A photon emitted from a mobile phone antenna has about five orders of magnitude less energy than a photon of visible light. It just isn't plausible that such a relatively small number of relatively low-energy photons could have a meaningful impact on human heath, considering our overall exposure to electromagnetic radiation.

Sure. 3 Watts of gamma rays will do a different job. But a cell phone works in the microwave range - visible light, infrared, UV are all more dangerous - and the sun will blast you with 1 kW on a nice sunny day.

Cell phones are not the problem (well, not the microwaves at least).

E = hf

You can measure the energy of one photo using this equation.

Microwaves at 2.45 Ghz = 1.6243499999999998e-24 eV

Gamma radiation at 3 x 10(19) Hz = 1.9889999999999998e-14 eV

So about 10(10) more energy per gamma ray photo or about 10 billion times more energy.
