LLNL NESHAPs project 1997 annual report

NESHAP`s limits the emission of radionuclides to the ambient air from DOE facilities to levels resulting in an annual effective dose equivalent (EDE) of 10 mrem (100 ({mu}Sv) to any member of the public The EDEs for the Lawrence Livermore National Laboratory (LLNL) site- wide maximally exposed members of the public from 1997 operations were Livermore site. 0 097 mrem (0 97 {mu}Sv) (80% from point-source emissions), 20% from diffuse-source emissions), Site 300 0 014 mrem (O 14 {mu}Sv) (38% from point-source emissions, 62% from diffuse-source emissions) The EDEs were generally calculated using the EPA-approved CAP88-PC air- dispersion/dose-assessment model Site-specific meteorological data, stack flow data, and emissions estimates based on radionuclide inventory data or continuous-monitoring systems data were the specific input to CAP88-PC for each modeled source
