Although the cell phone industry continues to claim that their products are safe, there is still no scientific data available to prove this. Evidence to the contrary, however, is mounting every day.
In essence, your cell phone is a radio. When you talk on your cell phone, your voice is transmitted from the antenna as radio frequency radiation (RFR) between 800 MHz and 1,990 MHz. This frequency falls in the range of microwave radiation and, when you are exposed to it, there may be a chance of health consequences.
Depending on how close the cell phone antenna is to your head, between 20% and 60% of the radiation emitted by your cell phone is transferred into your head. The radiation actually penetrates the area around your head and is absorbed, with some radiation reaching an inch, to an inch and a half, into your brain.
Cell phones are designed to transmit radio waves in all directions because base stations can be located in any direction with respect to phone users. This means that portions of the radio waves they produce are directed towards your body. The diagram of the person and the radio tower illustrates how this can occur
