Abstract

Electromagnetic fields (EMF) have been used in medical equipment called Electrical Impedance Tomography. The most important problem is to ensure the safety for the living organisms exposed to EMF, creating the principles of dosimetry. The condition of quasi- stationary is fulfilled, thus the two components: electric field (EF) and magnetic field (MF) may be analyzed separately. This paper presents the energetic model of interaction between human organism and EMF and relations between MF induction and EF intensity. In order to determine the value of MF induction corresponding to EF intensity the total thermal energy absorbed in human organism in EF has been compared with the energy absorbed in organism in MF. As the result the diagrams of MF induction corresponding to the EF int
