Abstract
The purpose of this research was to investigate the shielding characteristics of high-amount heavy metal oxide and Eu3+-activated borate glasses based on 10La2O3–50HMO–(40–x) B2O3–xEu2O3 (x = 0, 0.5, 1, 2, and HMO = PbO, Bi2O3). Critical gamma radiation attenuation characteristics, particularly mass attenuation coefficients of investigated heavy metal oxide glass samples, were determined using Monte Carlo simulations and the Phy-x/PSD software. Following that, we looked at the half-value layer, mean free path, effective atomic number, and build-up factors across a broad energy range (0.015–15 MeV). According to the study’s results, the addition of Eu2O3 enhanced the mass attenuation coefficient and effective atomic number, while reducing the half-value layer, mean free path, and accumulation factors. In terms of gamma radiation attenuation, the LBi50BEu glass system surpassed the LPb50BEu glass system in terms of overall shielding properties against nuclear radiation. Additionally, the heavy metal oxide glass’ efficacy as a neutron shield was determined using fast neutron removal cross-sections (ΣR). LBi50BEu2 glass was shown to be more effective in preventing the penetration of charged particle radiation.
Highlights
With today’s extensive use of radiation sources and radioactive materials, it is extremely essential to use radiation sources cautiously and safely

Summary
With today’s extensive use of radiation sources and radioactive materials, it is extremely essential to use radiation sources cautiously and safely. Pb’s negative impacts on human health and the environment pose a serious concern It has some disadvantageous material properties, such as optical non-transparency, low durability, high cost, and material durability in terms of shielding applications [1]. Another material used to attenuate gamma radiation is concrete. Impurities in the form of metals were incorporated into regular glass to transform it into a radiation shield glass This doping, especially with heavy metal oxides (Ba, Bi, Pb), enhances the glass’ attenuation properties, making it ideal for shielding applications. Researchers will gain a better understanding of the utility of HMO-doped glasses as nuclear-radiation-shielding materials as a result of the findings of this study
