The aim of this investigation is to analyse the radiation shielding features of a SrO–B2O3–TeO2 glass system. The glasses have the composition of 10SrO-(90-X)B2O3-XTeO2, where X is equal to 40, 45, 50, 55, and 60 mol%. The mass attenuation coefficients (MAC) of the samples were experimentally determined and were validated with results obtained using the Phy-X/PSD software. Narrow beam transmission geometry was utilized to obtain the experimental MAC values. When comparing the experimental and theoretical values, the results were found to strongly agree with each other. Using the MAC values, the linear attenuation coefficients (LAC) of the glasses were determined. The results demonstrated that the LAC values decrease with increasing energy, meaning that the glasses are more effective against lower energy photons. The radiation protection efficiency (RPE) showed that increasing the TeO2 content in the glasses improves the shielding ability of the glasses. The HVL and MFP were next calculated and the SBT60 sample showed to have the lowest values at all energies, while having the greatest Zeff and Neff. Lastly, the MFP results for the SBT60 glass were compared against other common radiation shields and it was demonstrated that the sample outperformed most of the shields it was compared against. Therefore, it was concluded that the SBT60 glass has great potential as an environmentally friendly shield for radiation applications.

锶-硼酸-碲酸盐玻璃辐射屏蔽性能的实验与理论分析

本研究的目的是分析 SrO–B 2 O 3 –TeO 2玻璃系统的辐射屏蔽特性。玻璃的组成为 10SrO-(90-X)B 2 O 3 -XTeO 2,其中 X 等于 40、45、50、55 和 60 mol%。样品的质量衰减系数 (MAC) 是通过实验确定的,并通过使用 Phy-X/PSD 软件获得的结果进行验证。窄波束传输几何结构用于获得实验 MAC 值。当比较实验值和理论值时,发现结果彼此非常一致。使用 MAC 值,可以确定眼镜的线性衰减系数 (LAC)。结果表明 LAC 值随着能量的增加而降低,这意味着玻璃对较低能量的光子更有效。辐射防护效率(RPE)表明,增加 TeO 2眼镜中的含量提高了眼镜的屏蔽能力。接下来计算 HVL 和 MFP,SBT60 样品显示在所有能量下都具有最低值,而 Z eff和 N eff最大。最后,将 SBT60 玻璃的 MFP 结果与其他常见的辐射防护罩进行了比较,结果证明该样品的性能优于与之比较的大多数防护罩。因此,得出的结论是,SBT60 玻璃作为辐射应用的环保屏蔽具有巨大的潜力。
