Radioactivity in gaseous waste discharged from the separations facilities during 1984

The radioactivity in gaseous wastes discharged by Rockwell Handford Operations (Rockwell) during CY 1984 is summarized. During CY 1984, 77 stacks discharged gases which were normally contaminated or potentially contaminated with radioactive material. No air concentrations resulting from 200 Area effluents were above or even near DOE requirements. Also, all stack emissions were below Rockwell administrative controls based on the as low as reasonably achievable philosophy. Discharge measurements showed that 100% of the total alpha activity was discharged by the following stacks: 291-A-1 (98%), 291-Z-1 (1%) and 291-T-1 (1%). Additionally, 99% of all the total particulate beta activity was discharged by 2 stacks: 291-A-1 (98%) and 291-B-1 (1%).
