In 1990, the Remote Sensing Laboratory (RSL) of EG G Energy Measurements, Inc. (EG G/EM) conducted in situ radiological surveys at the Rocky Flats Plant near Golden, Colorado. The Old Landfill Area was surveyed from October 25 through November 7, and an area east of the 903 Pad was surveyed from November 8 through December 8. As a precursor to the Old Landfill survey, an area south of the landfill along the north bank of Woman Creek was previously surveyed from August 29 through 31. The August survey employed a 20% N-type, high purity germanium (HPGe) gamma ray detector suspended one meter above ground level (AGL). The later surveys employed a similar detector, but it was suspended 7.5 meters AGL. The processed data from the Old Landfill indicated that detected radioisotopes were generally consistent with those expected from normal background emitters. However, there was clear evidence of soil disturbance, and there were areas of elevated concentrations of uranium-238 ({sup 238}U). The processed data from the area east of the 903 Pad confirmed on earlier survey which indicated the presence of americium-241({sup 241}Am) in surface soils. Both of the surveyed areas were part of ongoing, remedial investigations of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) at various Rocky Flats sites. EG G/EM is an independent contractor for the United States Department Energy (DOE) and conducts in situ and aerial radiological surveys at the DOE's request. 22 figs., 3 tabs.
