AN EXPERIMENTAL EVALUATION OF ROOF REDUCTION FACTORS WITHIN A MULTI-STORY STRUCTURE

Abstract

Fallout contamination deposited on the roof of a structure is, in many cases, the source of the primary radiation component of the total dose obtained at any point within the structure. Experiments were performed in which the doses from a source of radiation present on a roof were measured in many locations within a multi-story building. This report presents the results of these experiments for roof and floor mass thicknesses of 48.6 and 97.2 psf. Comparisons of the experimentally measured gamma doses with those determined theoretically have been shown throughout this report. Agreement between experiment and theory has, in general, been found to be good.
