http://www.acma.gov.au/~/media/Technica ... phones.pdfso maximum transmitter power for a mobile phone is around 125mW, which is very low. most of the time it would be operating far below that too, because it turns down the transmitter to a level to the lowest possible level to maintain reception (to increase battery life)
I have done an RF safety course, and usually RF radiation starts to become an issue at 10W or higher.
something like a hand held marine radio can transmit 7W or so, and there are recommendations to hold them 10cm or more away from your head etc.
One of the issues that others have focussed on is the contention that the field is being concentrated by the antenna, and another the argument that the field intensity goes up when the phone is not at idle but actively trying to maintain a signal particularly in difficult areas. A third is the argument about whether the declared safety limits are really safe. The Neurosurgeon, Vini Khurana, doesn't argue from physics and theory but from clinical data in his practice.
But the Physics and Maths of this is not my forte, so I'll take the cautious line rather than accept the reassurances...
(Note my comment above about authorities ignoring the link between cancer and diesel fumes despite the W.H.O. published statement - the risk gets played down if it is going to cost too much to fix.)
