Well, I only considered the energy in the range of 1 cm. A cell phone
puts out about 100 mW peak of which you get about half with it hung in
your ear. In ten seconds, you get about half a joule of radiation.
But it's not ionizing radiation, which is why it probably doesn't
matter. Hold your conversation while sitting outdoors in the sunshine,
and you get a really whopping big dose of additional radiation -- and
some of that stuff from the Sun is UV, which *is* ionizing radiation,
and it probably does a lot more damage to you during your conversation
than your phone does.
The normal mode for using a cell phone is to hold it tight against your
head. Your head, frankly, doesn't contain much that's terribly
sensitive -- your brain cells hardly ever divide (neurons, never, other
brain cells maybe once in a while), and nothing in your head ever
undergoes meiosis. There's no ionizing radiation coming out of the
phone, so what's it going to do to your head? Scramble your thoughts?
That should be obvious right away, and it's not, so it's presumably not
happening.
If you used a cell phone by, say, sitting on it, or holding it tight
against your abdomen, the story might be different, and the consequences
a lot more dire. But you don't.
BTW I seem to recall there are some subtle effects from microwave
radiation on chemical reactions (I mean, aside from the effects of
heating) which were detected some time in the last few years, but
they're subtle, and don't seem likely to cause a lot of trouble for
such a relatively inactive bunch of cells as those constituting a brain.
The CBE at 1 cm is on the order of an erg which is 10^-7 joule. I
didn't bother to calculate the steradians occupied by your head.
So yes, there are many variables. Have your read _Cell_ by Stephen
King? Helluva an experiment we are performing on ourselves.

Show this in better detail. it depends a lot on how close the mobile is.
Another factor is that we have like 100% exposure to cosmic radiation but
only 2% to mobile phones.
If it is as bad as you say then we are smoked, or rather irradiated.
Specifically the gender cell productions is challenged and during the last
decades the sperm quality has declined dramatically. Radiation is likely
used in meiotic recombination, a process in production of sperm cells and
ova.

The CBE is about 5 to 6 orders of magnitude less than cell phone
radiation. Also, cell phone radiation peaks near the microwave oven
frequency. Doh!

Hi
In determining the hazard of mobile phones I came to think of one way of
doing it. Compare the net effect from
http://en.wikipedia.org/wiki/Cosmic_background_radiation and other
natural
sources and compare that with phones. If phoneas are equal and less then
there wouldn't be much of a problem.
