摘要

The present study investigates the influence of incorporating B2O3 with MgO on the structural and gamma radiation-shielding features of borate-tellurite-germanate glasses. The density of the studied glasses increases systematically from 3.505 to 3.673 g/cm3 with an increase in MgO content from 5 to 15 mol.%, attributed to improved compactness of the borate network and its structural disordering. The radiation-shielding performance of the prepared glasses was investigated experimentally using the NaI (Tl) scintillation detector. Significant improvements in shielding parameters like the linear attenuation coefficient (LAC), half-value layer (HVL), tenth value layer (TVL), and effective atomic number (Zeff) were observed. The LAC values increased from 0.263 to 0.277 cm−1 for S1 and S4, respectively, with an increase in MgO content at 0.662 MeV, while HVL and TVL reduced inversely, suggesting superior gamma attenuation. The findings reflect the efficacy of prepared glasses enriched with MgO content in enhancing radiation-shielding materials.
