In this paper, the evaluation of current induced in human the body model exposed to ELF (extremely low frequency) electric and magnetic field generated by a power line is presented. The induced current density in the threedimensional (3D) model human body is obtained by using the Finite element method (FEM).In this paper, the human body is represented by an inhomogeneous model (rotationally-cylindrical body model) composed of several organs of spheroid shape; brain, heart, lungs, liver and intestines. The numerical model was implemented in COMSOL Multiphysics.Index Terms-Human exposure; Extremely low frequency (ELF); Magnetic field; Electric field, Induced current density; quasi-static approximation, Finite element method.I.

“…Note, that according to ICNIRP guidelines from 1998 [2] the current density was a main parameter for the estimation of extremely low frequency exposure effects, while the new ICNIRP guidelines from 2010 [3] propose the induced electric field instead of the induced current. However, there is a substantial amount of results for the current density in the relevant literature for the comparison purposes, e.g., [4][5][6][7][8][9][10][11][12][13]. Several methods have been used to calculate the current density induced in the human body due to exposure to low frequency fields, such as the Finite Difference Time Domain (FDTD) [4,5] the Finite Element Method (FEM) [6][7][8]; the Boundary Element Method (BEM) [9][10]; the impedance method [11] or the Transmission Line (TL) model [12].…”

“…The sensitivity of the induced current density in the body when conductivities of the five internal organs (the brain, heart, lungs, liver and intestines) are taken into account is studied. Figure 1 shows the axisymmetrical and homogeneous geometry of the human body being used by Japanese team [6,7]. The human body model is composed from nine parts (Dimensions are given in centimetres).…”

Abstract-The paper presents an assessment of human exposure to extremely-low-frequency (ELF) electric field generated by a power line using the rotationally-cylindrical body model. The formulation is based on the Laplace type continuity equation. The induced current density in the three-dimensional (3D) model human body is obtained by solving the Laplace equation via the Finite element method (FEM). The main objective is to highlight some parameters influencing the distribution of the induced current density, such as the ohmic contact between the feet and the soil due to the soles of the shoes, and the electrical parameters of the soil. Furthermore, the influence of internal organs (the human model) to the induced current density distribution. The human body is represented by a homogeneous model and also by an inhomogeneous model composed of several organs namely brain, heart, lungs, liver and intestines, whose shapes were spheroid. The proposed model has been validated through comparison to either the experimental results or the theoretical results available in literature being computed by the aid of a homogeneous body model.
