Environmental Radiation Data (ERD) contains data from the RadNet monitoring system
(formerly ERAMS), which is operated by the Office of Radiation and Indoor Air's National
Analytical Radiation Environmental Laboratory (NAREL) in Montgomery, Alabama. ERD is
published in both hard-copy and electronic formats. Electronic reports are available online at
http://www.epa.gov/radnet/radnet-data/erd.html and online in a searchable database at:

                          http://www.epa.gov/enviro/facts/radnet

The United States Environmental Protection Agency established RadNet in 1973 with an
emphasis on identifying trends in the accumulation of long-lived radionuclides in the environ-
ment. RadNet is comprised of a nationwide network of sampling stations that provide air
particulate, precipitation, drinking water, and milk samples.

Sampling locations are selected to provide population and geographic coverage for the United
States. The radiation analyses performed on RadNet samples may include gross alpha and gross
beta analysis, gamma analyses, and radionuclide-specific analyses for isotopes of uranium,
plutonium, strontium, iodine, radium, and tritium. This monitoring  effort also provides informa-
tion on natural background levels and possible accidental releases into the environment.

All sampling for the RadNet monitoring system (formerly ERAMS) is performed by volunteer
collectors who are frequently members of health departments or related environmental agencies
of their respective states. The National Analytical Radiation Environmental Laboratory
(NAREL), on behalf of the U.S. Environmental Protection Agency, would like to acknowledge
the time and effort of these volunteer collectors, who are so essential to the successful operation
of RadNet. The efforts of the sample collectors are especially appreciated during times of
emergency operation when sampling frequencies are increased and schedules are  sometimes
demanding.

                          Data Reporting Conventions
Every laboratory measurement involves uncertainty. When there is little or no radioactivity in a
sample, one consequence of measurement uncertainty is the possibility of obtaining a measured
value that is less than zero. Such a negative result occurs when random effects in the measure-
ment process cause the measured value for the sample to be less than that of the blank or back-
ground, which is subtracted from it. From April  1991 to December 1995, negative results were
reported as "not detected" or "ND," and gamma analysis results that were less than their
estimated measurement uncertainties were also reported as "ND." In January 1996, both of these
practices were discontinued. Although negative activities are physically impossible, the inclusion
of negative results in the report allows better statistical analysis of the data.
Results of gamma analyses are still reported as "ND" when gamma-emitting radionuclides
not detected.
are
                               Measurement Uncertainty

Each measured valuey is reported with an expanded uncertainty U=k uc(y\ which is determined
from the combined standard uncertainty uc(y) and the coverage factor k=1. The interval from
y— Uioy + C/is estimated to have a level of confidence of approximately 95 %.
                                   Significant Figures

Expanded uncertainties are reported to two significant figures. Measurement results are rounded
to the corresponding number of decimal places.
                                  Detection Capability

The minimum detectable concentrations (MDCs) for each radionuclide are shown in Table 1.
The MDC is defined as the minimum concentration that gives a 95 % probability of detection
when the detection criteria are chosen to give only a 5 % probability of false detection in a
sample that is analyte-free.

                      Airborne Particulates and Precipitation

Gross beta radioactivity measurements and certain specific analyses are performed on air partic-
ulates and precipitation samples as indicator measurements in assessing the general (national)
impact of all contributing sources on environmental levels of radiation. Continuous air samplers
collect airborne particulates at field stations representing wide geographic coverage throughout
the United States.

Filters (10 cm diameter synthetic fiber) from air samplers are changed routinely, and generally
field measurements are made with a dual-phosphor scintillation counter at least 5 hours after
collection to allow 222Rn progeny to decay. Field estimates are reported to appropriate EPA
officials by telephone or mail depending on the activity levels found; however, as of the first
quarter of 2012, NAREL no longer reports field estimates in Environmental Radiation Data.

The filters are sent to NAREL for more sensitive analysis in a gas proportional counter. Gamma
scans are performed on all filters showing gross beta activity greater than 1 pCi/m3.

All stations routinely submit precipitation samples as rainfall, snow, or sleet occurs. The precip-
itation samples are composited at NAREL into single monthly samples for each station. Each
month that precipitation occurs, an aliquant of the composited sample is  analyzed for gamma-
emitting radionuclides. NAREL discontinued gross beta analysis of precipitation in January 2010
and discontinued tritium analysis of precipitation in January 2012.

                Plutonium and Uranium in Airborne Particulates

Environmental radiation levels of plutonium and uranium are determined by the analysis of
annually composited samples (air filters) collected from the airborne particulate samplers.
Plutonium and uranium results are published in the ERD for the third quarter of the following year.

Concentrations of plutonium-238, combined plutonium-239 and 240, and uranium-234, 235, and
238 are determined by alpha-particle spectrometry following chemical separation. The volume of
air represented by the annual composite typically ranges from 120,000 to 500,000 cubic meters.

                         2.  Drinking Water Program
The RadNet drinking water program provides data on radionuclide concentrations in the nation's
drinking water supplies. Sampling sites are either major population centers or selected nuclear
facility environs.

Drinking water data are used to assess trends and anomalies in concentrations. The analysis
scheme for RadNet samples is similar to that of EPA's "National Interim Primary Drinking
Water Regulations." The analyses include (a) tritium on a quarterly basis; (b) gross alpha, gross
beta, 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 on annual composites; (d) iodine-131
on one quarterly sample per year for each station; (e) plutonium-238, combined plutonium-239
and 240, and uranium-234, 235, and 238 for stations that demonstrate gross alpha levels greater
than 2 pCi/L on annual composites; and (f) strontium-90 on one-fourth of the annual composites
on a four year rotating schedule. Composite results are published in the ERD for the third quarter of
the following year.

RadNet drinking water data should not be used to monitor compliance with drinking water regu-
lations or for comparisons to those data since different procedures for collection and analysis
may be used.

                                   Pasteurized Milk

Milk is a reliable indicator of the general population's intake of certain 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 radio-
nuclide concentrations and determine any long-term trends.

Milk samples are collected quarterly at each of the sampling sites. The samples are analyzed for
gamma-emitting nuclides, including iodine-131, barium-140, cesium-137, and potassium-40.
Total potassium concentrations in g/L are determined from potassium-40 activities assuming
natural isotopic abundances. During the third quarter collection, one-fourth of the samples are
also analyzed for strontium-90 on a four year rotating schedule.
