Five glass samples with the composition of 20CdO–10SrO–(70 − x) B2O3xMoO3, where x = 0, 5, 10, 15, and 20 mol%, were analyzed for their radiation shielding properties. The study seeks to observe the effect of increasing the concentration of MoO3 on gamma photon shielding features. The linear attenuation coefficient (LAC) of the fabricated glasses was measured experimentally at five different gamma-ray energies 0.662, 0.184, 0.28, 0.71, and 0.81 MeV. Moreover, the LAC's experimental results of all fabricated glass samples were compared with the Monte Carlo simulation code (MCNP-5) and XCOM program. The measured data and those obtained theoretically using the MCNP-5 code and XCOM program showed strong compatibility. Various parameters were analyzed to determine the glasses' viability as radiation shields, including mass attenuation coefficient, linear attenuation coefficient, radiation protection efficiency, transmission factor, half-value layer, and mean free path. The data were recorded and plotted, and it was determined that the glass coded as MB20 is the most efficient radiation shield out of the investigated samples. The experimental measurements depict that the highest LAC obtained at gamma photon energy 0.184 MeV decreased in the range between 0.557 and 0.894 cm−1, while the lowest obtained at 0.81 MeV and decreased from 0.218 to 0.38 cm−1 for the investigated glass samples MB0 and MB20, respectively.

新型MoO 3掺杂硼酸盐玻璃网络的开发,可用于伽马射线屏蔽应用

分析了五个成分为20CdO–10SrO–(70 − x)B 2 O 3x MoO 3的玻璃样品 的辐射屏蔽性能,其中x = 0、5、10、15和20 mol%。该研究旨在观察增加MoO 3浓度的影响伽马光子屏蔽功能。在五个不同的伽马射线能量0.662、0.184、0.28、0.71和0.81 MeV的条件下,通过实验测量了制成的玻璃的线性衰减系数(LAC)。此外,将LAC对所有玻璃样品的实验结果与蒙特卡罗模拟代码(MCNP-5)和XCOM程序进行了比较。测量数据以及使用MCNP-5代码和XCOM程序从理论上获得的数据显示出强兼容性。分析了各种参数以确定眼镜作为辐射防护屏的可行性,包括质量衰减系数,线性衰减系数,辐射防护效率,透射系数,半值层和平均自由程。记录数据并作图,并且确定编码为MB20的玻璃是所研究样品中最有效的辐射防护屏。实验测量结果表明,在伽马光子能量为0.184 MeV时获得的最高LAC在0.557至0.894 cm之间的范围内降低-1,而所研究的玻璃样品MB0和MB20的最低峰分别为0.81 MeV和从0.218降至0.38 cm -1
