This study investigates the radiation shielding potentiality of [(78-x) TeO2-22WO3-xBi2O3;
where x=2, 5, 8] glasses within the 0.284 MeV to 1.333 MeV energy range utilizing a novel
computer program, Phy-X. The linear attenuation coefficient (LAC), half value layer (HVL),
tenth value layer (TVL), mean free path (MFP), and effective atomic number (Zeff) were
assessed to gauge the efficacy of these glasses as radiation shields. The variations in these
parameters were analyzed for different compositions of Bi2O3 (x = 2, 5, 8) within the glass
matrix. The utilization of the Phy-X software enabled a comprehensive evaluation, offering
insights into the shielding capabilities of the glasses across a broad energy spectrum. This study
contributes to advancing the understanding of material properties relevant to radiation shielding
applications, facilitating informed decisions in the design and selection of suitable shielding
materials for diverse radiation environments. After conducting this study, it was found that with
the enhancement of the ratio of Bi2O in the composition of TeO2-WO3-Bi2O3 glasses, the density,
LAC, and Zeff values were higher, while the HVL, TVL, and MFP values were lower. Considering
the HVL of the studied glasses, the following declining trend was found: TWB-2>TWB-5>TWB
8. Through analyzing the composition of these glasses, it was found that the addition of increasing
amounts of Bi2O3 instead of TeO2 decreased the HVL. Therefore, it can be concluded that Bi2O3
is a more suitable additive than TeO2.
