摘要

本文旨在研究 BaO 对 SiO2-B2O3-SrO-ZrO2 辐射衰减的影响。利用 WinXCOM 光子截面数据库计算了玻璃对伽马射线的质量衰减系数（μ/ρ）和其他相关因子。在基本玻璃成分（SiO2-B2O3-SrO-ZrO2）中添加氧化钡（BaO），然后评估其辐射屏蔽能力的增强情况。结果表明，由于不同能量区域的光子相互作用机制不同，伽马衰减能力随着能量的增加而降低。然而，在用氧化钡替代氧化锶的过程中，所研究的玻璃的衰减能力有了显著提高。例如，SiBBSZ3 样品的有效原子序数（Zeff）最高，在 0.015 MeV 时为 46.758，而 BaO 的添加量为 40 摩尔%。因此，可以通过调整构成玻璃氧化物（如 BaO 和 SrO）的相对浓度来定制衰减特性。此外，所研究的玻璃的屏蔽性能超过了许多传统混凝土和最近开发的玻璃，显示了其在辐射屏蔽方面的潜力。这些结果可能有助于利用丰富的原材料开发出有效且低成本的辐射屏蔽玻璃成分。

Influence of BaO addition on gamma attenuation and radiation shielding performance of SiO2-B2O3-SrO-ZrO2 glasses

The present research paper aims to investigate the influence of BaO on the radiation attenuation of SiO₂-B₂O₃-SrO-ZrO₂. The mass attenuation coefficient (μ/ρ) and the other related factors of the glasses for gamma-rays are calculated using the WinXCOM photon cross section database. Barium oxide (BaO) is added to the base glass composition, SiO₂-B₂O₃-SrO-ZrO₂, and then the enhancement of its radiation shielding capabilities is assessed. The results showcased that the gamma attenuation ability decrease as energy increases due to the different mechanisms of photon interactions at various energy regions. However, there is a significant increase in the attenuation competence of the studied glasses during the substitution of SrO oxide by BaO. For example, the highest effective atomic number (Z_eff) is observed for the SiBBSZ3 sample, with the addition of 40 BaO mol%, with the value of 46.758 at 0.015 MeV. Therefore, the attenuation properties can be tailored by adjusting the relative concentrations of the constituting glass oxides such as BaO and SrO. Furthermore, the shielding properties of the studied glasses surpass those of numerous conventional concretes and recently developed glasses, showcasing its potential in radiation shielding. Such obtained results may help to develop effective and low-cost radiation shielding glass compositions based on abundantly available raw materials.
