Abstract

The study of lead-free glasses for radiation shielding applications has drawn global attention. This work aimed to theoretically investigate the impact of Bi2O3 on X-ray shielding characteristics of telluro-borate-bismuth glass samples, in the 15 - 300 keV energy region. Sample S5 (55B2O3 - 5TeO2 - 20SrO - 5ZnO â 15Bi2O3) yielded highest LAC, MAC, and Zeff (1.066-252.061 cm-1, 0.249-58.893 cm2/g, and 67.81-30.16), alongside the lowest HVL, TVL, and MFP (0.003-0.650 cm, 0.009-2.160 cm, and 0.004-0.938 cm). Hence, S5 emerged as the most effective X-ray shielding glass among the samples studied.
