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 (55Bi₂O₃- 5TeO₂-20SrO-5ZnO - 15Bi₂O₃) yielded highest LAC, MAC, and Z_{e f f} (1.066 − 252.061 cm⁻¹, 0.249 − 58.893 cm² /g, and 67.81 − 30.16), alongside the lowest HV L, TV L, 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.
