The cancer rates in English nations speak for themselves. As does the rate of cancer for Americans located near farms or factories.
However, I don't see how low power radio-waves would be an issue under most normal usage, considering we are bombarded by them through space anyway.
So only "English" nations have high cancer rates? Seriously? Care to cite a study or do we have to take your word for it? I guess no one in Europe uses microwave ovens either.
