However, with its popularization, increasing attention has been paid to its influence on humans. In addition, another study showed that significant psychiatric symptoms were observed in people who worked in these areas. J Neuro. However, other reports have indicated that unlike ionizing radiation, the microwave radiation produced by mobile phones does not possess sufficient energy to directly damage DNA.
