STRUCTURE SHIELDING FROM SIMULATED FALLOUT GAMMA RADIATION.
Abstract
Experiments were performed to evaluate the application of the presently-used structure shielding theory to structures of simple geometry. The shape factor verification experiments yielded results which the theory predicted to within 15%. For the interior partitions experiments, the theory predicted the experimental results to within 10% in most cases and 20% in all cases. For the structures with outer-wall apertures and no interior partitions, theory and experiment agree to within 15%. Introduction of the interior partition, however, causes theoretical predictions to be up to 50% lower than experimental results at detector locations opposite the aperture, apparently caused by the failure of the theory to account for radiation scattering effects by the interior partition. The results of the basement shielding experiments showed good agreement between theory and experiment for structures with no floor. However, the theory was a factor of 3 lower than the experimental results for structures with a 1/2-in. (20 psf) steel floor, indicating the requirement for a change in the floor barrier reduction factor currently used in the theory. (Author)
