Abstract

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.

用于红外和伽马传感应用的硼铝硅酸锌玻璃：物理特性和伽马射线衰减方面的问题

由于辐射在科技领域的应用取得了一些有目共睹的进展，对更多有效屏蔽辐射的材料的需求与日俱增。在这项研究中，我们研究了不同浓度的 B2O3 对硼铝硅酸锌（ZBASi）玻璃的伽马射线屏蔽能力。从根本上说，我们采用了实验和理论两种方法来评估所研究玻璃的光子屏蔽特性。此外，还利用 XRD 技术和 Debye Scherrer 方程分别测定了玻璃样品的无定形性质和结晶尺寸。结果表明，随着 B2O3 含量从 55 wt % 增加到 70 wt %，光带隙和堆积密度都有所下降。然而，密度和摩尔体积却相应增加。使用 Phy-x/PSD 和 genat4，发现 ZBASi-4、ZBASi-3、ZBASi-2 和 ZBASi-1 在 20 KeV 时的质量衰减系数 (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，曝光堆积因子（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，硅酸铝玻璃的生产对环境造成的风险更小。因此，由于不涉及有害重金属，它是一种更环保的选择。

期刊介绍： Radiation Physics and Chemistry is a multidisciplinary journal that provides a medium for publication of substantial and original papers, reviews, and short communications which focus on research and developments involving ionizing radiation in radiation physics, radiation chemistry and radiation processing. The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. This could include papers that are very similar to previous publications, only with changed target substrates, employed materials, analyzed sites and experimental methods, report results without presenting new insights and/or hypothesis testing, or do not focus on the radiation effects.
