This study aims to perform multidirectional characterizations on nuclear shielding efficiencies on some bismuth-based glasses. Accordingly, the γattenuation coefficients for xBi₂O₃-(75-x)B₂O₃−25Li₂O (x= 0, 10, 20, 30, 40, 50, 60 the 70 mol%) were widely evaluated using simulations and theoretical methods. Linear attenuation coefficient (LAC) of the glasses was obtained by the Monte Carlo general-purpose simulation code FLUKA and compared with the XCOM database up to 15 MeV. Moreover, LAC values have been utilized to evaluate related parameters like mass attenuation coefficient (MAC), total molecular cross-section (σ_t), total atomic cross-section (σ_a), half-value layer (HVL), total electronic cross-section (σ_e), mean free path (MFP), effective atomic number (Z_eff), and effective electron density (N_eff). The results noted that the XCOM and FLUKA data of the shielding parameters are in great agreement. Relatively higher density (5.818 g/cm³), greater LAC, MAC, Zeff, and lower HVL, MFP values are achieved for 70Bi₂O₃-5B₂O₃−25Li₂O glass. Accordingly, this glass sample is a better gamma shield.

这项研究旨在对某些铋基玻璃的核屏蔽效率进行多方向表征。因此，使用模拟广泛评估了xBi ₂ O _3-（75-x）B ₂ O ₃ -25Li ₂ O（x = 0，10，20，30，40，50，60 the 70 mol％）的γ衰减系数。和理论方法。眼镜的线性衰减系数（LAC）是通过Monte Carlo通用仿真代码FLUKA获得的，并与XCOM数据库进行了比较，直到15 MeV。此外，LAC值已被用来评估相关参数等质量衰减系数（MAC），总分子量的横截面（σ_吨），总原子横截面（σ_一个），半值层（HVL），总电子的横截面（σ _ë），平均自由程（MFP），有效原子序数（Z _EFF），和有效的电子密度（N _EFF）。结果表明，XCOM和FLUKA的屏蔽参数数据非常吻合。相对较高的密度（5.818克/厘米³），大于LAC，MAC，泽夫，并降低HVL，MFP值是针对70Bi实现₂ ö ₃ -5B ₂ ö ₃ -25Li ₂ O系列玻璃。因此，该玻璃样品是更好的伽马屏蔽。
