How and why do mobile phones and wireless devices cause harm?
Could you provide a link, since I would not be so sure.brewnog said:There have indeed been incidents where mobile phones have caused explosions at petrol filling stations, notably when the phone has been in the operators pocket and a call has come in.
Heh, most of my searches yield 'myth buster' sites. The problem is, all of these are busting the myth that the radio waves themselves can induce a current in metallic objects, which could potentially cause a spark. This has obviously been pretty thoroughly debunked. I think it was New Scientist (though possibly the Guardian ) which pointed out that some phones now use a high voltage display which is the cause of concern (this was around a year ago, I recall.). I'll try and dig out some links.Monique said:Could you provide a link, since I would not be so sure.

Well obviously zapping someone with X rays is pretty risky, and low frequency radio waves are accepted as being pretty safe. The truth is, mobile phones haven't been around long enough for any real studies to have run their course, so the answer is very much up in the air.mtanti said:So is there a frequency range in the frequency spectrum which is harmful (biologically!)?
We have the trees here too, some so real looking that eagles have nested in them. But whats a petrol station forecourt sign?petrol station forecourt signs.
