Investigation of gamma-ray shielding parameters of bismuth phospho-tellurite glasses doped with varying SmO.

The gamma ray shielding parameters such as mass attenuation coefficient, effective atomic number, equivalent atomic number, exposure buildup factor, and energy absorption buildup factor were determined for the 47.5PO+45ZnO+(5-x) BiO+2.5TeO +xSmO glass system using Phy-X/PSD software in the energy range from 0.
