Abstract


The biological and health effects of electromagnetic fields are a current concern. With the aim of evaluating these effects, it is essential to estimate the levels of human exposure to various types of electromagnetic sources within different environments. These assessments could be performed by determining the current density distributions inside organs or tissues, by modeling the different mechanisms of electromagnetic exposure or even by modelling the development of effects in living beings. Everything should be done while considering various exposure scenarios. In this paper, we have determined, through simulations employing CST Suite Studio software, the specific absorption rates (SARs) values for a human body, averaged from the values for different 10 grams of tissue in different areas of the body, in the case of its exposure to an electromagnetic field generated by a source placed in the far field domain, where the human body is located in an empty room inside a building. We have used our previously tested 3D human body model that has the geometry of an elliptical cylinder. The simulated SAR values have been also compared with the reference levels accepted by the International Commission on Non-Ionizing Radiation Protection and IEEE Standards for Safety Levels for both public and professional exposure.
