Investigations of Building Materials as Gamma Ray Shielding Materials

Abstract

To check the feasibility of the use of some building materials such as cement, plaster of paris, lime and sand as gamma ray shielding materials, some parameters of dosimetric interest has been investigated at some incident photon energies (59.54 to 1332 keV). The photon interaction with building materials has been discussed mainly in terms of mass attenuation coefficients and exposure buildup factors. From the present investigations, it has been concluded that among the selected materials, lime acts as best gamma ray shielding material, due to its higher values for mass attenuation coefficient and least values for exposure buildup factor in the selected energy range.
