There have been some attempts to reference actual facts in this thread, but the original hysterical post and the frequent misinterpretations of what this material is are leading to emotional outbursts.
We are no more likely to swallow uranium, depleted or otherwise, than we are likely to swallow bullets. We are discussing weapons here, and it is considered that weapons be extremely unsafe - to the opponent. If I'm in a tank and I know that depleted uranium armour is more likely to deflect anti-tank weapons than mere hardened steel, I'll take the uranium and worry about the after effects later.
Depleted Uranium means that the Uranium is less of a nuclear weapon than natural Uranium which has been mined for hundreds of years.
