Other Monitoring
RadNet is one of the main programs that monitors the radioactivity associated with air, precipitation, drinking water and milk, but there are also other state, federal and private programs that monitor environmental radiation.
DOE's Los Alamos National Laboratory, in cooperation with EPA, operates
the Neighborhood Environmental Watch
Network (NEWNET) 
.
This network measures gamma radiation
exposure rate, humidity, barometric
pressure, wind speed and wind direction utilizing real-time monitoring
devices with satellite uplink at locations in Alaska, California, Mississippi,
Nevada, New Mexico and Utah. The majority of the sampling sites are located
in Nevada in support of monitoring efforts at the Nevada Test Site and
in New Mexico in support of monitoring efforts at Los Alamos National
Laboratory.
In the United States, DOE has responsibility for research and development for monitoring and verification of the Comprehensive Test Ban Treaty (CTBT). In support of the CTBT, which was signed by President Clinton in September 1996, an International Monitoring System and National Data Center are currently being developed. The monitoring system will consist of a worldwide network of seismic, hydroacoustic, infrasonic, and radionuclide monitoring stations which will provide real-time data to the proposed National Data Center. There will be eighty radionuclide monitoring stations world wide. Eleven radionuclide monitoring stations will be located in the United States.
Some states also perform radiation monitoring. For example, the Illinois Department of Nuclear Safety operates a system composed of gamma dose rate monitoring devices and air particulate sampling at approximately 60 sites. The program, however, is basically directed at instate nuclear power plants. Similarly, other radiation monitoring systems in the country focus on facility and site monitoring and special studies monitoring. With the exception of RadNet, a comprehensive national environmental radiation monitoring which focuses on major population centers and broad geographical coverage network does not exist.
