I would be interested to know how cellphones expose one to radiation. I was thinking these were microwave, which is a much longer and less powerful wavelength than gamma radiation.
Ever heard of a microwave oven?...There is a reason they use microwaves of a certain frequency because water absorbs the radiation and this heats it up.
The human body is mostly water but it also has DNA to worry about and one of the side effects of heating water in the human body is DNA damage...And that can lead to Cancer...This is why the extended use of mobile phones, which TX at microwave frequencies, is becoming a cause of concern to many. Ever wondered why your head feels warm when you have been talking on your mobile phone for a while...Well now you know!
