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.
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.
