Sure, this Guardian article doesn’t frame it quite so vehemently, but I think after fifteen years, and the myriad studies done on the matter, the lack of appreciable increase in brain cancer rates should pretty much speak for itself.
In the review, “Health Effects from Radiofrequency Electromagnetic Fields” the advisory group considered hundreds of peer reviewed scientific studies that looked at the effects of mobile phone radiation on cells, animals and people.
“There are still limitations to the published research that preclude a definitive judgement, but the evidence overall has not demonstrated any adverse effects on human health from exposure to radiofrequency fields below internationally accepted guideline levels,” said Professor Anthony Swerdlow, chairman of the AGNIR and an epidemiologist at the Institute of Cancer Research.
Simon Mann of the HPA said that while the agency was not changing its long-held, precautionary stance that children should refrain from “excessive use” of mobile phones, “the reassurance that can be provided that there are no effects is much stronger than it was 10 years ago”.
In making recommendations for future research, the report emphasised a need to focus on new and emerging devices that emit radiofrequency radiation, and to gather more data on cancer risk among those who have used phones for more than 15 years.
So, because we can’t definitively disprove any ability of cell phone EMFs to cause brain tumors, despite the total lack of plausible mechanism by which these brain tumors might be caused, we leave the door wedged open that tiny crack so that nutters can keep talking about how dangerous it (potentially) is. And beyond that, the report actually suggests we move on to the next bugaboo, where (regardless of any actual indication that it might be dangerous) we should start studying something that has obviously been tested a considerable deal already. “Leave cell phones alone, start focusing on other EMF generators to see if they are deadly instead”, in other words. I am reminded of this XKCD comic.
The burden of proof has shifted, thanks to cranks and antiscience interests, to the point where one has to DISprove proffered claims like low-level EMF causing cancer, or the existence of extraterrestrial visitors who are really into anal, or that vaccines causing autism, or the existence of sperm-jacking women subjugating men in our society, or the planets’ positions at our birth affecting our destiny, or the existence of specific gods who want to trick us into believing we all evolved rather than being created ex nihilo, or the invisible hand of the market being the most self-evidently beneficial to the whole of mankind. This is the kind of bullshit we have to deal with as skeptics. That inversion of the burden of proof is probably the single biggest problem we face collectively as a species. It’s a bug in our kluge-heavy, evolved brains.
