Computational Evaluation of Gamma-Ray Shielding Properties of SrO–Al₂O₃–MoO₃–B₂O₃–TeO₂ Boro-Tellurite Glasses via Phy-X/PSD

Abstract

This study investigates the gamma-ray shielding performance of SrO–Al₂O₃–MoO₃–B₂O₃–TeO₂ glass systems using the Phy-X/PSD simulation software. Conventional shielding materials such as lead and concrete are widely used but have significant limitations, including toxicity, high weight, and lack of transparency. As a result, researchers are exploring glass-based alternatives that provide safer, more versatile radiation protection. In this work, key shielding parameters, including mass attenuation coefficient, linear attenuation coefficient, half-value layer, mean free path, and radiation protection efficiency, were simulated at photon energies of 0.184, 0.280, 0.662, 0.710, and 0.810 MeV, corresponding to commonly used medical and industrial gamma sources. The influence of compositional variations, particularly between B₂O₃ and TeO₂, was also examined to understand how these oxides affect the density and photon-interaction behavior of the glasses. The results demonstrate that increasing TeO₂ content enhances shielding effectiveness across all energies. Overall, the study provides meaningful reference data and highlights the value of simulation as a cost-effective alternative for institutions with limited experimental facilities, especially in developing countries.
