ANY level of radiation above ambient will cause some effect on it's surroundings, otherwise no data could be transmitted using it as a signal. 3 watts is definitly above ambient. I'm not saying it's a health hazzard as I know very few people that have large lumps hanging out of their ears or anything like that, and I know a lot of people that use cell phone's extensivly. Including myself for several years, but I don't currently use one on a regular basis. But it's simple contact with additional stimulous not ordinarily encountered that people can't argue with. Exactly what those effects are aren't known. Some have even argued (I can't quote the study this was over a year ago) that people exposed to the higher levels of radiation found within a short distance of cell towers (note tower's not phones) actually had an increased level of mental activity (wasn't precisly defined) The whole thing was probably tripe, which is likey what the current round of medical tests that currently exists about cell phones and exposure to their radiation for either extended or brief periods of time. It takes YEARS (20-30 or more) to run these studies with any degree of accuracy. The effects of these wavelengths and power levels on brain tissue, or even brain neural pathways is a complete unknown, the human body is a great antenna and absorbs and admits RF radiation at a very wide band of frequencyes (who hasn't been near an AM/FM radio that would stay in tune only if a person was near the antenna)
Several very simple points that sum it all up completly unbiased.
NOTHING definativly says increased exposure of cell phone radiation is hazzardous to your health.
NOTHING definativly says increased exposure of cell phone radiation is beneficial to your health.
Prudence dictates if you can't quantativly value the positive or negative benefits of a thing then exposure to it or the state in which it might have it's most effect on you should be limited as much as possible by common sense, until such things are known.
By the way, Artem, most of the people on the planet ARE idiots. Not to say they're stupid or dumwitted, but more to say people are easily fooled by the words 'study' and fearmongering is insanely popular nowdays. I think my favorite example of a very simple proof of this would be on the television show on Showtime called "Bullshit" In which they have a 'protestor' at an environmentalist rally asking people to sign a petition to ban Dy-hydrogen monoxide (water) and a LOT of people signed it, out of some percieved notion of it acomplishing good.
So really the whole entirety of this thread is nothing but pure mental floss untill long term factual studies from reputable institutions come up with numbers that can be directly related to these claims in direct double blind clinical tests of real world usage.
