    Environmental Radiation Data (ERD) is compiled and distributed quarterly by the Of-
fice of Radiation and Indoor Air's National Air and  Radiation Environmental Laboratory
(NAREL) in Montgomery, Alabama, and contains data from the Environmental Radiation
Ambient Monitoring System (ERAMS). Data from similar networks operated by contribut-
ing States, Canada, Mexico, and the Pan American Health Organization are reported in the
ERD  when available.
    ERAMS was established in 1973 by the United States Environmental Protection Agency
with an emphasis on identifying trends in the accumulation of long-lived radionuclides in the
environment. It is comprised of a nationwide network of sampling stations that provide air,
precipitation, surface water, drinking water, and milk samples.
    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, and radionuclide-specific analyses for  uranium, pluto-
nium, strontium,  iodine, radium, 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 NAREL to analyze the ERAMS samples are con-
tained in the Eastern Environmental Radiation Facility Radiochemistry Procedures Manual
(EPA 520/5-84-006).  Station operation and sample collection are in accordance with pro-
cedures contained in the ERAMS Manual (EPA 520/5-84-007, 008, 009).

                          Data  Reporting Rationale
    Frequently, there is little or no radioactivity in environmental media. Thus, the results
of laboratory analyses should 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.  From July 1975 to March
1991, ERAMS data were reported as calculated, whether the  results were negative, zero, or
positive. Since April 1991, negative results have been denoted as  "not detectable,"  or "ND."
For gamma analyses only, results less than the 2

                      Airborne Participates and Precipitation

    Gross 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 contributing sources on environmental levels of radiation.
    Airborne particulates are collected continuously at field stations representing wide ge-
ographic 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 after collection to allow
for the decay of natural radon isotopes and their progeny.  Field estimates are reported to
appropriate EPA officials by telephone or mail depending on the activity levels found.
    The  filters  are  sent to NAREL  for more  sensitive analyses in a low background beta
counter.  Gamma scans are  performed on all filters showing gross beta counts  greater than
IpCi/m3. 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 many field stations collecting air filters.  These
samples  are also sent to NAREL where they are composited monthly for gamma scans,
tritium, and gross beta activity measurements. A composite of the March, April, and May
precipitation samples  is analyzed for  plutonium-238  and -239/240,  and for uranium-234,
-235, and -238.
    A compilation of individual measurements is  available from the National Air and Radi-
ation Environmental Laboratory, 540 South Morris Avenue, Montgomery, AL  36115-2601.

    Tables 2-4 contain the  data from airborne particulate  samples for October-December
1995. Tables 5-7 contain the data from precipitation  samples for  October-December 1995.
Table 8 contains the data from tritium in precipitation samples for  October-December 1995
at the selected sites.

      Plutonium and Uranium in Airborne Particulates and Precipitation

    Environmental radiation levels of plutonium and uranium are determined by the analysis
of semiannually composited samples (air filters) collected from the continuously operating
airborne particulate samplers.

    Concentrations of the specific isotopes of plutonium-238 and -239/240 and uranium-234,
-235, and -238 are determined by alpha spectroscopy following chemical separation.  The
volume of air represented by the semiannual composite ranges from 60,000 to  250,000 cubic
meters.

    Plutonium and uranium results are published when they become available.

    Table 9 contains the plutonium and uranium results for the period July-December 1995.

                               2.  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  potential 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 10 contains the tritium concentration data for October-December 1995.  Table 11
contains the surface water annual gamma results for January-December 1995.
                                          15

                                  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/L, when the gross alpha (excluding radon and uranium) levels do not exceed
15 pCi/L, when tritium levels do not exceed 20,000 pCi/L, when the strontium-90 levels do
not exceed 8 pCi/L, and when the gross beta levels do not exceed 50 pCi/L.

    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/L and radium-228 if the radium-226 falls between 3 and 5 pCi/L; (d) specific iodine-
131 on one quarterly sample per year  for each station;  and (e) an annual composite for
plutonium-238 and -239/240  and uranium-234, -235, and -238 for stations that demonstrate
gross alpha levels greater than 2 pCi/L.

    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.

    Table 12 contains the data from  drinking water samples  for October-December 1995.
Table 13 contains the data on gross alpha,  gross beta,  strontium-90, and radium-226 in
drinking water for January-December 1995. Table 14 contains the plutonium and uranium
in drinking water data for January-December 1995. Table 15 contains the 1-131  in drinking
water results for January-December 1995.

                                3.  Milk Program
                                  Pasteurized Milk

    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 can  contain  several of the
biologically significant 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 approximately 55 sampling sites with at least one lo-
cated in most states,  Puerto Rico, and the Panama Canal Zone. 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 gamma emitting nuclides,  including iodine-131, barium-
140, cesium-137, and potassium. All samples collected in July are analyzed for strontium-90.
    Note:  As of the first quarter of 1995, NAREL has discontinued regional
    compositing  of milk samples for strontium-90 analysis.

    Iodine-131, barium-140, cesium-137,  and potassium are determined by gamma spectral
analysis. Strontium-90 is determined by beta counting a total strontium precipitate that has
been chemically separated by ion exchange.

    Tables 16-18 contain the concentrations of radionuclides in pasteurized milk for October-
December 1995.
