ABSTRACT: This study investigates the radiation shielding properties of newly synthesized Eu2O3-doped silicate glasses, specifically formulated as 40Li2O-05BaO-05Gd2O3-(50-x) with doping concentrations of x = 0.0, 0.1, 0.5, 1.0, 1.5, and 2.0 mol%. Utilizing the WinXcom program, we theoretically computed key parameters including mass attenuation coefficients (μm), effective atomic numbers (Zeff), effective electron densities (Ne), mean free path (MFP), and half-value layers (HVL) across various photon energy levels. The results reveal that the radiation attenuation properties are significantly influenced by both photon energy and the chemical composition of the glass. Notably, as the gamma photon energy increases, the attenuation parameters consistently decrease, while an increase in the doping concentration of Eu2O3 is associated with enhanced radiation shielding capabilities. The Eu2O3-doped glass not only avoids the hazardous effects of lead but also exhibits improved transparency and mechanical stability, making it a promising candidate for gamma radiation shielding applications. This research underscores the potential for developing effective, environmentally friendly materials for radiation protection, paving the way for further experimental validation and practical applications in safety-sensitive areas.
