Abstract

Lead (Pb)-based materials are very effective in radiation shielding due to their high density of Pb. However, they pose health risks to humans because of the toxicity of lead. As a result, the investigation of radiation shielding properties of various lead-free glass materials has drawn a lot of attention from researchers. In this work, the γ radiation competence of the Bi2O3–ZnO–B2O3–SiO2 glass network was investigated, for the first time in the 0.015–15 MeV energy range, using Phy-X/PSD and XCOM software systems. The results showed that 45Bi2O3–5ZnO–20B2O3–30SiO2 glass sample has the highest linear attenuation coefficient, mass attenuation coefficient, and effective atomic number, and it has the lowest half-value layer, tenth-value layer, and mean-free path. Therefore, 45Bi2O3–5ZnO–20B2O3–30SiO sample is more effective on γ ray shielding than 10Bi2O3–40ZnO–20B2O3–30SiO, 20Bi2O3–30ZnO–20B2O3–30SiO, 30Bi2O3–20ZnO–20B2O3–30SiO, and 40Bi2O3–10ZnO–20B2O3–30SiO samples. The comparison of the results with the literature also revealed that the 45Bi2O3–5ZnO–20B2O3–30SiO glass sample is even more effective than some of Bi2O3-based glass systems, which were recently developed in the literature, by at least a factor of 2.
(x)Bi2O3-(0.5 - x)ZnO-0.2B2O3-0.3SiO2 玻璃体系的伽马辐射屏蔽性能
由于铅(Pb)密度高,铅基材料在辐射屏蔽方面非常有效。然而,由于铅的毒性,它们会对人体健康造成危害。因此,研究各种无铅玻璃材料的辐射屏蔽性能引起了研究人员的广泛关注。在这项工作中,利用 Phy-X/PSD 和 XCOM 软件系统首次研究了 Bi2O3-ZnO-B2O3-SiO2 玻璃网络在 0.015-15 MeV 能量范围内的γ 辐射能力。结果表明,45Bi2O3-5ZnO-20B2O3-30SiO2 玻璃样品的线性衰减系数、质量衰减系数和有效原子序数最高,半值层、十值层和平均自由路径最低。因此,45Bi2O3-5ZnO-20B2O3-30SiO 样品比 10Bi2O3-40ZnO-20B2O3-30SiO、20Bi2O3-30ZnO-20B2O3-30SiO、30Bi2O3-20ZnO-20B2O3-30SiO 和 40Bi2O3-10ZnO-20B2O3-30SiO 样品对γ 射线的屏蔽效果更好。将研究结果与文献进行比较后还发现,45Bi2O3-5ZnO-20B2O3-30SiO 玻璃样品甚至比文献中最近开发的一些基于 Bi2O3 的玻璃系统更有效,至少提高了 2 倍。
