Hydroxyapatite (HAP) bio-composites play a prominent role in addressing the reparative and replacement needs of human bone and dental tissues. Despite the suboptimal mechanical characteristics inherent in pure HAP, strength and durability enhancements have been achieved by incorporating various alloys and materials. The provided study delves into the radiation shielding and mechanical attributes of Fe2O3-reinforced HAP composites intended for use as implants, featuring Fe2O3 concentrations at 0.0, 2.5, 5.0, and 7.5 wt%. In addition, by leveraging the robust FLUKA Monte Carlo simulation code, the study explores the composites' response to the magnetic field. The findings suggest that augmenting the Fe2O3 content improves radiation shielding and mechanical properties in the chosen samples. Furthermore, in the absence of a magnetic field, the particles' spatial distribution (contour curves) exhibits symmetry along the X-axis. Nonetheless, a discernible pattern becomes apparent upon exposure to a magnetic field of Bx = 5 micro Tesla. The data extracted from this article can be used for medical and therapeutic applications and subsequent studies.

利用 Fe2O3 改进 HAP 复合材料：研究辐射屏蔽、机械属性和磁场效应


羟基磷灰石 （HAP） 生物复合材料在满足人体骨骼和牙齿组织的修复和替代需求方面发挥着重要作用。尽管纯 HAP 固有的机械特性不理想，但通过采用各种合金和材料，已经实现了强度和耐用性的增强。所提供的研究深入探讨了用作植入物的 Fe2O3 增强 HAP 复合材料的辐射屏蔽和机械属性，其 Fe2O3 浓度为 0.0、2.5、5.0 和 7.5 wt%。此外，通过利用强大的 FLUKA Monte Carlo 仿真代码，该研究探索了复合材料对磁场的响应。研究结果表明，增加 Fe2O3 含量可以改善所选样品的辐射屏蔽和机械性能。此外，在没有磁场的情况下，粒子的空间分布（等值线曲线）沿 X 轴表现出对称性。尽管如此，当暴露于 Bx = 5 微特斯拉的磁场时，可辨别的模式变得明显。从本文中提取的数据可用于医学和治疗应用以及后续研究。
