The gaining importance of mobile phones is raising a concern on the electromagnetic (EM) radiation effects on human health. Mobile phones are generally placed near head during communication and the radiation emitted interacts with the biological tissues and changes the electrical properties. Brain which generates electrical signals is taken as the point of analysis in this study. Due to inherent difficulties in involving human for such experiments, an electrically similar phantom is developed to determine the EM field interaction with the biological tissues from 800 MHz to 2.4 GHz using a Vector Network Analyser (VNA). The obtained dielectric values are compared with the literature values to verify the correctness of the phantom and accuracy of the experimental set-up. Then the electrical changes are correlated to the biological changes based on the changes taking place in ion concentration in the brain tissues when exposed to various frequencies. The statistical evaluation of this study indicates that the impact of EM radiation is comparatively higher on cerebellum and white matter. |
