Radiological Characterization of High Dose-Rate Contaminated Soil Boxes by ISOCS TM Gamma Spectroscopy Scope: • Tank W-1A at Oak Ridge National Laboratory (ORNL) collected wastes from three high-radiation- level analytical facilities between 1951 and 1986. A groundwater contamination plume containing Cs-137, transuranics, uranium, and other isotopes emanated from contaminated soil surrounding the tank. URSiCH2M Hill Oak Ridge (UCOR) was the DOE environmental management contractor responsible for the removal action for the tank and surrounding contaminated soils under CERCLA. • Approximately 1000 cubic yards of contaminated soils and associated wastes were placed in lead-shielded B-25 boxes for disposition as low level waste to the Nevada National Security Site
