EMF myths FAQ

Is the power output of a mobile phone enough to make the brain boil?

No. The maximum power output of mobile phones is 2 watts and, in most cases, much less than that (an average of 0.25 watts).The thermal effect of electromagnetic waves may cause a slight warming of the body, comparable to the warming that results from physical exercise or exposure to the sun's rays. But it cannot make the brain boil.

Note that the heat produced by a mobile phone is not only caused by wireless transmission. Some types of device produce a very slight amount of heat due to battery warming, when used for a long period of time.
