RADIATION STREAMING IN SHELTER ENTRANCEWAYS

Abstract

The basic objective of the work reported herein is to study, describe and measure the transport of nuclear radiation through air ducts having walls of different materials. Particular emphasis is placed on full scale concrete ducts which are intended for use as underground shelter entranceways and contain a right angle bend. It is shown that a modified albedo theory will rather accurately describe the transmission of both gammas and neutrons in lead and concrete ducts. Theory is compared with experimental measurements of gamma dose and neutron flux attenuation factors. Neutron number albedo measurements are made and reported. Work by various theorists and experimenters are included for completeness and comparison. This program rather clearly points out direction future programs should take and the areas in which major emphasis is needed.
