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 animal was 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 performed a comparison between the radiation dosimetry, compared the stress levels of the animals and finally we studied the neuronal activation with immunohistochemistry test c-fos in the brain of animals exposed to radiation in both chambers. We found that a GTEM chamber gives lower values for the average SAR than a stationary wave chamber. Stress levels in animals are higher in the cavity standing wave than in the GTEM. Postmortem neuronal activation in the brain appears with a different pattern: unilateral in traveling wave and bilateral in standing-wavespa© XXVIII Simposium Nacional de la Unión Científica Internacional de Radio.
