this is a factual comment. most of DU's toxicity is chemical in nature. that doesn't make the pictures of deformed babes any easier to behold, tho. also, alpha emitters are basically harmless until they're ingested/inhaled.
Yes, I hope my comment is not taken as defending DU as being OK. I was specifically replying to the idea of this becoming some kind of new Chernobyl exclusion zone.
