This study investigates the gamma-ray shielding properties of Bi-Se-Ge chalcogenide glasses using advanced computational tools. The Phy-X/PSD and FLUKA programs were utilized to determine critical shielding parameters such as linear attenuation coefficient ($GLAC$), mass attenuation coefficient ($GMAC$), half-value layer ($GHVL$), mean free path ($GMFP$), and effective atomic number ($Zeff$). Our findings reveal that these glasses exhibit superior shielding capabilities compared to traditional materials. For instance, the $GMAC$ values for the glasses ranged from 101.472 cm2/g to 177.475 cm2/g at a photon energy of 0.015 MeV. Additionally, the $GHVL$ values decreased significantly with increasing Bi content, from 4.082 cm to 3.104 cm at an energy level of 15 MeV. The effective atomic number ($Zeff$) also increased from 36.12 to 53.23 with higher Bi concentrations. These insights, derived from precise computational analysis, highlight the potential of Bi-Se-Ge glasses for applications in radiation protection. The discussion also examines the impact of substituting Bi atoms with Se on the shielding capabilities of the original Bi-Se-Ge glass.

Future work will focus on experimental validation of these results to further substantiate our findings.
