Non-ionizing dosimetry investigations of extremely low frequency (ELF) magnetic fields that are generated by underground power cables as well as the minimization of their health effects are significant topics handled by numerous researchers. In this study, ELF magnetic fields and current densities caused by three-phased underground transmission lines induced in the human model were examined utilizing both analytical and numerical methods. Analyses were carried out using a two-dimensional problem scenario for the comprehensive head and body model. The results of the finite element method (FEM)-based simulation studies and the analytical calculations are consistent with each other. Moreover, a magnetic field shielding method utilizing conductive material was presented in the study. The shielding technique performed with copper material was carried out to mitigate the magnetic field and possible dosimetry hazards in the ELF region. The proposed shield was a 4-mm reverse U-shaped copper material.

由地下电缆产生的极低频 (ELF) 磁场的非电离剂量学研究以及最小化其对健康的影响是众多研究人员处理的重要课题。在这项研究中，利用分析和数值方法检查了人体模型中感应的三相地下传输线引起的 ELF 磁场和电流密度。使用二维问题场景对综合头部和身体模型进行分析。基于有限元法 (FEM) 的模拟研究和解析计算的结果彼此一致。此外，该研究还提出了一种利用导电材料的磁场屏蔽方法。使用铜材料执行的屏蔽技术是为了减轻 ELF 区域中的磁场和可能的剂量学危害。建议的屏蔽是一种 4 毫米的倒 U 形铜材料。
