# [ RadSafe ] WHO: Cell phone use and physics

Fri Jun 3 16:22:21 CDT 2011

```Because nobody seems to care computing E=h*f to know what are the energy
quanta emitted by the different household RF sources I do it for you
hoping that this nonsensical discussion comes to an end: The Plank
constant is 4.e-15[eV*s] (electron_volt*second) (e is scientific
notation of 10 to the power of ..)
quantum energy for
cordless phones maximum 3.e-6 [eV]
cell phone maximum 8.e-6 [eV]
WiFi maximum 4.e-5 [eV]

Such quanta don't even tickle biological molecules. What is the
temperature of such an energy? (Just because I have mentioned cooking),
once more
cordless phones maximum 3.e-6 [eV]  = 0.04 Kelvin
cell phone maximum 8.e-6 [eV] = 0.1 Kelvin
WiFi maximum 4.e-5 [eV] = 0.5 Kelvin

The background temperature of our universe = fossile temperature = 160
GHz = 2.7 Kelvin (it is freeeeeezing cold out there)

If you are not yet convinced of the cell phone cancer epidemiology
baloney, and you propose further research on it, well go ahead with
agnotology.

I stay with the laws of physics.
