- Abstract
- The electromagnetic radiation emitted by mobile phones and base antennas can penetrate tissues of the human head, and can be absorbed and transformed into heat. Due to the increase of mobile telephony, there is interest in studying its effects on human health. An analysis of the medical literature from 1996 to 2013 was carried out through internet searches using Med-line and PubMed. Using mathematical modeling, the effect of 0.9GHz frequency was studied. The finite difference model was used to predict specific absorption ratios in W·m-2. The finite element model was based on a horizontal section of a 10 years old child head at eye level. Two dimensional analysis and a minimum thickness were used. The finite difference model predicted specific absorption ratios reaching 0.72W·m-2, while 2.0 is admitted by the European Union. Calculations of absorp-tion obtained from finite element predictions (to determine the displacement of the electric field) showed a better match for the 2009 version (0.685W·m-2). The new 2014 version peaked at 0.636W·m-2, but has slight differences between the 2nd and 3rd subdivision of the cerebral hemisphere. However, this la-test version of the finite element software has a good agreement with the results obtained by other authors. Modern software tools allow modelling the effect of cell phones on the brain but there are some minor differences between the predictions of di-fferent computer programs.
