Record of Technical Change No.1 for Corrective Action Investigation Plan for CAU 486: Double Tracks RADSAFE Area, Nellis Air Force Range, Nevada

[摘要] Health Physics recommends that daily field screening levels be determined for gross gamma monitoring at the Double Tracks RADSAFE Area. This recommendation is predicated on the fact that there is significant daily variation in gross gamma detector response, even in the absence of a radiation source. Calculating daily field screening levels will help ensure the detection of radiation contamination in soil. The following sections of this memorandum discuss the radiation survey instruments that will be used during the characterization of the Double Tracks site, the anticipated radionuclides in the radiological source term, the survey instrument response to these radionuclides, the definition of the field screening levels, and recommendations on how to select the daily gross gamma field screening level.
