-------
       I he National Air and
        Radiation Environmental
        Laboratory (NAREL) is a
        comprehensive environmen-
tal filiation laboratory managed by
the U.S. Environmental Protection
Agency's Office of Radiation Pro-
grams. The NAREL is located on
Gunter Air Force Base in Montgom-
ery, Alabama, and provides services
to a wide range of clients, including
other EPA offices, Federal and State
agencies, and, in some cases, the
private sector. The NAREL facilities
incorporate state-of-the-art laboratory
technology and equipment and
include the latest health and safety
techniques, as well as strict monitor-
ing and control of laboratory emis-
sions.
    The NAREL staff is highly trained
with professional backgrounds
encompassing health physics,
radiochemistry, engineering, math-
ematics, and computer science.
Fundamental to the NAREL mission is
the commitment to developing and
applying the most advanced methods
for measuring environmental radioac-
tivity and evaluating its risk to the
public.

RADON
The NAREL provides analytical support to
surveys of radon concentrations in homes,
schools, and other public buildings across
the United States. Measurements are

NATIONAL ENVIRONMENTAL
MONITORING
The Environmental Radiation Ambient
Monitoring System (ERAMS) is a national
network of monitoring stations that
regularly collect air, water, precipitation,
      Over 6.000 ERAMS samples are received and
                       analyzed annually.
NUCLEAR EMERGENCY
RESPONSE
The NAREL emergency response team is
trained and equipped to respond to nuclear
emergencies anywhere in the world. A
mobile radioanalytical laboratory and the
    Team personnel and equipment can be deployed
      within 24 hours of a radiological emergency.
SUPERFUND AND FEDERAL
FACILITY CLEANUP
A growing concern for the country is
radioactive contamination at Superfund

leader in developing procedures for site

                                    The NAREL analyzes about 10,000 samples
                                    annually. Typical samples can include air,
                                    water, soil, vegetation, human tissue, and
                                    food and are analyzed for a number of
                                    radionuclides.  NAREL chemists are

50,000 canisters are analyzed each year.
    NAREL's radon exposure chambers
represent the most advanced technology.
Over 700 companies participating in
EPA's Radon Measurement Proficiency
Program have come to the laboratory to
demonstrate their proficiency in measur-
ing radon by exposing their measurement
devices in these chambers. Successful
companies are listed in an EPA publication
that is distributed to State health agencies
and the public.

COMPUTER DOSE MODELS
The dispersion of radioactivity into the
environment and the resulting risks to the

consequences of potential releases of
radioactivity into the air, land, or water.
INTERAGENCY PROGRAMS
The quality of NAREL staff and facilities is
well recognized by States and other
Federal agencies. The laboratory has in
the past performed surveys, at the request
of the U.S. Naval Sea Systems Command,
of harbors serving naval nuclear vessels.

The NAREL has conducted indoor radon
survey programs nationally for agencies such
as the National Park Service, the U.S.
Forestry Service, and the General Service
Administration. States rely on the NAREL for
training, instrument calibration, and radio-
chemical analysis. Cooperative effort
between EPA and other Federal and State
agencies is a hallmark of the NAREL
program.
