Equipments used by human are rapidly increasing and researchers try to pass the limits and save time. Users mostly are not aware of the disinfection of electromagnetism field and frequencies on the sensitive body cells and tissues as well as on their children, while these frequencies may cause disinfections on the body cells, some of which will reveal in short-term or long-term periods. Living tissues have different reflects on electromagnetism fields. Some tissues will strike severe disinfections in short-time and refuse acting normally, while other may dispose the filed longer, without any severe injury. The biologic effects caused by electromagnetism field depend on the their intensity, frequency, volatility, physical characteristics and the effected tissue. In lower frequencies, the electromagnetism waves, called non-ionizing waves, do not have enough energy for ionization. These waves indirectly generate free radicals. Due to long-life of free radicals, DNA damage increases. As a result cancer rises Generally, cell-phone antennas, telecommunication and high-voltage power towers cause magnetic fields and people exposed to it, influence negative effects of the waves.
