Effect of Heat Treatment on Radiation Shielding Properties of Concretes

Abstract

Background: Heat energy produced in nuclear reactors and nuclear fuel cycle facilities interactions modifies the physical properties of the shielding materials containing water content. Therefore, in the present paper, effect of the heat on shielding effectiveness of the concretes is investigated for gamma and neutron. The mass attenuation coefficients, effective atomic numbers , fast neutron removal cross-section and exposure buildup factors.
