Preface
Environmental Radiation Data (ERD) is compiled and distributed
quarterly by the Office of Radiation Programs' Eastern Environmental
Radiation Facility (EERF), Montgomery, Alabama, and contains data
from the Environmental Radiation Ambient Monitoring System (ERAMS).
Data frcrn similar networks operated by contributing States, Canada,
Mexico, and the Pan American Health Organization are reported in the
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
the environment.
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. 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 provides ancillary
information on natural background levels and on releases into the
environment from stationary sources such as nuclear power reactors,
fuel fabrication facilities, and reprocessing plants.
The radiocheraical procedures used by the EERF in processing the
ERAMS samples are contained in Eastern Environmental Radiation
Facility Radiochemistry Procedures Manual.

DATA - Reporting Rationale and Procedures
In 1973, the U.S. Environmental Protection Agency's Office of
Radiation Programs, established the Environmental Radiation
Monitoring System(ERAMS) to provide continuous, accurate, and usable
environmental radiation data to the public. For completeness, ERAMS
data for all specific radionuclide analyses are reported as the
counting results indicate, whether the numbers are 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 has no 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. When an average of many 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 number
is negative, zero, or positive. All reported values are
corrected for decay to the collection date.
Potassium concentrations are determined by specific
activity analyses.
Gross Analyses - The actual value of gross radioactivity
measurements will be reported, unless the value is below the
VI1
-------
minimum detectable level (MDL) at the 2 sigma confidence level,
then < minimum detectable level will be reported.
MDL is defined as the 3 sigma error of the background. A
tabulation of MDL's is given in the following table.
(2) Reported Error Terms
Each reported value for specific analyses will be
accompanied by a counting error term at the 2 sigma (95%)
confidence interval. 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.
(4) 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 measurements and certain specific
analyses are performed on air particulates 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.
Filters ( 10-cm diameter synthetic fiber ) from air samplers are
changed twice weekly and field measurements are made with a G-M
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. Gamma scans are performed on all
filters showing gross beta counts greater than 1 pCi/m3. The
laboratory obtained values are usually lower than the field estimates
due to the decay of naturally occuring radionuclides between the
times of the two measurements.
Precipitation samples are collected at these field stations
collecting air filters. These samples are also sent to EERF where
they are composited monthly for gamma scans, tritium, and gross beta
activity measurements. Plutonium-238, -239, and uranium-234, -235,
and -238 analyses are performed on samples which exceed 2 pCi/liter
gross alpha.
-------
Tables 2-4 present the monthly average gross beta
concentrations in airborne particulates for July - September 1985.
Tables 5-7 present the monthly average gross beta
concentration in precipitation July - September 1985.
The tritium in precipitation samples for July - September 1985
at the selected stations are shown in Table 8.
A compilation of individual measurements is available from the
EPA, EERF, Montgomery, AL 36109.

Plutonium and Uranium in Airborne Particulates and Precipitation
Environmental radiation levels of plutonium and uranium are
determined by the analyses of quarterly composited samples (air
filters) collected from the continuously operating airborne
particulate samplers.
Concentration of the specific isotopes of plutonium-238, -239,
and uranium-234, -235, and -238 are determined by alpha spectroscopy
following chemical separation. The volume of air represented by the
quarterly composite ranges from 25,000 to 40,000 m5 for each
quarterly composite.
Plutonium and uranium in airborne particulates data for October
- December 1984 are shown in Table 9.
Table 9.1 contains the results of plutonium and uranium analyses
on selected precipitation composite samples for 1985. The composite
samples are those ERAMS stations that have the longest history of
continuous collection.

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 reprocessing, weapons tests, and research and
defense related activities. 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 annually and shipped to the
EERF where the krypton-85 is cryogenically separated and counted in a
liquid scintillation system.
The Kr-85 results will be published when they are available.

DATA - EPA
ERAMS
SECTION II. Water Program
The ERAMS water program provides data on ambient radiation
levels in the nation's rivers, streams and drinking water supplies.
Surface Water
Quarterly grab samples are taken downstream from operating or
future nuclear facilities at 58 stations.
Surface water samples are analyzed for tritium quarterly and
specific gartma activity annually. Tritium is a primary radioactive
pollutant from nuclear power plants and weapons production
activities.
Tritium concentrations are determined by liquid scintillation
counting of distilled samples. Gamma scans are performed annually to
determine levels of gamma emitting radionuclides.
Tritium concentrations for surface water samples for July -
September 1985 are given in Table 10.
Results from the 1985 annual gamma analyses of surface water are
shown in Table 11.

Drinking Water
This program monitors ambient radiation levels in drinking water
at 78 sites. These data serve to assess trends and anomalies in
concentrations, and to compare with standards set forth in the EPA
"National Interim Prinnary 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 the 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, strontium-90, and gamma on annual composites; (c)
radium-226 if the gross alpha exceeds 2 pCi/1 and radium-228 if the
radium-226 falls between 3 and 5 pCi/1; (d) specific iodine-131 on
one quarterly sample per year for each station; and (e) an annual
composite for plutonium-238 and -239 and uranium-234, -235, and -238
for stations that demonstrate gross alpha levels greater than 2
pCi/1.
Tritium analyses are performed by scintillation counting of the
distilled samples. Gross beta and alpha are determined by
evaporating an aliquot on a stainless steel planchet for counting.
Radium-226 is determined 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 July -
September 1985 are shown in Table 12.
Plutonium and uranium analyses are similar to procedures given
for air particulate samples. Analyses were altered to coincide with
revised EPA standards. The results of 1984 composite samples are
shown in Table 13.

SECTION III. External Gamma Ambient Monitoring Program
The external gamma monitoring program, which began in October
1978r provides a continuous measurement of ambient gamma exposure
rates, including cosmic, at selected sites throughout the continental
United States. Data from this program are 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. The program consists of
approximately 22 sites representing a wide geographic coverage
throughout the country.* 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 CaF2:Mn thermoluminescent
dosiraeters(TLD's). These dosimeters are commercially available
glass-bulb type dosimeters with energy compensating shields. A group
of three 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 approximately every
three months. 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 July - September 1985 are shown in Table
17.
* Some of these sites may not return dosimeters each period and
consequently the number of sites listed may vary slightly.

SECTION IV. Milk Program
Pasteurized Milk
This is a cooperative program with the Dairy and Lipid Products
Branch, Milk Sanitation Section, Food and Drug Administration. Milk
is a reliable indicator of the general population's intake of
radionuclides since it is consumed fresh 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 and Puerto Rico. The samples are
composited, according to production, from the major milk suppliers
representing more than 80 percent of the milk consumed in a given
population center.
The 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.
Iodine-131, 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 July -
September 1985 are shown in Tables 18 - 20.
Strontium values from regional composite samples collected July
- September are shown in Table 21.

Carbon-14 jjn 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.
Data will be published as it becomes available.
