In this paper, the interaction of gamma rays with some shielding materials has been studied. The total mass attenuation coefficient () for eight shielding materials has been calculated by using WinXCOM program in the energy range from 1keV to 100GeV. Also, the effective atomic number () and the effective electron density () were calculated using the values of the total mass attenuation coefficient. The dependence of these parameters on the incident photon energy and the chemical composition has been examined.
