Resumo

Multiple simultaneous exposures to electromagnetic signals from various sources (multiple frequencies with high bandwidth) are a reality of daily life. In this study we investigated the non-thermal SAR (Specific Absorption Rate) for in vivo rats exposed to multiple electromagnetic (EM) field signals at 900 and 2450 MHz and 2 W power. The experimental system (ES) consisted of two vector signal generators, a directional coupler, a spectrum analyzer, a signal mixer, a power meter, and the GTEM chamber where the animal was located, immobilised in a rat holder. The 1g mean SAR values in eight different anatomical regions of the nervous system and whole body of the rat were estimated from experimental power measurements, with the aid of an FDTD software tool. After radiation, we use the enzyme-linked Inmunosorbent assay (ELISA) technique and we studied levels of HSP-90 and HSP70 in eight different tissues. Twenty-four hours after irradiation, the levels given protein HSP-90 and 70 in animals exposed to one or more frequencies showed significant differences respect control animals in the cerebral cortex and cerebellum. Multifrequency radiation causes changes in stress homeostasis of the nerve cells of the rat
