In this study, the effect of Bi2O3 incorporation on the radiation shielding performance of BaO
Fe2O3–SrO–B2O3 glass matrices (abbreviated as BBFSB) was systematically evaluated. Using the EGS4
calculation code, the shielding properties were determined and then compared with the data generated by
XCOM. An increase in glass density from 3.770 g/cm³ to 5.00 g/cm³ was observed when the Bi2O3
concentration was increased. Several key shielding parameters were determined, including the half value
layer (HVL), mean free path (MFP), radiation protection efficiency (RPE), fast neutron macroscopic
cross-section ER (cm−1) and gamma–ray kerma coefficients (K). The results indicate that increased BiO₃
concentrations significantly improve the material's radiation shielding properties, especially with regard
to photon and neutron attenuation, which strengthens the glass system's overall shielding power.
