Abstract

This study presents a comprehensive examination of the glass systems consisting of TeO₂, ZnO, Bi₂O₃, and Nb₂O₅. The objective is to assess their suitability as radiation shielding materials and analyze their mechanical characteristics. Analysis of TZBN1's mass attenuation coefficients (MAC) was conducted using FLUKA modeling and XCOM. The findings indicated that TZBN1 had the highest Mean Absolute Change (MAC) at low energy levels (0.02 MeV), measured 38.547 cm²/g. These findings suggest that TZBN1 has a more favorable photoelectric effect interaction. Over energies beyond 20 MeV, TZBN4 has exceptional performance in comparison to other samples, with a mass attenuation coefficient (MAC) of 0.043996 cm²/g. These findings suggest an improved capacity to provide protection against high-energy photons. The density of the glass substrates is an essential factor, and TZBN4 exhibits a peak density of 6.15 g/cm³. Consequently, it exhibits a reduced gamma-ray transmission factor (TF), thereby underscoring its efficacy in mitigating gamma radiation. Based on the Makishima and Mackenzie model, TZBN1 exhibits the greatest Young's Modulus, measured at around 814.67 kJ/mol per PD. These findings suggest that TZBN1 exhibits the highest level of mechanical strength and stiffness among the glasses examined. In contrast, TZBN4 exhibits the lowest Young's Modulus of 453.47 kJ/mol per PD, making it potentially appropriate for certain applications that need flexibility. The results underscore the importance of glass chemical composition in tailoring materials for radiation protection and mechanical robustness. The glasses composed of TeO₂, ZnO, Bi₂O₃, and Nb₂O₅, namely TZBN4, are regarded as very promising for applications that need efficient shielding against high-energy photons, while also providing material flexibility and strength. This paper presents a substantial framework for selecting and creating glass materials for the goal of providing safe shielding in the domains of medicine, industry, and nuclear facilities.

详细研究锌、铋和掺铌碲玻璃的机械和伽马射线屏蔽能力

本研究全面考察了由 TeO2、ZnO、Bi2O3 和 Nb2O5 组成的玻璃系统。目的是评估它们作为辐射屏蔽材料的适用性，并分析其机械特性。使用 FLUKA 建模和 XCOM 对 TZBN1 的质量衰减系数 (MAC) 进行了分析。研究结果表明，TZBN1 在低能量水平（0.02 MeV）时的平均绝对变化（MAC）最高，测量值为 38.547 cm2/g。这些发现表明，TZBN1 具有更有利的光电效应相互作用。与其他样品相比，TZBN4 在能量超过 20 MeV 时具有优异的性能，其质量衰减系数 (MAC) 为 0.043996 cm2/g。这些研究结果表明，TZBN4 具有更强的抵御高能光子的能力。玻璃基底的密度是一个重要因素，TZBN4 的峰值密度为 6.15 g/cm³。因此，它的伽马射线透射系数（TF）较低，从而突出了它在减少伽马射线辐射方面的功效。根据 Makishima 和 Mackenzie 模型，TZBN1 的杨氏模量最大，测量值约为 814.67 kJ/mol/PD。这些结果表明，在所研究的玻璃中，TZBN1 具有最高的机械强度和刚度。相比之下，TZBN4 的杨氏模量最低，为 453.47 kJ/mol per PD，因此可能适合某些需要灵活性的应用。研究结果强调了玻璃化学成分在定制材料的辐射防护和机械坚固性方面的重要性。由 TeO2、ZnO、Bi2O3 和 Nb2O5 组成的玻璃，即 TZBN4，被认为在需要有效屏蔽高能光子的应用中非常有前途，同时还能提供材料的灵活性和强度。本文提出了一个选择和创造玻璃材料的实质性框架，目的是在医学、工业和核设施领域提供安全屏蔽。

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.
