This paper examines radiation-shielding abilities of oxyfluoro-tellurite-zinc glasses in the chemical form of AlF3–TeO2–ZnO under the substitution of AlF3 by ZnO. Gamma-ray- and neutron-shielding properties were tested in terms of mass attenuation coefficient (μ/ρ), half value layer, mean free path, effective atomic numbers (Zeff), effective electron density (Neff) and removal cross-section (ΣR). The μ/ρ values of the glasses were generated by Geant4 simulations over an extended energy range and then the generated data were confirmed via XCOM software. The results showed that both gamma-ray- and neutron-shielding efficiencies of the selected glasses evolved by substituting of AlF3 by ZnO. Nuclear radiation-shielding abilities of the current glass systems were compared with that of some conventional shielding materials and newly developed HMO glasses. It can be concluded that oxyfluoro-tellurite-zinc glasses could be useful to design novel shields for radiation protection applications.

氧氟-亚碲酸盐-锌玻璃及ZnO替代AlF3下的核屏蔽能力

本文研究了在用 ZnO 取代 AlF3 的情况下,化学形式为 AlF3-TeO2-ZnO 的氧氟-碲酸盐-锌玻璃的辐射屏蔽能力。在质量衰减系数 (μ/ρ)、半值层、平均自由程、有效原子序数 (Zeff)、有效电子密度 (Neff) 和去除截面 ( ΣR)。玻璃的 μ/ρ 值是通过 Geant4 模拟在扩展的能量范围内生成的,然后通过 XCOM 软件确认生成的数据。结果表明,所选玻璃的伽马射线和中子屏蔽效率都是通过用 ZnO 代替 AlF3 来提高的。将现有玻璃系统的核辐射屏蔽能力与一些传统屏蔽材料和新开发的 HMO 玻璃的核辐射屏蔽能力进行了比较。可以得出结论,氧氟-亚碲酸盐-锌玻璃可用于设计用于辐射防护应用的新型屏蔽。
