RADIATION STREAMING IN SHELTER ENTRANCEWAYS

Abstract

The objective of this program is an analytical and experimental investigation of nuclear radiation streaming in ducts and shelter entranceways. The energy dependence of duct attenuation was extended for gamma rays. Further duct geometry dependence was also measured. Thermal neutron attenuation was determined for a non-point source and the neutron attenuation was found to be extremely small. Use of albedo theory to successfully describe the radiation streaming of gamma rays was further strengthened and a computer code was prepared to describe the streaming in a straight duct. The code will represent a tremendous labor saving device for future calculations. An analytical analysis of a straight duct, using albedo theory, is included in the appendix along with an outline of future research needs.
