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 from 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.

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 number 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. When 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 number
is negative, zero, or positive. All reported values are
corrected for decay to the collection date.
vn
-------
Gross Analyses * The actual value of gross radioactivity
measurements will be reported, unless the value is below the
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. 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.
(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, Virgin Islands, and the Panama
Canal.
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 laboratory gross beta counts greater than 1
pCi/rn^. 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. Plutonium-238, -239, and uraniumr234,
"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 April * June 1984.
Tables 5*7 present the monthly average gross beta
concentration in precipitation April * June 1984.
The tritium in precipitation samples for April * June 1984 at
selected stations are shown in Table 8.
A compilation of individual measurements is available from the
EERF, Montgomery, AL 36109.

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 67 continuously operating airborne
particulate samplers.
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 gassing through the filters normally ranges from
25,000 to 40,000 m3 for each quarterly composite.
Plutonium and uranium in airborne particulates data for October
A December 1983 will be published when available.

-------
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 alsa 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 ambient radiation data to
assess the effects of nuclear fallout, 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 April
June 1984 are given in Table 9.

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,- strontium-90 and gamma on annual composites.
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, for
stations which demonstrate gross alpha levels greater than 2 pCi/1.
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 April
June 1984 are shown in Table 10.
All samples were taken as either a single grab sample or
composite samples taken over 12 to 14 days.

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 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 due to weapons fallout, reactor
operations, etc. 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
dosimeters(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 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 April - June 1984 are shown in Table 11.
* Some of these sites may not return dosimeters each period and
consequently the number of sites listed may vary slightly.
** Starting October, 1984, this program will change to a
quarterly cycle.

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*l40,
cesiunr"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 regio.ns are analyzed for strontium*-89 and
strontiunr*90.
Iodine^-131, barium^l40, cesiunr-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 April * June
1984 are shown in Tables 12 - 14.
Strontium values from regional composite samples collected April
- June 1984 are shown in Table 15.
Carbon-14 in 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.
