RADIATION STREAMING IN DUCTS AND SHELTER ENTRANCEWAYS.

Abstract

This program is an analytical and experimental investigation of the streaming of gamma and neutorns through ducts and personnel shelter entranceways. The attenuation of gamma rays in concrete walled ducts having two right angle bends was measured. Both Z and U shapes were studied experimentally. The addition of a second right angle bend results in a large increase in the attenuation for gamma rays and the energy dependence of the attenuation is considerably reduced. For smaller ducts of cross section 1 by 1 foot, the attenuation of the second bend is far greater than for the larger cross section entranceway. (Author)
