In this study, several radiation shielding characteristics of Bi2O3 modified Lithium Zinc Silicate glass systems were reported using the Phy-X program. The mass attenuation coefficient (MAC) demonstrates a substantial energy dependency only at low energy range (0.284 MeV < E < 0.662 MeV), however it exhibits a slight energy dependency at high energies. It was shown that the transmission factor (TF) increases with energy, suggesting that at higher energies, more gamma rays can pass through the lithium zinc Silicate glasses. We reported the transmission factor (TF) at different thicknesses and we found that the TF at 0.347 MeV for Li25Bi0 varies between 0.92 and 0.77 for thicknesses of 0.3 and 0.9 cm respectively. Also, Li5Bi20's TF is lower than Li25Bi0's, which means that the effectiveness of the samples as shields will increase with the quantity of Bi2O3 present. The TVL is decreased by the introduction of Bi2O3, with Li5Bi20 possessing the smallest TVL and being regarded as the superior absorber. The lowest TVL recorded for selected glasses are 7.608, 3.189, 2.188, 1.677 and 1.427 cm for Li25Bi0 to Li5Bi20 respectively. The TVL results showed that at 0.284 MeV, the TVL for the Li25Bi0 is 5.33 times the TVL of Li5Bi20. At 0.347 MeV, the TVL of Li25Bi0 is 4.08 times the TVL of Li5Bi20, while at 0.662 MeV the TVL of Li25Bi0 is 2.36 times the TVL of Li5Bi20. We compared the effective atomic number (Zeff) for the selected glasses with other materials and we found that all these glasses have higher Zeff than ordinary concrete, and RS-253-G18, except Li25Bi0 sample which shows lower Zeff than RS-253-G18.

Bi2O3改性硅酸锂锌玻璃体系的辐射屏蔽特性研究


在这项研究中，使用 Phy-X 程序报道了 Bi2O3 改性硅酸锂锌玻璃系统的几种辐射屏蔽特性。质量衰减系数 （MAC） 仅在低能量范围 （0.284 MeV < E < 0.662 MeV） 表现出很大的能量依赖性，但在高能量下表现出轻微的能量依赖性。结果表明，透射因子 （TF） 随着能量的增加而增加，这表明在更高的能量下，更多的伽马射线可以穿过硅酸锌锂玻璃。我们报告了不同厚度的透射因子 （TF），我们发现 Li25Bi0 在 0.347 MeV 时的 TF 分别在 0.92 和 0.77 cm 厚度的 0.92 和 0.77 之间变化。此外，Li5Bi20 的 TF 低于 Li25Bi0，这意味着样品作为屏蔽的有效性会随着 Bi2O3 的含量而增加。引入 Bi2O3 降低了 TVL，其中 Li5Bi20 具有最小的 TVL，被认为是优越的吸收剂。Li25Bi0 至 Li5Bi20 的最低 TVL 分别为 7.608、3.189、2.188、1.677 和 1.427 厘米。TVL 结果表明，在 0.284 MeV 时，Li25Bi0 的 TVL 是 Li5Bi20 TVL 的 5.33 倍。在 0.347 MeV 时，Li25Bi0 的 TVL 是 Li5Bi20 TVL 的 4.08 倍，而在 0.662 MeV 时，Li25Bi0 的 TVL 是 Li5Bi20 TVL 的 2.36 倍。我们将所选玻璃的有效原子序数 （Zeff） 与其他材料进行了比较，发现所有这些玻璃的 Zeff 都高于普通混凝土和 RS-253-G18，但 Li25Bi0 样品的 Zeff 低于 RS-253-G18。
