Abstract

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.

Fe2O3对B2O3-SiO2-Li2O玻璃辐射屏蔽效率的影响

本研究利用计算程序和GATE蒙特卡罗模拟研究了由8B2O3-(88-x)SiO2-4Li2O-xFe2O3 （x从0到30 wt%不等）制成的玻璃系统的辐射屏蔽能力。结果表明，含30 wt% Fe2O3的玻璃组合物比其他比例的玻璃组合物具有更好的辐射屏蔽性能。特别是，这些组合物表现出较低的能量吸收累积因子（EABF）、暴露累积因子（EBF）和半值层（HVL）值，从而改善了辐射衰减。此外，它们表现出更高的质量衰减系数（MAC）和线性衰减系数（LAC）值，表明它们在单位质量或单位厚度吸收辐射的有效性增加。此外，含有30 wt% Fe2O3的玻璃显示出更高的有效去除横截面值，增强了其作为伽马和中子辐射屏蔽吸收材料的潜力。这些结果表明了Fe2O3改性玻璃体系在辐射屏蔽技术中的潜在应用。此外，通过分子动力学模拟来确定不同的熔化开始温度：无铁材料为665-1760 K，含铁材料为1024-1846 K。

期刊介绍： Radiation Physics and Chemistry is a multidisciplinary journal that provides a medium for publication of substantial and original papers, reviews, and short communications which focus on research and developments involving ionizing radiation in radiation physics, radiation chemistry and radiation processing. The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. This could include papers that are very similar to previous publications, only with changed target substrates, employed materials, analyzed sites and experimental methods, report results without presenting new insights and/or hypothesis testing, or do not focus on the radiation effects.
