Background and Aim: Considering the great advances and extensive use of cell phones and its effects on the human communications and interactions, investigation of potential negative effects of cell phones on the users' health is necessary. The aim of this study was to determine the effect of the distance between cell phones and brain tissue on the temperature of the central and gray matters of the brain, because of the heat generated by radiofrequency waves.
Methods: This was an experimental study. Cow brain tissue was analyzed in a compartment with three depths of 2 mm, 12 mm and 22 mm, and at the distances of 4 mm and 4 cm from a cell phone, for 15 minutes. Lutron thermometer was used to measure the tissue temperature. Data analysis performed by using Lutron and MATLAB software packages.
Results: Temperature increase was more at the distance of 4 mm and in the depths of 2, 12, and 22 mm compared to that at the distance of 4 cm. Also temperature increase after removal of the confrontation was more than the baseline temperature at both distances which was higher at the distance of 4 mm.
Conclusion: Decreased distance between brain tissue and cell phone can increase the tissue temperature. Increasing the cell phone distance from the brain tissue can result in slower trend in temperature increase and decreased collective temperature after discontinuing the confrontation.
Key words: Mobile phone, Radiofrequency waves, Brain tissue, Temperature.
