Atomics International environmental monitoring and facility effluent annual report 1975

Environmental and facility effluents radioactivity monitoring at Atomics International is performed by the Radiation and Nuclear Safety Unit of the Health, Safety, and Radiation Services Department. Soil, vegetation, and surface water are routinely sampled to a distance of 10 miles from Atomics International sites. Continuous ambient air sampling and thermoluminescent dosimetry is performed on site for monitoring airborne radioactivity and site ambient radiation levels. Radioactivity in effluents discharged to the atmosphere from Atomics International facilities is continuously sampled and monitored, to ensure that levels released to unrestricted areas are within appropriate limits, and to identify processes which may require additional engineering safeguards to minimize radioactivity levels in such effluents. In addition, selected nonradioactive constituents in surface water discharged to unrestricted areas are determined. This report summarizes and discusses monitoring results for 1975
