Radiological Recovery Requirements, Structures and Operations Research. Volume I: Calculational Technique for Determining Importance of Limited Strip Decontamination Procedures

摘要

The document contains a description of the CONSTRIP III computer program. The program calculates the penetration of radiation from a uniformly contaminated horizontal rectangular source area through a shielding wall to a point detector. CONSTRIP III differs from its predecessor, CONSTRIP II, developed by the National Bureau of Standards, in three major respects: the detector may be located at the rear surface of the wall as viewed from the source, calculations may be performed for a zero wall thickness (no wall present), and an option to incorporate the build-up-air-attenuation factor for cobalt-60 on a concrete slab has been included. The method of summing contributions from source-patch--wall-slab combinations is the same in both programs. The program has been completely checked against hand calculations and the output has been compared with published experimental and theoretical results for several representative problems. The program is shown to be in good agreement with these other data and is believed to be an improvement over previous techniques for solution of the barrier shield problem. (Author)
