Wow. Good link, AF, the voice of reason. What it doesn't add is the small background dose from nuclear weapons tests in the 60s, but that was a time when the truth was concealed. And in relative terms pretty small http://en.wikipedia.org/wiki/Background_radiation and I'd forgotten how much radiation some coal fired power stations produced.

The article could have also explained better the large variation in natural doses. Interestingly many American's were zapping themselves in the past due to build up of natural radon in their poorly ventilated basements (that no doubt sometimes doubled up, ironically, as nuclear shelters).

But what flabergasts me is this is the first time I've seen something from the 'States that does not use some ancient and totally out of kilter units of measurement (Curies, Rems, Rads).
