AM Radio Waves May Be Harmful?
Klar writes "Wired News reports that: 'Korean scientists have found that regions near AM radio-broadcasting towers had 70 percent more leukemia deaths than those without.' The article continues: 'The study, to be published in an upcoming issue of the International Archives of Occupational and Environmental Health, also found that cancer deaths were 29 percent higher near such transmitters.' While 'their study did not prove a direct link between cancer and the transmitters', the FDA and the World Health Organization are urging more studies, especially of radio waves from cell phones."
When you have statistics as your only data and no matched control group, most of the correlations you can find will be coincidence or garbage.
Epidemiologists use the heuristic that they start paying attention when one group has three or more times the risk of another group.

Smoking is a good example: the risk of lung cancer among smokers is about thirty times higher than among nonsmokers.
>Find me a control group. You can't, not on this planet.
That's what lab studies are for. You can shield one group of rats from RF and microwave a genetically identical group. You can start from conception and have useful results in a year.
>Why are you all so reluctant to even entertain the notion that non-ionizing radiation might create a health risk?
After a hundred years of experience and a zillion negative lab studies skepticism is indicated. I'm willing to be surprised but I don't expect to be.
