The health effects of weak currents induced in a human body as a result of the interaction between the body and power line electric fields have been investigated. A body model (cylinder + hemisphere) filled with tissues having different conductivities was used to analyze internal current densities. In this analysis, only the magnitudes of the induced current densities were analyzed. In this paper, the finite element method is applied to the analysis of the distributions of the horizontal and vertical currents induced in the cylindrical model. The calculation method was verified by comparing the calculated results with experimental results obtained elsewhere. The basic characteristics of the induced current distributions in the cylindrical model with two tissues having different conductivities have been clarified. © 1998 Scripta Technica.
