XopherMV writes "A study by Lai and Singh, published in a 1995 issue of Bioelectromagnetics, found an increase in damaged DNA in the brain cells of rats after a single two-hour exposure to microwave radiation at levels considered "safe" by government standards. The idea behind that study was relatively simple: expose rats to microwave radiation similar to that emitted by cell phones, then examine their brain cells to see if any DNA damage resulted.
The news was apparently unwelcome in some quarters.
According to internal documents that later came to light, Motorola started working behind the scenes to minimize any damage Lai's research might cause even before the study was released. In a memo and a draft position paper dated Dec. 13, 1994, officials talked about how they had "war-gamed the Lai-Singh issue" and were in the process of lining up experts who would be willing to point out weaknesses in Lai's study and reassure the public.
To this day, the cell phone industry continues to dispute Lai and Singh's findings although half of about 200 studies say there is a biological effect from cell phone radiation.

Testing Cell Phone Radiation on Humans 159 comments
Palm Addict writes "News.com reports that Finland's radiation watchdog is to study the effects of mobile phones on human proteins by direct tests on people's skin. From the article: 'A pilot study, to be conducted next week, will expose a small area of skin on volunteers' arms to cell phone radiation for the duration of a long phone call, or for one hour, research professor Dariusz Leszczynski said on Friday.'"

P.S. I see this study was done at my alma-matter, the University of Washington. I wonder if my old roommate Jim Oliver might have been affected, since he did handstands from our 7th floor balcony railing [komar.org] - maybe he should have been wearing a tin-foil hat? ;-)

Answer: because cell phone radiation doesn't cause cancer at any rate appreciable from statistical noise, IF AT ALL.
Do you realize the gasolene vapor and diesel fumes are far more likely to give you cancer, that they're both known, proven, undisputed carcinogens?

SAR Testing (Score:5, Informative)
This site [sarshield.com] has a list of SAR ratings. For a phone to pass FCC certification, the phone's maximum SAR level must be less than 1.6W/kg (watts per kilogram). The SAR levels shown in the linked chart represent the maximum SAR level with the phone next to the ear.

Althoguh from what I understand the new digital cells are nothing like analog phones for the amount of energy they put out. I know when I'm in an analog only area my phone goes flat in less than a day, compared to 3-4 days when I have digital service. So anecdotally I'm seeing maybe 1/3 to 1/4 of the power output with digital.

So you really have to resort to some fancy hypotheses to rationalize this. Well maybe, just maybe, there is some kind of a resonance of the current through an ion channel (although I'm not entirely sure that this is even plausible), which somehow alters its coupling to some intracellular kinase or other second messenger system, which activates an enzyme that happens to produce free radicals, and those break DNA. But I'd have to see some definitive evidence before I take that kind of hypothesis seriously.
The point is that "microwaves damage DNA" is an extraordinary claim that requires extraordinary evidence. "Some studies support it and some do not" simply doesn't qualify.
I'm skeptical of "DNA break" assays, anyway. There is a long history of people finding DNA damage by this and that, and others failing to reproduce the result. It's easy to break DNA--you can even break it by rough handling.

I know it sounds weird, but when I was at University of Missouri-Rolla, I did some work at the nuclear reactor on campus. There is far less radiation inside the reactor building (not inside the reactor core itself) than there is outside on the hockey puck (a big concrete circle in the middle of campus). So, if you are worried about radiation, just move into a nuclear reactor building.

The next step would be to test on higher-evolved species and mammals (e.g. guinea pigs, cats, eventually primates) to iron out the concerns you've identified. Most likely by the time it reaches humans this will not be a relevant matter... but at least there is some preliminary evidence that would suggest further testing is required.

From TFA:
Lai says there have been about 200 studies on the biological effects of cell-phone-related radiation. If you put all the ones that say there is a biological effect on one side and those that say there is no effect on the other, you'd have two piles roughly equal in size. The research splits about 50-50.
"That, in and of itself, is alarming," Lai says. But it's not the whole story. If you divide up the same 200 studies by who sponsored the research, the numbers change.
"When you look at the non-industry sponsored research, it's about three to one--three out of every four papers shows an effect," Lai says. "Then, if you look at the industry-funded research, it's almost opposite--only one out of every four papers shows an effect."
