheric tests.
Underground nuclear testing began in 1964.
Only three major accidental releases have
occurred since then [Pike (1964), Pin Stripe
(1966), and Baneberry (1970)]. Several other
tests were conducted that released
radioactivity detectable offsite. From 1962
through 1968, five earth cratering nuclear tests
were conducted as part of the Plowshare
Program. . Of these, Sedan, Cabriolet,
Schooner, and Palanquin released radio-
activity detectable off the NTS (BLACK 86).
Currently, low-level radioactive and mixed
waste disposal and storage facilities for
defense waste are operated on the NTS.
Restricted access, extended wind transport
speeds, and the remote location of the NTS
and adjacent U.S. Air Force land afford
protection to offsite inhabitants surrounding
the NTS (BLACK 96).
In the absence of nuclear testing, ambient
gamma radiation rates naturally differ among
locations since rates vary with altitude
(cosmic radiation) and with radioactivity in
the soil (terrestrial radiation). Ambient
gamma radiation will also vary slightly at a
location due to changes in weather patterns
and other factors.
Offsite fixed environmental TLD locations
surrounding the NTS were selected to detect
and monitor trends in total ambient gamma
radiation levels and in response to stakeholder
concerns. Residents in communities near the
NTS continued to express concerns about
radiation exposure due to previous, current
and proposed activities at the NTS. Use of
TLDs offsite was an effective method of
addressing these concerns.
-------
There is a difference between fixed
environmental dosimeter exposure levels and
personnel dosimeter exposure levels worn in
the same city or town due to the fact that
"background" ambient gamma radiation levels
vary significantly even within a city or town
due to shielding of personnel in buildings
where they work and live.
Design
Since 1987 the EPA TLD program has
utilized the Panasonic Model UD-802 TLD
for personnel monitoring and the UD-814
TLD for environmental monitoring. Each
dosimeter is read using the Panasonic Model
UD-710A automatic dosimeter reader.
The UD-802 TLD incorporates two elements
of Li2B4O7:Cu and two elements of CaSO4:Tm
phosphors. The phosphors are behind
approximately 17,300,300, and 1000 mg/cm2
of attenuation, respectively. With the use of
different phosphors and filtrations, a dose
algorithm can be applied to ratios of the
different element responses. This process
defined the radiation type and energy and pro-
vides a mechanism for assessing an absorbed
dose equivalent.
Environmental monitoring was accomplished
using the UD-814 TLD, which was made up
of one element of Li2B4O7:Cu and three
elements of CaSO4:Tm. The CaSO4:Tm
elements were shielded by approximately
1000 mg/cm2. An average of the corrected
values for elements two through four gave the
total exposure for each TLD. Two UD-814
TLDs were deployed at each station per moni-
toring period. These TLDs were placed in
infra red, heat sealed pouches in custom made
plastic holders, that could accommodate up to
four TLDs, on a metal stand one meter above
the ground.
In general terms, TLDs operate by trapping
electrons at an elevated energy state. After the
collection period, each TLD element is heated.
When heat is applied to the phosphor, the
trapped electrons are released and the energy
differences between the initial energies of the
electrons and the energies at the elevated state
are given off in the form of photons. These
photons are then collected by a photomultip-
lier tube. The number of photons emitted, and
the resulting electrical signal, is proportional
to the initial deposited energy.
Quality Assurance/Quality Control
TLDs were sent to a National Institute of
Standards and Technology (NIST) laboratory
for necessary irradiations to assure acceptable
quality to establish and check the algorithm.
Panasonic UD-802 dosimeters exposed by the
NIST laboratory were used to calibrate the
TLD readers and to verify TLD reader
linearity. A TLD irradiator manufactured by
Williston-Elin (WE), housing a nominal 1.8
Ci 137Cs source, was used in house by R&IE to
provide automated irradiations of the TLDs.
The WE irradiator data were plotted on a
control chart Control dosimeters of the same
type as field dosimeters (UD-802 or UD-814)
were exposed and read together with the field
dosimeters. This provided daily on-line pro-
cess quality control checks in the form of
irradiated controls.
• For each read-out three irradiated control
TLDs were included which were exposed
to a nominal 200 mR. After the irradiated
controls were read, the ratio of recorded
exposure to delivered exposure was
calculated and recorded for each of the
four elements of the dosimeter. This ratio
was applied to all raw element readings
from field and unirradiated control dosim-
eters to automatically compensate for
reader variations.
-------
Prior to being placed in service, element
correction factors were applied to all
dosimeters. Whenever a dosimeter was
read, the mean of the three most recent
correction factor determinations was
applied to each element to compensate for
normal variability (caused primarily by the
TLD manufacturing process) in individual
dosimeter response.
In addition to irradiated control
dosimeters, each group of TLDs was
accompanied by three unirradiated control
dosimeters during deployment and during
return. These unirradiated controls were
evaluated at the dosimetry laboratory to
ensure that the TLDs did not receive any
excess dose while either in transit or
storage. The exposure received while
either in storage or transit was typically
negligible and thus was not subtracted.
The assessment of TLD data quality was
based on the assumption that exposures
measured at fixed locations remain
substantially constant over extended
periods of time. A number of factors
combine to affect the certainty of
measurements. The total uncertainty of
the reported exposures is a combination of
random and systematic components. The
random component is primarily the
statistical uncertainty in the reading and
response of the TLD elements themselves.
Based on repeated known exposures, this
random uncertainty for the calcium sulfate
elements used to determine exposure to
fixed environmental stations was
estimated to be approximately ± 3 to 5%.
There were also several systematic
components of exposure uncertainty,
including energy-directional response,
fading, calibration, and exposures received
while in storage. These uncertainties were
estimated according to established
statistical methods for propagation of
errors.
• There are two accrediting bodies for
external dosimetry, the National Voluntary
Laboratory Accreditation Program
((NVLAP) and the Department of Energy
Laboaratory Accreditation Program
(DOELAP). Accuracy and reproducibility
of TLD processing of personnel
dosimeters have been evaluated via the
DOELAP and most recently by the
NVLAP. These processes concluded that
procedures and practices utilized by the
EPA R&ffi-LV TLD Laboratory comply
with standards published by the Depart-
ment of Energy. Evaluations included
three rounds of blind performance testing
over the range of 50 mrem to 500 rem and
comprehensive onsite assessments by
DOELAP and later by NVLAP site
assessors.
Data Management
During 1997, the TLD. data base resided on a
Digital Equipment Corporation Micro VAX II
directly connected to two Panasonic TLD
readers. Samples were tracked using field
data cards and an issue data base tracking
system incorporated into the reader control
software. Two major software packages were
utilized by the TLD network. The first, a
proprietary package written and supported by
International Science Associates (ISA),
controlled the TLD readers, tracked dosimeter
performance, completed necessary
calculations to determine absorbed dose
equivalent, performed automated QA/QC
functions, and generated raw data files and re-
ports. The second software package, locally
developed, maintained privacy act
information, identification data, generated
reports in a number of predefined formats, and
provided archival storage of TLD results.
Since the ISA software was not year 2000
compliant, and since the company went out of
business, R&IE purchased a PC-based
software system. In 1998, the new PC based
-------
software was implemented, validated, and the
result generation mechanism was verified and
performance tested through NIST and the
NVLAP performance testing program.
Accreditation was granted, and is current
through December 1999.
Offsite Radiological TLD Results
For Fixed Environmental Locations
There were 38 off site fixed environmental
locations monitored with TLDs in 1998. Total
annual exposure for 1998 ranged from 54 mR
(0.54mSv) per year at Las Vegas, Nevada, to
66 mR (1.7 mSv) per year at Queen City
Summit, Nevada, with a mean annual
exposure of 100 mR (1 mSv) per year for all
operating locations. All results are shown in
the table entitled Gamma Monitoring Results
for Offsite Personnel -1998, in Appendix D.
These results are consistent with those for
previous years, within statistical variability
associated with background ambient gamma
radiation levels.
Most of the variability in the monitoring data
is real spatial variation, reflecting different
background levels at different locations.
Overall spatial patterns of highs and lows
remain constant from year to year. Most
variability in the annual mean values is due to
bias.
The background pattern remains essentially
constant with all of the fixed environmental
locations tending to increase or decrease
together in any given year. Measurement
precision was acceptable. Precision during
1986-1997 was significantly less than during
the preceding ten years (due to a change in
manufacturer), but was adequate for
monitoring purposes. (ENG 98)
TLD Results for Personnel
From 1957 through 1966 personnel radiation
exposures was monitored using Du Pont film
badges. TLDs were gradually phased in
during 1966. This report covers only results
from TLDs; however, from 1964
through!970, radiation exposures in the off-
site environment were well below accepted
radiation guidelines recommended by the
Federal Radiation Council and standards
related to the AEC testing programs. Since
then none of the offsite residents received a
significant exposure. For more detailed
information regarding exposures during these
periods refer to the reference section that
follows (SWRHL 70).
Personnel exposures exceeded background
levels occasionally throughout the period
covered. Occupational exposures, incorrect
storage or handling of the TLD, e.g., storing a
TLD near a radiation source, medical
exposures during x-ray, and taking the TLD to
higher background areas were some examples
of such exposures. For example, in 1981, six
resident dosimeters exhibited exposures in
excess of background. These exposures were
attributed to higher background levels in the
residence than at the associated fixed
environmental location or to occupational
exposure as with resident number 49. The
average dose equivalents of the offsite
residents were generally lower than their
associated background fixed environmental
locations due to the shielding provided by
their bodies and by their homes or places of
work. Resident number 49 and resident
number 52 net exposures originated
occupationally from 1982 through 1986. In
1984, twelve dosimeters worn by residents
exhibited exposures in excess of background.
-------
These exposures were attributed to higher
background levels in the residence than at the
associated reference background location
(community monitoring location) or to
occupational exposure (as with resident
numbers 45,49,52 and 57) (OFFSUE 95).
Beginning in CY 1989, results for personnel
TLDs were reported in the average dose
equivalent rate for the year without subtracting
reference background. Associated reference
backgrounds were reported next to the annual
average for the respective individuals. In
1991, the reference backgrounds were no
longer reported; however, comparisons can be
made by referring to the associated, fixed
environmental location for the same year.
From 1991 through 1998, percent
completeness was included as a quality
assurance measure.
Eighteen offsite residents, acting as
Community Technical Liaison Program
(CTLP) managers, were issued TLDs to
monitor their annual dose equivalent in 1998.
CTLP station managers were usually science
teachers living in the community where the
radiation monitoring platforms were set up to
make radiation results available to the local
residents. The station contained high volume
air samplers, barometric pressure, temperature
and humidity sensors, wind speed and
direction instruments, Pressurized Ion
Chambers (PICs), that also measured ambient
gamma radiation in real time with a display,
and two fixed environmental TLDs. Annual
whole body dose equivalents ranged from a
low of 64 mrem (0.64 mSv) to a high of 124
mrem (1.2 mSv) with a mean of 88 mrem
(0.88 mSv) for all monitored personnel during
1998. A summary of the results is shown in
the table entitled "Gamma Monitoring Results
for Offsite Personnel - 1998" in Appendix D.
These results were similar to those for
previous years.

(LD Calculations)
Determination of LD:
Accomplished upon the addition of a new
dosimeter type to the program. Once
completed, this test is not normally repeated.
Two methods are acceptable for accomplishing
the task.
Method #1: At least 10 dosimeters for
irradiation per category, plus 10 dosimeters for
background evaluation, for each dosimeter
design, are selected from the routine
processed pool of dosimeters. The dosimeters
are placed in an unshielded environment for a
time sufficient to obtain an unirradiated
background signal typical for routine processed
dosimeters. At least 10 dosimeters are
irradiated for each category to a dose
significantly greater (e.g., 500 mrem) than the
estimated lower limit of detectability. Both the
irradiated and unirradiated dosimeters are
processed and evaluated. The following
quantities are calculated:

The dosimeter readings are processed through
the standard dose algorithms without truncation
or distortion (i.e., readings are not rounded to
zero). If a background is subtracted, negative
values are retained for the calculation of S0.
The'algorithms for the calculation of shallow
and/or deep dose equivalent are used to
calculate H0 and H1f depending on the category
test specifications. The lower limit of detection,
LD is then calculated as follows:
LD =

Where:
The t distribution for n -1 degrees of
freedom and a p value of 0.95.
H'0 = The average of the unirradiated
dosimeter values without subtracting a

Method #2: If NAVLAP performance testing
was completed within six months of this study,
then the values of B and S may be used to
calculate [1.75 X S/(1 + B)] which may be used
in place of tpS^H, in the above equation. Only
one set of unirradiated dosimeters is required
to determine L0 using this method.
-------
The above equation is based on the desire
to minimize both false negative and false
positive results. All values below the
detection threshold should be set to zero.
For example, tpS0 for p = 0.95 is an
estimate of the detection threshold allowing
5% false positive values. For the lower
limit of detection false negative values are
also minimized. For p = 0.95, the
probability of no more than 5% false
positive and false negative values provides
a lower limit of detection of:
Where:
S0 = The standard deviation of unirradiated
dosimeters.
tp,0 and tpD depend on the number of
dosimeters used to estimate S0 and
respectively.
t»
The above equation is an estimate of the
relationship:
LD = Kp o0 + Kp oD
Where:
o0 and OD = The true standard deviations.
Kp = The abscissa of the standard normal
distribution below which the total
relative area under the curve is P.
The o0 value is composed of the fluctuation of
the background (o0) and the fluctuation
inherent in the readout process. If 0,/H, is the
relative standard deviation at high doses, then
4 -
4\%\ ft
Method #1 is obtained. If tp,0 is not equal to tp,D,
the formula for L0 is not exact, but should be a
close approximation of the lower limit of
detectability.
Lower Limit of Detectability Determination -
Two methods of calculation are considered
acceptable and are detailed in this document. This
Determination uses the data obtained from a 6-
month fade study conducted with both UD-802
(personnel) and UD-814 (environmental)
dosimeters. In each case, the following calculation
is accomplished to determine lower limit of
