Abstract

A finite element method (FEM) with nonuniform mesh is employed for the calculation of extremely low frequency (ELF) currents induced in a human body by a global system for mobile communications (GSM) phone. The magnetic field of the phone is measured, and an equivalent source with magnetic dipoles is constructed for the numerical simulation. A cell of variable size is used in the simulation to accurately model the most important areas of the body model, namely areas close to the source and parts of the central nervous system. Three different mobile phone positions are considered: normal operation on the side of the head, breast pocket, and the small of the back where the spinal cord is close to the phone. Obtained results are compared with the guidelines of the International Commission on Non-Ionizing Radiation Protection (ICNIRP).
