Human health safety limits compliance boundary modelling for typical UHF communication systems

Former research brought standards that define electromagnetic field strength safety limits regarding human health in order to prevent harmful exposures. All wireless devices must comply those regulatives so there is a need for electromagnetic exposure inspection. In broader analysis it is reasonable to apply more complex, but consistent procedure for harmful area valuation by determining the compliance boundary. Itpsilas very difficult to model compliance boundary accurately and even if it would be possible it would be of no use. The paper presents simple compliance boundary modelling based on the worst case principle.
