Surplus Facilities Management Program. Post-remedial-action survey report for SNAP-8 Experimental Reactor Facility, building 010 site, Santa Susana Field Laboratories, Rockwell International, Ventura County, California
Abstract
Based on the results of the radiological assessment the following conclusions were reached: (1) soil contaminated with the radionuclides Co(60) and Er(152)Eu of undetermined origin was detected in the southwest quadrant of the Building 010 site. Co(60) was also detected in a borehole sample taken from the area that previously held the radioactive gas hold up tanks. Uranium was detected in soil from a hole in the center of the building site and in a second hole southwest of the building site. In all cases, the radionuclide levels encountered in the soil were well below the criteria set by DOE for this site; and (2) the direct instrument readings at the surface of the site were probably the result of natural radiation (terrestrial and celestial), as well as shine from the material being stored at the nearby RMDF facility. There was no evidence that the contaminated soil under the asphalt pad contributed detectable levels to the total background readings.
