Abstract

The present study aims at examining the low-energy radiation shielding properties of a Bi₂O₃- and ZnO-doped borosilicate [(61-x) B₂O₃–10ZnO–10BaO–5TiO₂-(14+x) Bi₂O₃; x = 4, 8, 12, and 16 mol%] glass system. The mechanical characteristics of the produced glasses were evaluated using the Makishima–Mackenzie theory. The study shows that substituting part of B₂O₃ with Bi₂O₃ reduces the microhardness and mechanical moduli of the glasses.

Additionally, radiation shielding factors were determined to investigate the relationship between Bi₂O₃ and B₂O₃ content and the glasses' low-energy gamma-ray shielding performance, as well as the influence of the radiation source energy on the glass properties. The results demonstrated a positive correlation between increasing Bi₂O₃ concentration and the linear attenuation coefficients (LAC) of the glasses.

The glass sample containing 18 mol% Bi₂O₃ led to the lowest LAC values, whereas the sample with 30 mol% Bi₂O₃ led to the highest. Furthermore, the mean free path (MFP) of the glasses was compared to that of commercial glasses to assess their effectiveness in low-energy radiation protection. The glass with the highest Bi₂O₃ content had the lowest MFP and thus provided better protection than some commercial alternatives.

多组分掺杂硼酸盐玻璃的低能量有效屏蔽设计与评价

本研究旨在研究Bi2O3-和zno掺杂的硼硅酸盐[(61-x) B2O3-10ZnO-10BaO-5TiO2 -(14+x) Bi2O3]的低能辐射屏蔽性能；X = 4、8、12和16 mol%]玻璃体系。利用Makishima-Mackenzie理论对所制玻璃的力学特性进行了评价。研究表明，用Bi2O3代替部分B2O3降低了玻璃的显微硬度和力学模量。测定辐射屏蔽系数，研究Bi2O3和B2O3含量与玻璃低能γ射线屏蔽性能的关系，以及辐射源能量对玻璃性能的影响。结果表明，Bi2O3浓度的增加与玻璃的线性衰减系数（LAC）呈正相关。含有18 mol% Bi2O3的玻璃样品的LAC值最低，而含有30 mol% Bi2O3的样品的LAC值最高。此外，将该玻璃的平均自由程（MFP）与商用玻璃进行了比较，以评估其在低能辐射防护中的有效性。Bi2O3含量最高的玻璃具有最低的MFP，因此比一些商业替代品提供更好的保护。

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.
