This study systematically evaluated the gamma-ray shielding abilities of borosilicate glass
samples with the chemical formula 70B2O3–5SiO2–10Li2O–5Bi2O3–10ZnO–XEr2O3 and X = 0.0 (Er-0.0)
to 1.2 (Er-1.2) mol% (abbreviated as BSLBZE). Using the EGS4 calculation code, shielding properties
were determined for a total of 20 energies from 0.05 MeV to 2 MeV and then compared with data
generated by XCOM. An increase in glass density from 2.95 g/cm³ to 3.12 g/cm³ was observed when the
Er2O3 concentration was increased. A number of important radiation shielding parameters, such as
gamma-ray kerma coefficients (kγ), radiation shielding efficiency (RPE), mean free path (MFP), fast
neutron macroscopic cross section ΣR (cm−1) and half-value layer (HVL), were determined. Samples with
increased erbium doping have higher values for radiation protection efficiency (RPE), gamma-ray kerma
coefficients (ĸ), and the fast neutron macroscopic cross-section ΣR (cm⁻¹), whereas the half-value layer
(HVL) and mean free path (MFP) have lower values. The results demonstrate that increasing Er₂O₃
concentrations gradually improve the material's radiation shielding properties, with notable effectiveness
in photon and neutron attenuation. This development significantly improves the glass matrix's overall
shielding capabilities.
