Resumo

Exposure to non-ionizing electromagnetic radiation is increasing every day through mobile phones. In this experiment we try to find the influence of this exposure in twenty-four Sprague-Dawley rats brain when radiation is caused by a GTEM chamber (travelling wave chamber) and by a stationary wave chamber. Both chambers are irradiating at frequency of 900 MHz. The experimental system consisted of a vector signal generator, a directional coupler, a power meter and the two enclosures (working separately) where the animalwas immobilized by a methacrylate holder. In order to determine the radiation effects, rectal thermal measures are performed to calculate the SAR (Specific Absorption Ratio)values in the brain. We make a comparison between the radiation dosimetry in both chambers and we find that a GTEM chamber gives lower values for the average SAR than astationary wave chamber
