Abstract

The present study explores the radiation shielding investigations on Alkaline-earth (AE) incorporated Bismuth telluro-borate glasses prepared following the melt quenching process. A series of pristine quintet glasses with different oxide(s) and fluoride(s) modifiers were prepared with the glass composition (in wt%) of 64B2O3+20Bi2O3+15TeO2+1Eu2O3 & 49B2O3 +20Bi2O3+ 15TeO2 +15M+1Eu2O3 (where M= SrF, SrO, BaF and BaO). XRD, FTIR, UV-Vis-NIR spectroscopy and Phys-X software have been used to examine the impact of modifiers on the structural and shielding properties. The XRD pattern confirms the glassy character of the samples, whereas the FTIR analysis explore the interior structural unit changes. The physical and structural traits of the glasses were successfully estimated, thus reveal the nature of the glass, including the presence of BOs and NBOs. Additionally, elastic properties were calculated to assess the suitability of the samples as promising materials for attenuation. The radiation shielding performance for the prepared glasses is estimated employing the Phys-X software. Additionally, the calculated shielding performance was affirmed by the Monte Carlo simulation method over the energy interval of 0.015–15 MeV. The evaluation shows the high shielding performance of the prepared glasses compared to the commercial radiation-protective lead-based glasses supplied by Schott AG. Among the prepared glasses, BaO modifier incorporated Bismuth telluro-borate glasses exhibit higher LAC (1.929 cm−1 at 0.2 MeV), Zeq (51.317–28.456 at 1.5–15 Mev). It also has lower EBF (53.228 at 2 MeV), and EABF (59.268 at 2 MeV) signifying the enhanced capability of radiation attenuation behavior hence BBTE:BaO glass is optimum for multifunctional shielding applications.
用于先进多功能屏蔽应用的碱土改性碲硼酸铋玻璃
本文对熔融淬火法制备的含碱土碲硼酸铋玻璃的辐射屏蔽性能进行了研究。以64B2O3+20Bi2O3+15TeO2+1Eu2O3 &的玻璃组成(wt%)制备了一系列具有不同氧化物和氟化物改性剂的原始五元玻璃;49B2O3 +20Bi2O3+ 15TeO2 +15M+1Eu2O3(其中M= SrF, SrO, BaF和BaO)。利用XRD、FTIR、UV-Vis-NIR光谱和physx软件研究了改性剂对结构和屏蔽性能的影响。XRD分析证实了样品的玻璃化特征,而FTIR分析则揭示了样品内部结构单元的变化。成功地估计了玻璃的物理和结构特征,从而揭示了玻璃的性质,包括BOs和NBOs的存在。此外,还计算了弹性性能,以评估样品作为有希望的衰减材料的适用性。利用物理- x软件对制备的玻璃的辐射屏蔽性能进行了估计。在0.015 ~ 15 MeV的能量区间内,用蒙特卡罗模拟方法验证了所计算的屏蔽性能。评价结果表明,与Schott AG公司提供的商用防辐射铅基玻璃相比,制备的玻璃具有较高的屏蔽性能。采用BaO改性剂的碲硼酸铋玻璃具有较高的LAC (0.2 MeV时为1.929 cm−1)和Zeq (1.5 ~ 15 MeV时为51.317 ~ 28.456)。它还具有较低的EBF (2 MeV时为53.228)和EABF (2 MeV时为59.268),表明辐射衰减行为的能力增强,因此BBTE:BaO玻璃是多功能屏蔽应用的最佳选择。

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.
