Abstract In this study, mechanical and nuclear radiation shielding behaviors of highly efficient alkaline phosphate glasses with various GeO2 concentrations were evaluated for their nuclear radiation shielding applications. Moreover, the glass rigidity parameters of alkaline phosphate glasses were calculated for determination mechanical properties. The μm values were calculated using XCOM program and MCNPX simulation code. The nuclear radiation shielding properties (gamma and neutron) such as μm, HVL, TVL, MFP, Zeff, EBF, EABF, and ΣR were calculated for all alkaline phosphate glasses with various GeO2 concentrations. The results showed that μm, Zeff, and ΣR increased as the Bi2O3 concentration increased. The G14 glass sample had the minimum HVL, TVL, MFP, EBF and EABF. The G14 sample had the largest μm, Zeff, and the number of network bonds, and can be considered as an excellent attenuator for gamma and neutron shielding. The outcomes of recent investigation can be useful to understand the nature of GeO2 additive into alkaline phosphate glasses, which can be considered as a candidate shield type in medical and industrial radiation facilities.

碱性磷酸盐玻璃和氧化锗 (GeO2) 添加剂的协同作用：机械和核辐射屏蔽行为

摘要 在这项研究中，评估了具有不同 GeO2 浓度的高效碱性磷酸盐玻璃的机械和核辐射屏蔽性能，以用于其核辐射屏蔽应用。此外，还计算了碱性磷酸盐玻璃的玻璃刚度参数以确定机械性能。μm 值使用 XCOM 程序和 MCNPX 模拟代码计算。计算了各种 GeO2 浓度的所有碱性磷酸盐玻璃的核辐射屏蔽特性（γ 和中子），例如 μm、HVL、TVL、MFP、Zeff、EBF、EABF 和 ΣR。结果表明，随着 Bi2O3 浓度的增加，μm、Zeff 和 ΣR 增加。G14 玻璃样品具有最小的 HVL、TVL、MFP、EBF 和 EABF。G14 样品具有最大的 μm、Zeff 和网络键数，并且可以被认为是伽马和中子屏蔽的优秀衰减器。最近的调查结果有助于了解 GeO2 添加剂在碱性磷酸盐玻璃中的性质，可将其视为医疗和工业辐射设施中的候选屏蔽类型。
