"NORM" --
http://www.world-nuclear.org/info/inf30.html">Naturally-Occurring Radioactive Material -- is quite common, and burning coal for energy concentrates it. (The paper I linked to draws from scientific, not opinion, sources.)
We also get nearly all our

(this paper may be embargoed from the public) from geological strata that concentrate uranium and thorium at high levels. These phosphates can be mined for nuclear fuel, too, and have been. Instead, we put this stuff on our crops -- even the organic ones.
Yet nobody in the anti-nuclear movement seems all that concerned about these sources of nuclear material. Greenpeace, for example, wants a 10-year phase-out of the nuclear industry, but is content to allow 40 years for a coal phase-out. I have yet to see any evidence that Greenpeace is even aware of NORM radionuclide contamination in agriculture.
None of these issues are the simple us-vs-them disputes a lot of DU E/E participants seem to think they are. We literally need a top-to-bottom review and revision of the way we conduct our entire civilization. A smaller population under less pressure and inflicting less damage could afford to overlook problems in the interest of political and financial expediency. We can not.
If this was all that clear-cut and simple, it wouldn't be a problem now, would it?
