Dosimetric analysis of an in vivo exposure setup at 3 GHz

International audienceIn last decades, the widespread and daily use of radiofrequency systems has made necessary risk assessment on human health. For this reason, biologists and physicists are working together to study the interactions between microwaves and living matter. Many exposure setups have been used for mobile phone but also for radar applications. Some radars used in the French Navy are characterised by high peak power and ultra-short pulses emissions. Restriction limits have been established by calculation. It is necessary to improve the knowledge on biological effects of such exposures in order to validate the current security zoning on vessels, and also to face possible contentious situations. We have developed an in vivo exposure setup in order to simulate human exposure to high power electromagnetic pulses emitted by specific radars at 3 GHz (S band) on animal model (rats). The aim of this work was to perform numerical and experimental dosimetry of this exposure setup. The setup, located in anechoic chambers, is composed of a coaxial antenna to illuminate six rats freely moving in six plexiglas boxes. A detailed description of the setup will be shown in the poster
