The effect of cell phone radiation on blood and cancer Risk

Abstract

<strong>Introduction</strong>: The continuous rapid growth of the telecommunications industry and common application of cell phones have raised debates on the human health risks associated with exposure to radio frequency fields due to these phones or their base stations and other sources such as radar, radio/television waves, and industrial and medical applications. This study aimed to investigate the effects of cell phone radiation on blood factors and Cancer Risk. <strong>Materials and Methods:</strong> In this study, 48 mice were divided into 6 groups of 8 (one control, and 5 exposure groups). The 4 exposure groups, twice daily were exposed to radiation waves for 30 minutes, one, two, and 4 hours and the fifth exposure group is 4 hours' single fraction radiation once day at 900 and 1800 MHz at 2 watts' power, over a period of one month. Then blood samples were taken from the heart and blood factors were analyzed and The hippocampal expression of P21and P53 mRNAs were evaluated using Real-Time PCR. <strong>Results:</strong> Of the 10 blood factors, only mean concentration of cell hemoglobin (MCHC) in the 0.5 hours' exposure group, and mean value of the mean cell hemoglobin (MCH) in 0.5, 2, and 4 hours' exposure groups, showed a significant difference with those of the control group (P<0.05). The ratio expression of P53 and P21 genes was increased to greater than one (P53/P21>1) in all experimental groups compared to controls, except for the group with 2 hours twice a day exposure. However, there was not significant differences between the expression level of P53 and P21 genes among the experimental groups using paired t test (p>0.05). <strong>Conclusion:</strong> Since human's whole body is exposed to electromagnetic radiation from mobile phones and antennas, some blood factors could be, to a small extent, affected by adverse effects of mobile phone electromagnetic waves. In fact, radio frequencies of mobile phones damage brain cells depending on the duration of the conversation (the duration of radiation).
