Human EMF Exposure Health Hazard Range Modeling

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 regulations 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. It´s 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 modeling based on the worst case principle in UHF wireless system. It´s impropriate to evaluate compliance boundary in MF wireless system. Near field problems which occur in these frequencies must be solved in case by case manner. Appropriate terrain modeling is crucial for correct calculations of field strength and prevention of harmful exposures.
