UNITED STATES ENVIRONMENTAL PROTECTION AGENCY
Office of Radiation Programs
-------
Environmental Radiation Data (ERD) is compiled and distributed
quarterly by the Office of Radiation Programs' Eastern Environmental
Radiation Facility (EERF), Montgomery, Alabama. Data from the
Environmental Radiation Ambient Monitoring System (ERAMS), and
similar networks operated by contributing States, Canada, Mexico, and
the Pan American Health Organization are reported in (ERD) when
available.
ERAMS was established in 1973 by the U. S. Environmental
Protection Agency's Office of Radiation Programs (ORP). The ERAMS is
comprised of nationwide sampling stations that provide air, surface,
and drinking water and milk samples from which environmental
radiation levels are derived. The major emphasis for ERAMS is toward
identifying trends in the accumulation of long-lived radionuclides in
t he envi ronment.
1. Sampling locations are selected to provide optimal
population coverage while functioning to monitor fallout from nuclear
devices and other forms of radioactive contamination of the
environment.
2. The radiation analyses performed on these samples include
gross alpha and gross beta levels, gamma analyses for fission
products and specific analyses for uranium, plutonium, strontium,
iodine, radium, krypton and tritium. This monitoring effort also
serves to provide ancillary information on releases into the
environment from stationary sources such as nuclear power reactors,
fuel fabrication and reprocessing plants and natural background
levels.

DATA - Reporting Rationale and Procedures
The intent of EPA's Office of Radiation Programs in establishing
the Environmental Radiation Ambient Monitoring System was to provide
continuous, accurate and usable environmental radiation data for the
public. Therefore, new data reporting procedures were developed to
allow better interpretation of the data. The most significant change
in this reporting procedure is that all specific radionuclide
analyses will be reported as the counting results indicate, whether
the nunber is negative, zero, or positive.
Reporting Rationale
Frequently, concentrations of a radionuclide in environmental
media are close to zero. When the actual concentration of a nuclide
is zero, the net counting results should statistically show a
distribution of negative and positive numbers about zero. This
occurs when the background count is subtracted from a sample which
has only background activity. Prior to July 1975, ERAMS data were
not reported numerically when the results were less than a specified
reporting level or minimum detectable level. The present reporting
procedure allows all the data to be reported and evaluated
statistically without an arbitrary cutoff of small or negative
numbers. This approach will facilitate estimates of bias in the
nuclide analyses and will allow better evaluation of distributions
and trends in environmental data.
When reviewing the data in this report, caution should be
exercised in the interpretation of individual negative values.
Obviously, a negative activity value does not have physical
significance. Such numbers, however, are significant when taken
together with other observations which indicate that the true value
of a distribution is near zero. Uhen an average of several
measurements produces a result less than zero, this indicates a
negative bias in the measurement procedure.
(1) Reported Values
Specific Analyses - All specific radionuclide analyses will
be reported as the counting results indicate, whether the nunber
is negative, zero, or positive. Numerical values given are as
of sample collection date.
Gross Analyses - The actual value of gross radioactivity
measurements will be reported, unless the value is below the
minimum detectable level (tlDL) at the 2 sigma confidence level,
then < minimum detectable level will be reported.
Ill
-------
11DL is defined as tbe 3 sigma error of the background. A
tabulation of MDL's is given in the following table.
(2) Reported Error Terns
Each reported value for specific analyses will be
accompanied by a counting error tern at the 2 sigra (95%)
confidence interval. Potassium concentrations are determined by
specific activity analyses. Error terms are therefore reported
as counting errors. At the very low levels characteristic of
most ERAMS measurements, counting error is the greatest
contributor to overall error.
(3) Significant Figures
All reported values will be rounded to no more than three
significant figures. The last significant figure will be
increased by one if the figure following is five or greater,
otherwise it is left unchanged.
(A) Reporting Levels
The reporting units, smallest increments for reporting, and
minimum detectable levels for each isotope are shown in table 1.
Smallest increments are sometimes considerably smaller than
minimum detectable amounts to avoid truncation errors in
averaging.
(5) Averages
Averages will be calculated along with appropriate error
terms in an annual summary and analysis of ERAMS data. In
calculating these averages, all values of individual data
including negative numbers will be utilized. Averages will not
be included in ERD quarterly reports.

ENVIRONMENTAL RADIATION
AMBIENT MONITORING SYSTEM (ERAMS)
SECTION I. Air Program
Airborne Particulates and Precipitation
Gross beta radioactivity measure-rents and certain specific
analyses are performed on air participates and precipitation samples
as indicator measurements in assessing the general (national) impact
of all contributing sources on environmental levels of radiation.
Airborne particulates are collected continuously at field
stations representing wide geographic coverage, including present and
potential sources of environmental radioactivity. Sampling sites are
located throughout the United States, Virgin Islands, and the Panama
Canal.
Filters (10-cm charcoal impregnated cellulose) from air samplers
are changed twice weekly and field measurements are made with a Oil
survey meter at 5 hours and 29 hours after collection to allow for
radon and thoron daughter product decay. Field estimates are
reported to appropriate EPA officials by telephone or mail depending
on the activity levels found.
The filters are sent to EERF for more sensitive analyses in a
low background beta counter. Canna scans are performed on all
filters showing laboratory gross beta counts greater than 1
pCi/m3. The lower gross beta values reported for laboratory
measurements are largely due to the decay of radionuclides which
occurred between the times of the field estimates and laboratory
measurements.
Precipitation samples are collected at the field stations where
air filters are collected. These samples are also sent to EERF where
they are composited monthly for tritium, gross beta activity
measurements and gamma scans.
These locations also correspond to airborne particulate and
drinking water sampling locations selected for plutonium analyses.
Plutonium-238, -239, and uranium-234, -235, and -238 analyses are
performed annually on precipitation samples collected during March -
May.
-------
Tables 2-4 present the monthly average ^ross beta
concentrations in airborne particulates for October - December 1981.
Tables 5-7 present the monthly average gross beta
concentration and any specific gamma concentrations for precipitation
samples for October - December 1981. A compilation of individual
measurements is available from the EPA, EERF, Montgomery, AL 36193.
The tritium in precipitation samples for October - December 1981
at the selected stations are shown in Table 8.

Plutonium and Uranium In Airborne Particulates
Environmental radiation levels of plutonium and uranium are
determined by the analyses of quarterly composite samples (air
filters) collected from the continuously operating airborne
particulate samplers. The number of continuously operating stations
is being increased from the original 22 will eventually number 67
when all equipment is operational.
Analyses of the composited filters consist of ashing, separating
by liquid ion exchange, and coprecipitation of the plutonium or
uranium.
Concentration of the specific isotopes of plutonium-238, -239,
and uranium-234, -235, and -238 are determined by alpha spectroscopy.
The volume of air analyzed normally ranges from 25,000 to 40,000 m^
for each quarterly composite.
Plutonium and uranium in airborne particulates data for July -
September 1981 "are shown for the 42 stations operating during this
period in Table 9.

Krypton-85
Krypton-85 is a long-lived noble gas with a half life of 10.8
years. It is released into the atmosphere by nuclear reactor
operations, fuel fabrication, fuel reprocessing, and nuclear
detonations. Krypton-85 also occurs naturally in minor quantities
primarily from the neutron capture of stable krypton-84 as well as
spontaneous fission and neutron-induced fission of uranium.
Monitoring of krypton-85 in the atmosphere has been conducted to
identify and establish baseline levels and long-term trends.
Krypton-85 analysis began in January 1973 with sample
collections and analyses being performed for 12 sampling locations.
These locations were selected to provide atmospheric coverage of the
United States with considerations being given to the proximity to
fuel reprocessing plants, nuclear reactors, and wide geographic
coverage.
Dry compressed air samples, collected at each location, are
purchased from commercial air suppliers semiannually and shipped to
the EERF where the krypton-85 is cryogenically separated and counted
in a liquid scintillation system.
Data for January - June 1976 were reported in ERD 8.

DATA - EPA
ERAMS
SECTION II. Water Program
The ERAMS water program provides ambient radiation data to
assess the effects of the nuclear power industry, the natural
radiation environment, and other nuclear sources on the nation's
rivers, streams and drinking water supplies.
Surface Water
Grab samples are taken quarterly at 58 stations located
downstream from operating or future nuclear facilities.
Surface water monitoring consists of tritium analyses quarterly
and gamma scans annually. Tritium is the primary radioactive
pollutant from nuclear power plants.
Tritium concentrations are determined by liquid scintillation
counting of distilled samples. Gamma scans are performed annually to
determine if there is a buildup of other contaminants.
Tritium concentrations for surface water samples for October -
December 1981 are given in Table 10.

Drinking Water
The drinking water program provides ambient radiation monitoring
relevant to the effects of the nuclear power industry, natural
environmental levels, and other pertinent sources. These data serve
to assess trends and anomalies in concentrations, and to compare with
standards set forth in the EPA "National Interim Primary Drinking
Water Regulations." These regulations provide for approval of
supplies when the combined radium-226 and radium-228 levels do not
exceed 5 pCi/1, when the gross alpha (excluding radon and uranium)
levels do not exceed 15 pCi/1, when tritium levels do not exceed
20,000 pCi/1, when the strontium-90 levels do not exceed 8 pCi/1, and
when the gross beta levels do not exceed 50 pCi/1.
Grab samples are taken at 78 sites which are either major
population centers or selected nuclear facility environs.
The analyses include (a) tritium on a quarterly basis (b) gross
alpha, gross beta, and strontium-90 on annual composites (gamma
analyses are performed if the gross beta activity is greater than 10
pCi/1; radium-226 analyses are performed if the gross alpha exceeds 2
pCi/1; and radium-228 analyses are performed if the radium-226
activity falls between 3 and 5 pCi/1) (c) specific iodine-131 is
performed on one quarterly sample per year for each station (d) an
annual composite for plutonium-238, -239, uranium-234, -235, -238, on
22 selected sampling locations corresponding to continuously
operating air particulate stations.
Tritium analyses are performed by scintillation counting of the
distilled samples, gross beta, and gross alpha by evaporating an
aliquot on stainless steel planchets for counting, and radium-226 by
the standard emanation technique. Strontium-90 is determined by beta
counting a strontium carbonate precipitate isolated by ion exchange.
The results of tritium in drinking water analyses for October
December 1981 are shown in Table 11.
All samples were taken as either a single grab sample or
composite samples taken over 12 to 14 days.
Radon-222 in Drinking Water
Radon-222 in drinking water has previously been considered a
source of radiation exposure primarily from an ingestion standpoint.
The Office of Radiation Programs (ORP) of the U.S. Environmental
Protection Agency (EPA) is investigating radon in water supplies to
evaluate the possibility that a major pathway from inhalation
exposure may exist in addition to the Ingestion pathway. As an inert
gas, radon is not chemically bound to the water and consequently can
be released during any operation that aerates or agitates water.
Depending upon the initial concentration of radon in water,
16
-------
significant quantities of radon could be released in a home or to the
general environment.
To determine the scope of this potential problem, a national
ground water sampling program has been initiated by the Eastern
Environmental Radiation Facility (EERF) to obtain data on radon
concentrations in water supplies throughout the country. Sampling
kits have been assembled by EERF and distributed to various state
health departments. The kit is designed so that state personnel can
collect samples from potable water supplies and ship them, without
loss of radon other than radioactive decay, to EERF for analysis.
The selection of water supplies to he sampled is handled by two
separate nethods. Method 1 in which each state collects samples from
all groundwater supplies serving at least 1000 people and Method 2 in
which the choice of sampling locations and the number of supplies to
be sampled is left to the discretion of the state programs. Each
state is asked to obtain a representative sampling of ground water
supplies within its boundaries. The extent of the sampling efforts
and how representative the data are for a given state is determined
primarily by the amount of time each state devotes to the program.
The concentrations of radon in water are determined at the EERF
by liquid scintillation counting. The limit of detection for this
technique using a 50-minute count and a 10-ml sample is 0.16 pCi or
16 pci/1.
The sampling kits are being provided to the various states on a
rotating schedule. This schedule is designed to cover the U.S.
within approximately two years. As data from each state are compiled
they will be published in ERD.
Summaries of the data from Indiana, North Carolina, New Mexico,
Pennsylvania and Wisconsin are shown in Tables 12 - 16.

SECTION III. External Gamma Ambient Monitoring Program
The external gamma monitoring program, which began in October
1978, provides a continuous measurement of ambient gamma exposure
rates, including cosmic, at selected sites throughout the continental
United States. Data from this program will be used to evaluate
fluctuations in natural background due to variations in environmental
conditions and to provide a means of monitoring any significant
increases in ambient gamma levels due to weapons fallout, reactor
operations, etc. Initially, the program will consist of
approximately 22 sites representing a wide geographic coverage
throughout the country. Hopefully, at some later date additional
sites will be added to the program. Although exposure measurements
at these few sites are not totally representative of nationwide
exposures, they will be indicative of national trends.
The monitoring program utilizes CaF2iMn thermo luminescent
dosimeters (TLD's). These dosimeters are commercially available
glass-bulb type dosimeters with energy compensating shields. A group
of four TLD's is located at each station or site. Dosimeters are
annealed by the station operator prior to positioning in the field.
The dosimeters are returned to EERF for readout on an approximate
one-month cycle. Several dosimeters are annealed by the station
operator as controls and returned with the exposed field dosimeters
to correct for any exposures accumulated during shipment.
Results from the period October 1981 through December 1981 are
shown in Table 17.

SECTION IV. Milk Program
Pasteurized Milk
This is a cooperative program of the EPA, ORP and the Dairy and
Lipid Products Branch, Milk Sanitation Section, Food and Drug
Administration. Milk is a reliable indicator of the general
populations intake of radionuclides since it is consumed by a large
segment of the population and contains several of the biologically
important contaminants resulting from environmental releases from
nuclear activities. A primary function of this program is to obtain
reliable monitoring data relative to current radionuclide
concentrations and determine any long-term trends.
Monthly samples are collected at 65 sampling sites with one or
more located in each state, Puerto Rico, and the Panama Canal. These
are composite samples representing more than 80 percent of the milk
consumed in a given population center.
These samples are analyzed for iodine-131, barium-140,
cesium-137, and potassium. All 65 samples are analyzed annually in
July for strontium-89, and strontium-90. Also, for the first month of
the three quarters beginning January, April and October, 10 regional
composite samples of milk made up from the states within each of
EPA's 10 regions are analyzed for strontium-89 and strontium-90.
Iodine131, barium-140, cesium-137 and potassium are determined
by gamma spectral analysis. Strontium-89 and strontium-90 are
determined by beta counting a total strontium precipitate which has
been chemically separated by ion-exchange.
The values from the pasteurized milk samples for October -
December 1981 are shown in Tables 18 - 20. Strontium values from
regional composite samples collected October - December 1981 are
shown in Table 21.
Tritium in Milk
It was previously proposed to analyze all 65 milk samples for
tritium in the aqueous and organic phases, on an annual basis (on the
April sample). The EERF is currently evaluating alternative
analytical techniques anticipating that these analyses will begin
during the coming year.

Plutonium and Uranium in Milk
Ten milk sampling sites near plutonium handling facilities, plus
2 sites chosen for background information, are analyzed annually for
plutonium and uranium. Analytical techniques approximate those used
for air filters.
Only plutonium analyses were performed on the 1974 samples, but
due to increased emphasis on levels of natural radioactivity, uranium
analyses were included for 1975 - 1976 samples. Data for samples
collected April 1978 were reported in ERD 14.
Iodine-129 i_n Milk
These analyses were designed to assess environmental levels of
iodine-129 around nuclear fuel reprocessing facilities. Annual
samples collected from Montgomery, Alabama (background); Idaho
Falls, Idaho; Chicago, Illinois; Buffalo, New York; and
Charleston, South Carolina; are analyzed for iodine-129 and stable
iodine-127. Results for 1978 were reported in ERD 17.
Carbon-14 JLn Milk
Nine stations, chosen for wide geographical distribution,
contribute milk samples for annual analysis for carbon-14. These
samples have monitored the carbon-14 levels in the food chain
resulting from nuclear testing.
Analysis consists of combusting the samples and measuring
released carbon dioxide through liquid scintillation.
The results of carbon-14 analysis on samples collected during
May 1974 were reported in ERD Report 2, September 1975.

SECTION V. Human Bone Program
The Human Bone Program (formerly Human Bone Network) began
operation in 1961 to obtain data on the concentration of strontium90
in man by ape and geographical region. The target population for
this network was comprised of children and young adults up to 25
years of age. The bone specimens were limited to accident victims or
persons who had died of an acute disease process that was not likely
to impair bone metabolism.
The following were operational characteristics of this program:
All samples were composited according to age and geographical
locations.
Strontium-90, plutonium-238 and -239, and calcium analyses were
performed annually on the composite samples.
No additional bone samples have been procured since FY-75.
A final report has been submitted to the Health Physics Journal
for publication.

DATA - STATE AGENCIES
Radiologic Health Section
California Department of Health
California Air Sampling Program
The Radiologic Health Section of the California Department of
Health with the assistance of several cooperating agencies maintains
a statewide air sampling network. One of the objectives of this
program is to measure and evaluate the contribution of .fixed effluent
sources to particulate activity in the air. Data from air samplers
placed in proximity to nuclear facilities are compared with
information obtained from similar equipment in communities close to
the facilities and at several "background" or control stations.
Airborne particles are collected by a continuous sampling of air
filtered through a 47 millimeter.membrane filter, 0.8 micrometer pore
size, using a Cast air pump that provides an average sampling rate of
40 liters per minute. Air volumes are measured with a direct reading
gas meter. Filters are replaced when approximately 300 cubic meters
of air are collected, i.e., on a weekly or semi-weekly schedule.
Charcoal cartridges mounted behind the filters at 10 of the 18
stations are replaced weekly.
All air samples are sent to the Department's Sanitation and
Radiation Laboratory, where the filters are analyzed for gross beta
radioactivity 72 hours after collection. Alpha activity is
determined weekly on ashed filters. Gamma spectrescopy and an
analysis for strontium-89 and strontium-90 are normally performed on
quarterly composites from each location. Immediate gamma scans are
run on any samples for which abnormal gross activity values are
observed. Charcoal cartridges are analyzed for radiolodines by gamma
spectrescopy as soon as received.
Data will be published as received.
46
-------
Radionuelides in California Milk
Although milk is only one of the sources of dietary intake of
environmental radioactivity, it is the food iten that is most useful
as an indicator of the general population's intake of radionuclide
contaminants resulting from environmental releases. The objective of
this milk sampling network is to obtain information on current
radionuclide concentrations and long-term trends. From this
information the need for further investigation or corrective public
health action can be determined.
The California network consists of 10 stations, six of which are
from dairies close to major nuclear facilities, and the other four
represent controls, composited from local milksheds in similar
geographic locations from the plants. Samples are obtained quarterly
and analyzed immediately upon receipt.* Results are reported as pCi/1
with an error of two standard deviations.
Data will be published as received.
*Radionuclides are determined by gamma spectroscopy, with the
exception of iodine-131, which is analyzed in accordance with
procedures specified in USNRC Regulatory Guide 4.3, and strontium-89
and strontium-90, which are determined by radiochemical technique.

Radiological Health Laboratory
Indiana State Board of Health
Indiana Milk Analysis Program
In order to evaluate the fallout on Indiana pasturelands, the
State has implenented a program whereby monthly milk samples from
five geographical areas are sent to the Radiological Health
Laboratory of the State Board of Health. The milk in these samples
is bottled on the same date in all five areas to provide uniform time
from pasture to the lab.
Once in the laboratory, the milk is first analyzed by gamma
spectroscopy for iodine-131, barium-140, cesium-137, and
potassiuro-40. A one pallon sample is analyzed on a 3" x 3" Nal(Tl)
scintillation crystal for 4800 seconds. A background sample of
48,000 seconds is also run. The data are analyzed to give pCi/1 for
each radionuclide.
A quarterly composite sample is saved and run for strontium-89
and -90 by ion exchange method.
Data for the third and fourth quarters of 1981 are shown in
Tables 22 -23.

Radiological Health Division
State HygJ^enic Lr.boratory of Iowa
Iowa Vi'ater Sampling Program
The radiological Health Division of the State Hygienic
Laboratory of Iowa with the assistance of the State Department of
Environmental Quality (DEQ) maintains a state-wide water sampling
program of community drinking waters, surface waters and
precipitation. All analyses with the exception of the sequential
Ra-226, -228 analyses are performed according to "Standard Methods
for the Examination of Water and Wastewater", 14th edition. The
sequential analyses for radiums are performed according to the EPA
publication, EPA-600/4-75-008, "Interim Radiochemical Methodology for
Drinking Water."
The drinking water samples are collected by DEQ regional
personnel and sent to the State Hygienic Laboratory where they are
preserved with HC1. These waters are analyzed for gross alpha and
gross beta radioactivity as a screening process. Subsequent analyses
for Ra-226, Ra-223 , Sr-90 are performed if screening levels are
exceeded. Radium levels are of primary concern in Iowa drinking
waters as those levels are elevated in deep geologic aquifers within
the state.
Surface waters are collected at eleven sites throughout the
state with site selection being determined by proximity upstream and
downstream to nuclear power plants in Iowa or those plants
discharging into rivers which are natural borders with adjoining
states. Gross alpha, gross beta, and tritium are the routine
radionucllde analyses for these samples. Strontium is of interest
when gross beta screening levels are exceeded or if nuclear weapons
testing necessitates monitoring to determine its impact on the
environment.
Background Radiation Levels, Tritium, for the first quarter,
1981, are shown in Table 24.
Gross Radiation in Precipitation for the first quarter, 1981, is
shown in Table 25.
Gross Activity in Surface Water reported as pCi/1 for the first
quarter, 1981, is shown in Table 26.
Gross Beta Activity in Air for the first quarter, 1981 is shown
in Table 27.
SDWA (Safe Drinking Hater Act) analyses for January, February
and March, 1981, are shown in Tables 28, 29, and 30 respectively.
SD'.JA Radiological analyses, quarterly recheck samples, for 1980
are shown in Table 31.
SDWA Radiological analyses for March, 1981, are shown in Table
32.
DEQ Mineral Samples for January, February, and March 1981, are
shown in Tables 33, 34, and 35 respectively.
The concentrations of Sr-90 in Iowa Milk Samples are shown in
Table 36.
