Environmental Radiation Data(EKD) is compiled and published quarterly by the Office of
Radiation and Indoor Air's National Air and Radiation Environmental Laboratory (NAREL) in
Montgomery, Alabama, and contains data from the RadNet monitoring system (formerly
ERAMS). ERD is published in both hard-copy and electronic formats.  Electronic reports are
available online atwww.epa.gov/narel.

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 these samples include gross alpha and gross beta
analysis, gamma analyses, and radionuclide-specific analyses for uranium, plutonium, 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 RadNet samples are contained in
the NAREL Radiochemistry Procedures Manual. Station operation and sample collection  are in
accordance with procedures contained in the ERAMSManital(EPA 520/5-84-007, 008, 009).

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 Air and 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 are
not detected.
                               Measurement Uncertainty

Each measured valuers reported with an expanded uncertainty U=k uc(y), which is determined
from the combined standard uncertainty uc(y) and the coverage factor k=2. The interval from
y - Utoy + Uis 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.

                                  1. 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
throughout the United States.

Filters (10-cm diameter synthetic fiber) from air samplers are changed twice weekly and field
measurements are made with a dual-phosphor scintillation counter 5 hours after collection to
allow natural radon isotopes and their progeny to 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 analysis in a low background proportional
counter. Gamma scans are performed on all filters showing gross beta activity greater than
1 pCi/m3. The laboratory obtained values are usually lower than the field estimates because of
the decay of naturally occurring radionuclides during the time between the two measurements.

All stations routinely submit precipitation samples as rainfall, snow, or sleet occurs. The
precipitation 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
tritium and gamma-emitting radionuclides. NAREL discontinued gross beta analysis of
precipitation beginning in January, 2010.

A compilation of individual measurements is available from the National Air and Radiation
Environmental Laboratory, 540 South Morris Avenue, Montgomery, AL 36115-2601.

                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 continuously operating airborne
particulate samplers.

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.

Plutonium and uranium results are published when they become available.

                         2.  Drinking Water Program
The RadNet drinking water program provides data on radionuclide concentrations in the nation's
drinking water supplies. Samples are taken at 78 sites which are either major population centers
or selected nuclear facility environs.

Drinking water data are used 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.

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; and (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.

                                  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.

Quarterly samples are collected at approximately 55 sampling sites. 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-40. Total potassium concentrations in g/L are determined from
potassium-40 activities assuming natural isotopic abundances. During the third  quarter collec-
tion, one-fourth of the samples are also analyzed for strontium-90 on  a four year rotating
schedule.
