Preface
Environmental Radiation Data (ERD) is compiled and distributed quarterly by the Office of Radiation
Programs' Eastern Environmental Radiation Facility (EERF) in 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 upon 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 Assion
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 routine and
accidental releases into the environment from stationary sources.
The radiochemical procedures used by the EERF to analyze the ERAMS samples are contained in
Eastern Environmental Radiation Facility Radiochemistry Procedures Manual (EPA 520/6-84-006). Station
operation and sample collection are in accordance with procedures contained in the ERAMS Manual (EPA
520/5-84-007, 008, 009).

DATA - Reporting Rationale and Procedures
In 1973, the U.S. Environmental Protection Agency's Office of Radiation Programs established the
Environmental Radiation Ambient 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 calculated results indicate, whether the numbers are negative, zero, or positive.
Reporting Rationale
Frequently, there is little or no radioactivity in environmental media. Thus, the results of laboratory
analyses should statistically show a distribution of negative and positive numbers about zero. A negative
value occurs when a previously determined background value is subtracted from a sample value that is
less than that of the background. 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 that indicate that the true value of a distribution
is near zero. When an average of many measurements produces a result significantly less than zero, this
indicates a bias in the measurement procedure.
(1) Reported Values
Specific Analyses. All specific radionuclide analyses will be reported as the counting results indicate,
whether the value is negative, zero, or positive. All reported values are corrected for radioactive decay
to the collection date.
Gross Analyses. The actual value of gross radioactivity measurements will be reported, unless
the value is below the minimum detectable level (MDL) at the Iff confidence level, then < minimum
detectable level will be reported.
MDL is defined as the 3

AMBIENT MONITORING SYSTEM (ERAMS)
Section I. Ait Program
Airborne Particulates and Precipitation
Gtoss beta radioactivity measurements and certain specific analyses are performed on air participates
and precipitation samples as indicator measurements in assessing the general (national) impact of all con-
tributing sources on environmental levels of radiation.
Airborne participates 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 measure-
ments are made with a G-M survey meter t 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/m8. The laboratory obtained
values are usually lower than the field estimates due to the decay of naturally occurring radionuclides between
the times of the two measurements.
Precipitation samples are collected at those 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 mea-
surements. A composite of the March, April, and May precipitation samples is analyzed for plutonium-238,
-239, -240, and uranium-234, -235, and -238.
A compilation of individual measurements is available from the Eastern Environmental Radiation Fa-
cility, 1890 Congressman W.L. Dickinson Drive, Montgomery, AL 36109.
Tables 2-4 contain the data in airborne particulate samples for July - September 1989. Tables 5-7
contain the data in precipitation sample for July - September 1989. Table 8 contains the data for tritium
in precipitation samples for July - September 1989 at the selected sites.
' The counts at five hours for the Montgomery, Alabama, station are performed on a low background beta counter.

Plutonium and Uranium in Airborne Particulates and Precipitation
Environmental radiation levels of plutonium and uranium are determined by the analysis of semi-
annually composited samples (air filters) collected from the continuously operating airborne particulate
samplers.
Concentration of the specific isotopes of plutonium-238, -239, and -240 and uranium-234, -235, and
-238 ate determined by alpha spectroscopy following chemical separation. The volume of air represented by
the semiannual composite ranges from 25,000 to 40,000 cubic meters.
Plutonium and uranium results are published when they become 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 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. Krypton-85 in the atmosphere
has been monitored 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 and
shipped to the EERF where the krypton-85 is cryogenically separated and counted in a liquid scintillation
system.
The last Kr-85 results were for 1976, 1977, and 1979. They were published in Environmental Radiation
Data: Report 30.

ENVIRONMENTAL RADIATION
AMBIENT MONITORING SYSTEM (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 gamma 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.
Table 9 contains the data for tritium concentrations for July - September 1989.

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 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 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, -239, and -240 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 al-
pha 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.
Table 10 contains the data in drinking water for July - September 1989. Table 11 contains the data
on gross alpha, gloss beta, strontium-90, and radium-226 in drinking water for January - December 1988.
Table 12 contains the plutonium and uranium in drinking water data for January - December 1988.

ENVIRONMENTAL RADIATION
AMBIENT MONITORING SYSTEM (ERAMS)
Section III. External Gamma Ambient Monitoring Program
The external gamma monitoring program, which began in October 1978, provides a continuous measure-
ment 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 wide'geographic coverage throughout the
country.' Although exposure measurements at these few sites are not totally representative of nationwide
exposures, they do indicate national trends.
The monitoring program utilizes CaF3: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 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.
Table 13 contains the data for environmental gamma ambient monitoring program July - September
1989,
Some of the»e *ites may not return dosimeter* each period fcnd consequently the number of files listed may vary (lightly.

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 fiesh by a large segment of the population and can contain several of the biologically
important radionuclides that result 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 Zone, The samples are composited, according to production, from the major milk
suppliers representing mote than 80 percent of the milk consumed in a given population center.
The samples are analyzed for gamma emitting nuclides, which include iodine-131, barium-140, cesium-
137, and potassium. All samples collected in July are analyzed 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. Stron-
tium-89 and strontium-90 are determined by beta counting a total strontium precipitate that has been
chemically separated by ion exchange.
Tables 14-16 contain the concentrations of radionuclides in pasteurized milk for July - September 1989.
Table 17 contains the concentrations of strontium-90 and strontium-89 in pasteurized milk EPA Location

Carbon-14 in Milk
Nine stations, chosen for wide geographical distribution, contribute milk samples for annual analysis
of carbon-14. These samples are monitored for carbon-14 levels in the food chain resulting from nuclear
testing. The pasteurized milk is freeze-dried and the resulting powder is pelletized for ease of combustion.
Analysis consists of combusting the samples and converting the released carbon dioxide through a series of
chemical conversions to benzene and finally measured by liquid scintillation.
The samples undergo three main steps in the chemical conversions to benzene prior to liquid scintillation
counting. They include (1) combustion of the sample to carbon dioxide, (2) conversion of the carbon dioxide
to acetylene, and (3) trimerizations of the acetlyene to benzene. Tables 18-21 contain the results of
carbon-14 analysis on samples collected during 1983, 1984, 1985, and 1986.
