Abstract
The γ-ray shielding parameters were evaluated using the Monte Carlo simulation for a quadrable glass system consisting of LiF-MgO-Bi2O3- SiO2 in the γ-ray energy interval extended between 0.284 MeV up to 1.332 MeV. The substitution of MgO by SrO compounds was studied in the present work where the raising SrO concentration was between 0 and 20 mol.% enhances slightly the linear attenuation coefficient of the fabricated glasses from 0.507 cm−1 to 0.514 cm−1, at a gamma ray energy of 0.662 MeV. The enhancement in the linear attenuation coefficient leads to a decrease in the half values thickness and the lead equivalent thickness for the investigated samples. The results from this work demonstrated that replacing magnesium with strontium led to improve radiation protection ability of the glasses.
