In the present investigation, nuclear radiation shielding parameters of xTeO2 + (100–x)Li2O (where x = 95, 90, 85, 80, 75, and 70 mol%) glass system have been examined. Gamma shielding parameters such as mass attenuation coefficients (MAC), half-value layer (HVL), tenth-value layer (TVL), mean free path (MFP), effective atomic number (Zeff), effective electron density (Neff) were calculated. Moreover, neutron effective cross sections (∑R) are determined. The calculations for present materials have been performed in different photon energy ranges (0.01–20 MeV) and using Monte Carlo N-Particle eXtended (MCNPX) simulation code and theoretical results were also obtained with WinXcom program. The results obtained from the MCNPX and WinXcom program were found to be in well harmony. Moreover, for the assessment of radiation shielding success of tellurite glasses, the mass stopping power (MSP) and projected range (PR) were computed for proton and alpha particles using stopping and range of ions in matter (SRIM) code. When the results obtained from the study are examined, it is seen that 95TeLi glass has the lowest HVL, TVL, MFP, TF and the highest (∑R) values. Therefore, the 95TeLi glass has the most perfect radiation shielding achievement than other investigated glasses.

xTeO2+(100-x)Li2O玻璃体系核辐射屏蔽性能对比评价

在本研究中,已检查 xTeO2 + (100–x)Li2O(其中 x = 95、90、85、80、75 和 70 mol%)玻璃系统的核辐射屏蔽参数。计算了质量衰减系数(MAC)、半值层(HVL)、第十值层(TVL)、平均自由程(MFP)、有效原子序数(Zeff)、有效电子密度(Neff)等伽马屏蔽参数. 此外,还确定了中子有效截面 (∑R)。目前材料的计算已在不同的光子能量范围 (0.01-20 MeV) 下进行,并使用 Monte Carlo N-Particle eXtended (MCNPX) 模拟代码,也使用 WinXcom 程序获得了理论结果。发现从 MCNPX 和 WinXcom 程序获得的结果非常协调。而且,为了评估亚碲酸盐玻璃的辐射屏蔽成功率,使用停止和物质离子射程 (SRIM) 代码计算质子和 α 粒子的质量停止本领 (MSP) 和投影范围 (PR)。当检查从研究中获得的结果时,可以看出 95TeLi 玻璃具有最低的 HVL、TVL、MFP、TF 和最高的 (∑R) 值。因此,95TeLi 玻璃比其他被研究的玻璃具有最完美的辐射屏蔽性能。
