1. Air Program
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 meterj at 5 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 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, -239, -240, and 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 July-September 1995.
Tables 5-7 contain the data from precipitation samples for July-September 1995. Table 8
contains the data from tritium in precipitation samples for July-September 1995 at the
selected sites.
J 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 semiannually composited samples (air filters) collected from the continuously operating
airborne particulate samplers.
Concentrations of the specific isotopes of plutonium-238, -239, and -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.
16
-------
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 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 tritium concentration data for July-September 1995.

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, -239, and -240 and uranium-234, -235, and -238 for stations that demon-
strate 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 10 contains the data from drinking water samples for July-September 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 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 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 11-13 contain the concentrations of radionuclides in pasteurized milk for July-
September 1995. Table 14 contains the concentrations of strontium-90 in pasteurized milk
for July 1995.
