某些硼酸盐玻璃的γ衰减参数
Gamma attenuation parameters of some borate glasses
摘要：
在这项研究中，我们已经报道了硼酸盐基玻璃的形式$4(75 - x)B-2O-3 - xBi_2O_3 - 10Na_2O - 10CaO - 5Al_2O_3$（$0 \le x \le 25$摩尔%）的γ射线和中子屏蔽应用，并为此目的，这些玻璃的质量衰减系数进行了研究，使用Geant 4代码和XCOM程序之间的能量范围为1 keV和10 MeV。模拟结果与计算值之间的一个很好的协议。然后利用得到的数值计算其他相关的屏蔽参数，如半值层（HVL），平均自由程（MFP）和有效原子序数（$Z_{\rm eff}$）。还通过使用几何级数（G-P）方法评估了玻璃的曝光累积因子。此外，中子有效去除截面的每一个选定的玻璃已计算。结果表明，玻璃样品中Bi 2 O3的含量影响玻璃的辐射屏蔽性能。可以得出结论，编码为F的玻璃提供了优异的伽马射线屏蔽性能，而编码为D的玻璃在其他样品中提供了更好的中子屏蔽特性。
英文摘要：
In this study we have reported the borate-based glasses in the form of $4(75 - x)B-2O-3 - xBi_2O_3 - 10Na_2O - 10CaO - 5Al_2O_3$ ($0 \le x \le 25$ mol%) for gamma-ray and neutron shielding applications, and for this purpose mass attenuation coefficients of these glasses have been investigated using Geant4 code and XCOM program in the energy range between 1 keV and 10 MeV. A good agreement between the simulation results and computed values was observed. The obtained values were then used to calculate the other related shielding parameters such as half value layer (HVL), mean free path (MFP) and effective atomic numbers ($Z_{\rm eff}$). Exposure buildup factors of the glasses were also evaluated by using the geometrical progression (G-P) method. Additionally, neutron effective removal cross-sections of each selected glass have been computed. The results indicate that the Bi2O3 content in the glass sample affects the radiation shielding properties. It can be concluded that the glass coded as F offers superior gamma-ray shielding properties, while the glass coded as D offers better neutron shielding features among the other samples.
