TECHNICAL BASIS DOCUMENT OF MARSSIM FIELD CALIBRATION FOR QUANTIFICATION OF CS-137 VOLUMETRICALLY CONTAMINATED SOILS IN THE BC CONTROLLED AREA USING 2 BY 2 SODIUM IODIDE DETECTORS
Description: The purpose of this paper is to provide the Technical Basis and Documentation for Field Calibrations of radiation measurement equipment for use in the MARSSIM Seeping Surveys of the BC Controlled Area (BCCA). The Be Controlled Area is bounded on tt1e north by (but does not include) the BCCribs & Trenches and is bounded on the south by Army Loop Road. Parts of the BC Controlled Area are posted as a Contamination Area and the remainder is posted as a Soil Contamination Area. The area is approximately 13 square miles and divided into three zones (Zone A , Zone B. and Zone C). A map from reference 1 which shows the 3 zones is attached. The MARSSIM Scoping Surveys are intended 10 better identify the boundaries of the three zones based on the volumetric (pCi/g) contamination levels in the soil. The MARSSIM Field Calibration. reference 2. of radiation survey instrumentation will determine the Minimum Detectable Concentration (MDC) and an algorithm for converting counts to pCi/g. The instrumentation and corresponding results are not intended for occupational radiation protection decisions or for the release of property per DOE Order 5400.5.
