This work aimed to investigate the impact of Lead-fluoride based glasses via theoretical and simulation techniques on mechanical and radiation shielding parameters. Accordingly, Bi₂O₃ was blended with TeO₂–B₂O₃–PbF₂ glasses by using melt-quenching method. Using Fluka Monte Carlo code, the radiation shielding properties have measured. Moreover, Comparatively higher density PbF80 = 6.163 g/cm³ with 80 mol % Bi₂O₃, greater µ, µ_m and Zeff and lower T_1/2, λ, tenth value layer values achieved for TeO₂–B₂O₃– PbF₂/Bi₂O₃ glass pointed it out as the best shield of gamma. Besides, the computed effective removal cross-sections against fast neutrons (Σ_R) observed that the PbF80 sample has commensurately greater with a value 5.2954 (cm⁻¹). The results observed that the variation PbF₂/Bi₂O₃ improves the gamma protection ability of Lead-fluoride based glasses. The incremental of Bi₂O₃ at the expense of PbF₂ increases the density and the packing density of the glasses and hence increase the longitudinal modulus-L, shear modulus-S, bulk modulus-K, and Young's modulus-Y from 15.89 to 25.9 GPa, from 8.49 to 12.09 -GPa, from 4.58 to 9.77 GPa, and from 15.74 to 25.69 GPa, respectively. The increase of the elastic moduli can be attrinuted to the glass former role of Bi₂O₃. The results indicate that the highest PbF₂/Bi₂O₃ ratio encoded PbF00 has the best shielding and mechanical competence with measurable physical properties.

这项工作旨在通过理论和模拟技术研究基于氟化铅的玻璃对机械和辐射屏蔽参数的影响。因此，Bi ₂ O ₃与TeO ₂ –B ₂ O ₃ –PbF ₂玻璃通过熔融淬火法混合。使用 Fluka Monte Carlo 代码，测量了辐射屏蔽特性。此外，相对较高的密度 PbF80 = 6.163 g/cm ³与 80 mol % Bi ₂ O ₃、更大的 µ、µ _m和 Zeff 以及更低的 T _1/2、λ、TeO ₂ –B ₂ O实现的第十层值₃ – PbF ₂ /Bi ₂ O ₃玻璃指出它是伽马的最佳屏蔽。此外，计算出的针对快中子 (Σ _R ) 的有效去除截面观察到，PbF80 样品具有相应更大的值 5.2954 (cm ^-1 )。结果观察到变化PbF ₂ /Bi ₂ O ₃提高了基于氟化铅的玻璃的伽马保护能力。以 PbF ₂为代价增加 Bi ₂ O ₃增加玻璃的密度和堆积密度，从而将纵向模量-L、剪切模量-S、体积模量-K和杨氏模量-Y从15.89增加到25.9 GPa，从8.49增加到12.09-GPa，从4.58增加到分别为 9.77 GPa 和 15.74 至 25.69 GPa。弹性模量的增加可归因于Bi ₂ O ₃的玻璃形成剂作用。结果表明，最高 PbF ₂ /Bi ₂ O ₃比率编码的 PbF00 具有最好的屏蔽和机械性能，并具有可测量的物理特性。
