This study examined the radiation shielding features of ball clay-cement-iron slag as an alternative to concrete. Using a variety of cement, ball clay, and iron slag compositions, six samples were fabricated. The linear attenuation coefficient (LAC) was experimentally reported using three point sources (Am-241, Cs-137and Co-60) and a HPGe detector. The results show that the LACExp and LACXCOM values for the ball clay-cement-iron slag composites harmonized well. For the composite, the difference between the LAC values for the composite, 0.06 MeV, is notable; at the same time, they are almost negligible at 0.662 and 1.173 MeV. At 0.06 MeV, the difference between the LAC, from C1 and C6 is 0.56; yet, it is only 0.017 and 0.013 at 0.662 and 1.173 MeV. The LAC results confirm that adding iron slag to the prepared composites has a positive impact on their radiation attenuation competence. The composite's half value layer (HVL) at 0.06 MeV is reduced by about half when the iron slag content changes by 50 w.t%. According to the HVL results, the current alteration to iron slag contents reduces the influence of gamma photons.

用实验和理论方法研究球粘土-水泥-铁渣复合材料的辐射衰减特性

这项研究检查了球粘土-水泥-铁渣作为混凝土替代品的辐射屏蔽特性。使用各种水泥、球粘土和铁渣成分,制造了六个样品。使用三点源(Am-241、Cs-137 和 Co-60)和 HPGe 检测器实验报告了线性衰减系数 (LAC)。结果表明,LAC Exp和 LAC XCOM球粘土-水泥-铁渣复合材料的值协调良好。对于复合材料,复合材料的 LAC 值之间的差异 0.06 MeV 是显着的;同时,它们在 0.662 和 1.173 MeV 时几乎可以忽略不计。在 0.06 MeV 时,LAC 与 C1 和 C6 之间的差异为 0.56;然而,在 0.662 和 1.173 MeV 时它只有 0.017 和 0.013。LAC 结果证实,向制备的复合材料中添加铁渣对其辐射衰减能力具有积极影响。当铁渣含量变化 50 wt% 时,复合材料的 0.06 MeV 半值层 (HVL) 减少了大约一半。根据 HVL 结果,当前对铁渣含量的改变降低了伽马光子的影响。
