Summary
The 1983 annual average airborne gross beta activity in Livermore Valley air samples, 1.4 x 10/sup -14/ ..mu..Ci/ml, was less than 1982. Airborne /sup 238/U concentrations at Site 300 were higher than those at Livermore because of the depleted uranium (a byproduct of /sup 235/U enrichment) used in high-explosive tests at the Site. However, these concentrations were well below the standards set by DOE. The average gross alpha activity shows no significant change from 1982. The annual average beryllium concentrations were less than 1% of the local air pollution standard at both sites and can be accounted for by the natural concentrations in airborne dust. The total tritium released to the atmosphere in 1983 was 3245 Ci. Water samples exhibited gross beta and tritium activities within the ranges previously observed in these areas. Two water samples from Site 300 showed an above-average level of gross alpha activity. This activity is due to naturally occurring uranium. The discharge of tritiated water (HTO) into the sanitary sewer system in 1982 was 1.7 Ci, unchanged from the previous year. Tritium concentrations observed in local wells in 1983 were generally the same as previous years measurements. Tritium levels found in the Livermore Valley and Site 300 vegetation were comparable to 1982. The 1983 average annual gamma-radiation doses at the Laboratory perimeter and off-site locations were 51 mrem and 50 mrem, essentially unchanged from previous year. A 14-MeV neutron generator (Bldg. 212) near the south perimeter continued to be a source of elevated radiation. 19 references, 19 figures, 36 tables. (MDF)
