and average concentrations of radioactive material discharges from the facility.
Guidance for uranium recovery monitoring programs can be found in Table 2 of Regulatory Guide 4.14. This guide recommends that licensees perform:
Requirements for conducting an effluent monitoring program at the U.S. Department of Energy-owned gaseous diffusion plants are provided in 40 CFR 61, Subpart H. This subpart requires radionuclide emission measurements to be made at all release points that have a potential to discharge radionuclides into the air in quantities that could cause an effective dose equivalent in excess of 0.1 mrem per year to any member of the public. Confirmatory measurements are required for other release points that have a potential to release radionuclides into the air. The subpart also contains specific requirements for measurement and analysis procedures using approved methods and for quality assurance.
