THE EFFECT OF LIMITED STRIPS OF CONTAMINATION ON THE DOSE RATE IN A MULTISTORY WINDOWLESS BUILDING
Abstract
This final report of a series of five evaluates the effects of limited fields of contamination on the dose rate within multistory structures. Comparisons are made between experimentally determined results and those obtained through use of the OCD Guide for Architects and Engineers, the National Shelter Survey Computer Program, and the OCD Manual entitled The Design and Review of Structures for Protection from Fallout Gamma Radiation. The National Shelter Survey Computer Program method for correction to account for near-field limited strips of contamination contains appreciable error, because it does not differentiate between thin- and thick-floor correction factors. Recommended experimentally obtained multiplicative correction factors for both thin and thick floors are presented. Further investigation of the effects of floor thickness and floor-edge scattering is recommended. An improved computation procedure for determining the fractton of infinite-field dose rate obtained from far-field limited strips of contamination is described. Agreement is excellent between experimentally measured and computed infinite-field dose rates. The measured dose rates in the basement are higher than prodicted by computational procedures. Further below ground level investigation is recommended on a full-scale basement. Excellent agreement is shown between results obtained from the modeling technique on a phantom structure and previous full-scale results.
