Özet

This study investigates the radiation shielding capabilities of glass systems made of 8B2O3-(88-x)SiO2-4Li2O-xFe2O3 (with x varying from 0 to 30 wt%) using computational programs and GATE Monte Carlo simulations. According to the results, glass compositions containing 30 wt% Fe2O3 exhibit better radiation shielding properties than other ratios. Particularly, these compositions show improved radiation attenuation with lower Energy Absorption Buildup Factor (EABF), Exposure Buildup Factor (EBF), and Half Value Layer (HVL) values. Furthermore, they show higher mass attenuation coefficient (MAC) and linear attenuation coefficient (LAC) values, suggesting increased effectiveness in absorbing radiation per unit mass or thickness. Additionally, the glass with 30 wt% Fe2O3 displays a higher effective removal cross-section value, strengthening its potential as an absorbent material for both gamma and neutron radiation shielding. These results indicate the potential use of glass systems modified with Fe2O3 in radiation shielding technology. Moreover, molecular dynamics simulations were performed to determine distinct melting onset temperatures: 665–1760 K for Fe-free and 1024–1846 K for Fe-containing materials.
