Description of Source:
The U.S. Department of Energy (DOE) manages a number of facilities across the country which handle radioactive materials. These facilities may be large sites covering hundreds of square miles in remote locations or smaller sites resembling typical industrial facilities in suburban areas. In total, DOE has approximately 30 major sites that emit radiation to the air.

The Standard: 
Emissions of radionuclides, other than Radon-222 and Radon-220, shall not exceed those amounts that would cause any member of the public to receive an annual effective dose equivalent of 10 mrem/yr.

Reporting Requirements: 
Facility owners and operators must monitor and track emissions, calculate the highest effective dose equivalent to any member of the public at any offsite point where there is a residence, school, business, or office, and report this information to EPA annually. Annual reports should include a list of the radioactive materials used at the facility; a description of the handling and processing that radioactive materials undergo at the facility; a list of emission points and their distances to the nearest residence, school, business/office, and producing farm; and a description of emission controls.
