Cellular Canceration Induced by Mobile Phone Radiation

摘要

With the rapid development of communication technology, there is a widespread use of mobile telephone, whose effect on human has been getting more and more attention. The electromagnetic wave can penetrate biosystems and interacts with biological tissue at different biological levels. Although many researchers have been studying biological effects of electromagnetic radiation for years, their results are not consistent and need to be confirmed by reliable and repeatable experiments. Since the energy of electromagnetic radiation of mobile phone is much low and the organism has an adaptability to external stimulation, short-time radiation may not induce obvious effect on organism. To avoid other inductive factors in the environment, we used in vitro cell culture technology and exposure experiment to study the activating effect of 900 MHz electromagnetic fields (EMF) on NIH/3T3 cells. NIH/3T3 cells are sensitive to sarcoma virus focus formation and leukaemia virus propagation, and therefore are often used for DNA transformation studies. The NIH/3T3 cells were divided into four groups, the control group with sham exposure and the three exposure groups exposed to 10W/m2, 50W/m2 and 90W/m2 916MHz EMF respectively. The exposure lasted 2 hours a day. After exposure we found the cells morphology changed and had the characteristics of epithelial cells. The Soft agar assay showed that all the exposure groups formed colonies in soft agar while the control group did not form colonies. The results in this study suggest that 916MHz electromagnetic waves can promote malignant transformation of NIH/3T3 cells and induce cellular canceration .
