Gamma, Fast Neutron, Proton, and Alpha Shielding Properties of Borate Glasses: A Closer Look on Lead (II) Oxide and Bismuth (III) Oxide Reinforcement

The purpose of this research was to investigate the shielding characteristics of high-amount heavy metal oxide and Eu3+-activated borate glasses based on 10La(2)O(3)-50HMO-(40-x) B2O3-xEu(2)O(3) (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 (sigma(R)). LBi50BEu2 glass was shown to be more effective in preventing the penetration of charged particle radiation.

Automated summary

This research focused on studying the shielding characteristics of heavy metal oxide and Eu3+-activated borate glasses, determining important gamma radiation attenuation properties through simulations, and analyzing various parameters within a wide energy range. Results showed that the addition of Eu2O3 improved the glass' shielding performance, with LBi50BEu2 glass being more effective against charged particle radiation.
