SLAC, a high-energy (GeV) electron accelerator facility, performs experimental and theoretical research using high-energy electron and/or positron beams that can produce secondary neutron and gamma radiation when beam losses occur. Radioactive air production (mainly 11C, 13N, 15O, 41Ar) and release is one of the environmental protection program issues. DOE Order 458.1 requires that 40 CFR 61 Subpart H's NESHAPs requirements be followed. These regulations prescribe a total dose limit of 10 mrem y-1 to the Maximally Exposed Individual (MEI) of general public, a requirement for a continuous air monitoring system if a release point within a facility can cause > 0.1 mrem y-1 to the MEI, and a requirement for periodic confirmatory measurements for minor sources which give releases that contribute Show Partial Abstract
