The search for lead-free radiation shielding materials has become a matter of great demand, especially with the increase in the use of ionizing radiation, including X-rays and γ-rays, in various vital fields. In the present work, the shielding potential against γ-radiation of lead-free (Cu–Ba–Y–O)-x(Zn–Fe–O) samples ( = 0.1–2.0 wt%) was evaluated. The samples are polycrystals and showed an orthorhombic crystal structure. The orthorhombicity was progressively reduced with the effect of Zn–Fe–O addition. The introduction of Zn–Fe–O into Cu–Ba–Y–O altered also the density values of the samples. The density values followed the order = 2.0 < = 1.0 < = 0.5 < = 0.1 wt%. The structural, and physical properties results were correlated with radiation shielding properties. The shielding efficiency against γ-radiation of different proposed ceramics was evaluated using Monte Carlo Simulation. The analysis revealed that the introduction of Zn–Fe–O into Cu–Ba–Y–O decreases the linear attenuation coefficient of the samples. The Linear attenuation coefficient over the γ-ray energy interval between 0.015 and 2.506 MeV varied between 322.560 and 0.243 cm, 322.41–0.243 cm, 290.799–0.220 cm, and 263.769–0.199 cm for x = 0.1, 0.5, 1.0, and 2.0 wt%, respectively.

(Cu-Ba-Y-O)-x(Zn-Fe-O)陶瓷的γ辐射屏蔽性能研究


寻找无铅辐射屏蔽材料已成为一个巨大的需求，特别是随着电离辐射（包括 X 射线和 γ 射线）在各个重要领域的使用增加。在目前的工作中，评估了无铅 (Cu-Ba-Y-O)-x(Zn-Fe-O) 样品 (= 0.1-2.0 wt%) 的 γ 辐射屏蔽潜力。样品是多晶并显示出斜方晶体结构。随着 Zn-Fe-O 添加的影响，正交性逐渐降低。将 Zn-Fe-O 引入到 Cu-Ba-Y-O 中也改变了样品的密度值。密度值遵循以下顺序 = 2.0 < = 1.0 < = 0.5 < = 0.1 wt%。结构和物理性能结果与辐射屏蔽性能相关。使用蒙特卡罗模拟评估了不同陶瓷的 γ 辐射屏蔽效率。分析表明，Cu-Ba-Y-O中引入Zn-Fe-O降低了样品的线性衰减系数。对于 x = 0.1、0.5、1.0 和 2.0 wt，γ 射线能量区间在 0.015 和 2.506 MeV 之间的线性衰减系数在 322.560 和 0.243 cm、322.41–0.243 cm、290.799–0.220 cm 和 263.769–0.199 cm 之间变化％， 分别。
