Avaliação dos efeitos comportamentais da radiação eletromagnética: uso do modelo animal experimental.

Abstract

Every day we are subjected to a large amount of electromagnetic radiation, in particular in the waveband. This track is emitted by devices disseminated in our society, like cell phones, televisions, radios, radars, use of wireless internet and the presence of base stations (responsible for the operation of the cell). Several studies pointed to the possibility of deleterious effects resulting from this exposure on human and animal health, including the likely injury from cognitive and behavioral changes. Due to the limited data in the literature of behavioral effects, seek through experimental model to verify this possibility. The aim of this study was to investigate the possible behavioral effects of electromagnetic radiation (EMR), at the levels of radio frequency (RF) of 850MHz in rats. The study included a group of six rats, Rattus norvegicus, male, albino, with weighing between 250 and 300g, were exposed to REM frequency of 850MHz, 2 hours per day for 10 days and were subjected to behavioral tests (open field test, elevated plus maze, forced swim test and Morris’s maze) before and after irradiation. The data produced in this test were analyzed by analysis of variance (ANOVA). The results showed an increase in the number of pats during the behavioral tests, after the radiation and a larger number of entries into the closed arms of the elevated plus maze test. These changes may be linked to an increased activation of the autonomic nervous system and anxiogenesis, generating a defensive behavior. There were no deficits in learning and memory in mice after exposure to REM.
