System for animal EM exposure with well defined dosimetry

The whole-body exposure system for unrestrained mice was designed in order to analyze the influence of electromagnetic field. The setup operating at 900MHz was designed with respect to induced uniform field, external radiation elimination, absorbed power determination, sufficient space for mice movement together with even mice exposure and costs. The main aim of this paper is to assure that the dosimetry results reached by computer simulations can be used for determination of absorbed power in the unrestrained mouse. The whole-body exposure chamber with anatomical mouse model was simulated by two different numerical methods: finite-difference-time-domain method (FDTD) and Finite Integration Technique (FIT) and its dosimetry results were compared by computed SAR values. In our contribution we will describe our first results dealing with observed biological effects of EM field, obtained by real exposures of experimental animals.
