The demand for more materials for efficient shielding of radiation has been on the rise day by day due to some witnessed progress in applications of radiations in science and technology. In this research, we investigated the gamma ray shielding capacity of zinc boro-aluminosilicate (ZBASi) glass by varying concentrations of B2O3. Fundamentally, experimental and theoretical means were both adopted to evaluate photon shielding characteristics of the studied glasses. Additionally, amorphous nature and crystalline sizes of the glass sample were determined using XRD technique and Debye Scherrer equation respectively. The results show that as the B2O3 content increased from 55 to 70 wt %, the optical bandgap, and packing density decreased. However, the density, and molar volume were found to increase accordingly. Using Phy-x/PSD and genat4, the maximum values of mass attenuation coefficient (MAC) for ZBASi-4, ZBASi-3, ZBASi-2, and ZBASi-1 were found to be 20.2, 17.5, 16.3, and 9.6 cm2/g at 20 KeV, respectively. With respect to exposure rate, the exposure buildup factor (EBF) is low in the region where density is high, meaning that photon attenuation power is high in the region of low EFB (high density). The production of aluminosilicate glass poses fewer environmental risks than that of traditional lead-based shielding materials. It is therefore a more environmentally friendly option since harmful heavy metals are not involved.

用于红外和 γ 传感应用的硼铝硅酸锌玻璃：物理特性和 γ 射线衰减方面


由于见证了辐射在科学技术中的应用取得一些进展，对更多有效屏蔽辐射的材料的需求日益增加。在这项研究中，我们研究了不同浓度的 B2O3 硼铝硅酸盐锌 （ZBASi） 玻璃的伽马射线屏蔽能力。从根本上说，采用实验和理论手段来评估所研究玻璃的光子屏蔽特性。此外，使用 XRD 技术和 Debye Scherrer 方程分别测定了玻璃样品的无定形性质和晶体尺寸。结果表明，随着 B2O3 含量从 55 wt % 增加到 70 wt %，光学带隙和堆积密度降低。然而，发现密度和摩尔体积相应地增加。使用 Phy-x/PSD 和 genat4 发现 ZBASi-4、ZBASi-3、ZBASi-2 和 ZBASi-1 在 20 KeV 下的质量衰减系数 （MAC） 最大值分别为 20.2、17.5、16.3 和 9.6 cm2/g。就曝光率而言，在密度高的区域，曝光累积因子 （EBF） 较低，这意味着在低 EFB（高密度）区域，光子衰减功率较高。与传统的铅基屏蔽材料相比，铝硅酸盐玻璃的生产对环境构成的风险更小。因此，由于不涉及有害的重金属，因此这是一种更环保的选择。
