Abstract

This study examined the physical and radiation shielding properties of compounds formed by adding 0–50 wt % Bi₂O₃ to blast furnace slag. Physical properties: density included molar volume, oxygen molar volume, and oxygen packing density were calculated. The radiation protection properties of the prepared glasses were calculated theoretically using Phy-X/PSD software. Experimental shielding measurements were also made at some energy levels to verify the shielding values. The addition of Bi₂O₃ increased the composition density from 2.87 to 4.54 g/cm³. Mass attenuation coefficient (MAC) results showed increased radiation shielding performance with adding Bi₂O₃. While the highest MAC value for the pure composition was 1.222 cm²/g, the lowest was calculated as 0.054 cm²/g for the sample with 50% Bi₂O₃ added by weight. In addition, effective atomic charge (Z_eff) and electron densities (N_eff) were also determined, and it was observed that these values increased significantly with the addition of Bi₂O₃. Fast neutron removal cross-section values of the compositions were determined and compared with some commercial/alternative shielding materials.

高炉渣是否适合生产防辐射玻璃？

本研究考察了在高炉炉渣中添加0-50 wt % Bi2O3形成的化合物的物理和辐射屏蔽性能。物理性质：密度包括摩尔体积、氧摩尔体积、氧堆积密度计算。利用Phy-X/PSD软件对所制备玻璃的辐射防护性能进行了理论计算。在一些能级上进行了实验屏蔽测量，以验证屏蔽值。Bi2O3的加入使组成密度由2.87 g/cm3增加到4.54 g/cm3。质量衰减系数（MAC）结果表明，Bi2O3的加入提高了材料的辐射屏蔽性能。纯组分的最高MAC值为1.222 cm2/g，而按重量添加50% Bi2O3的样品的最低MAC值为0.054 cm2/g。此外，还测定了有效原子电荷（Zeff）和电子密度（Neff），并观察到这些值随着Bi2O3的加入而显著增加。测定了这些成分的快中子去除截面值，并与一些商用/替代屏蔽材料进行了比较。

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.
