Abstract

New glasses with enhanced radiation shielding characteristics have potential applications in different fields requiring radiation protection. In the context of radiation shielding applications, this work aims to develop new lead-free B2O3–TeO2–Bi2O3–ZnO–CaO glass systems. A 15–30 mol% increase in TeO2 concentration results in a 4.070–4.498 g/cm3 density increase. The influence of increasing the TeO2 doping concentration on the mechanical properties of the prepared boro-tellurite glass was utilized using the Makishima-Makinze theory. Additionally, the influence of raising the TeO2 concentration on the radiation shielding properties of the prepared boro-tellurite glass was studied using the Monte Carlo simulation. The Monte Carlo simulation confirms that a 15–30 mol% TeO2 increase enhances LAC values, reducing half-value layer thickness (HVL), and improving radiation shielding. However, mechanical properties such as hardness and Young's modulus slightly decrease due to TeO2 substitution.

TeO2：作为提高b2o3基玻璃体系辐射屏蔽性能的关键成分

具有增强辐射屏蔽特性的新型玻璃在需要辐射防护的不同领域具有潜在的应用前景。在辐射屏蔽应用的背景下，本工作旨在开发新的无铅B2O3-TeO2-Bi2O3-ZnO-CaO玻璃体系。当TeO2浓度增加15-30 mol%时，密度增加4.070-4.498 g/cm3。利用Makishima-Makinze理论分析了TeO2掺杂浓度的增加对硼碲玻璃力学性能的影响。此外，利用蒙特卡罗模拟研究了提高TeO2浓度对制备的硼碲酸盐玻璃辐射屏蔽性能的影响。蒙特卡罗模拟证实，增加15-30 mol%的TeO2可以提高LAC值，减少半值层厚度（HVL），并改善辐射屏蔽。然而，由于TeO2取代，硬度和杨氏模量等力学性能略有下降。

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.
