RF/microwaves biological effects and dielectric properties of human tissues.

Nowadays, the microwave and radiofrequencies are widely used (mobile phone, base station, wi-fi...) closed and near to the Human body (Children [1], pregnant [2], patients [3]...). The biological effects and health implications of exposure to radio frequency radiation have been widely investigated. Many factors affect the exposure of human body to radiofrequency radiations, this make the exposure assessment in a risk study very difficult to interpret. Ideally, the exact exposure dose should be measured, but there is no specified measure. In experimental situations, specific absorption rate (SAR), which is a measure of the maximum energy absorbed by a unit of mass of exposed tissue of a person, is used. Most of the research related to the RF and microwaves health effects neglects the most important parameter, which is the no uniformity of the biological tissues properties and theirs compositions. In this study, we will present the different models of the human body with its various Dielectric Properties of tissues, and see how it can affect the simulated and measured SAR values in human body.
