Radiation Protection Properties of Binary and Tertiary Tellurite Glasses: Comparative Study

The theoretical estimation of the radiation shielding property was done for a series of binary and ternary tellurite glasses. TeO2-based glasses were modified with some binary chemicals like Bi2O3, WO3, ZnO, and PbO, along with their ternary combinations including Ta2O5. Their mass attenuation coefficient, effective atomic number, and electron density have been computed to study the efficiency of such glasses in gamma-ray shielding. It has been found that the binary composition of TeO₂ + Bi₂O₃ has greater shielding efficiency than other binary glasses. Among the ternary combinations, the TeO₂ + Bi₂O₃ + PbO glass was confirmed as the most efficient material. This work testifies to the efficiency of the tellurite glasses for their use as promising materials in radiation shielding applications due to the improved performance with the addition of Bi₂O₃ and PbO. A comparative analysis is performed to determine which glass compositions offer the most efficient radiation attenuation. The results aim to guide the design of advanced radiation shielding materials for medical, nuclear, and industrial applications.
