OK , so the 2.45 GHz frequncy spec. spike increases the rotational
energy which has the rather dramatic effect of heating the water.
I thought that vibrational resonance would heat water.
I never read up on it though and while I know a bit about DSP and RF
I can't claim to now much about the physics of water molecules.
Are there not other risks , besides the obvious heating effects of
radiation within a relatively tight band of 2.45 GHz ??
I suppose that the jury is still out on this. Worrying all the same
considering the proliferation of mobile phones in use at the mo.
I was reading that studies had been carried out on the most popular
see which ones emmited the least amount of radiation . That is as
specific as the report got. Totally ignored colour of radiation .
Anway they found that the motorola phones , star tac in particular were
'safest' by a long way. Why are they radiate less , absorb more. Do
know someething that the other manufacturers are ignoring ?
Just my >.02 euros worth..
