oK, what is the ‘dust’ hazard?
cleaning up a tank battle?
cleaning up something shot up by an A-10?
other?
Both
Btw, DU is less than half as radioactive as natural uranium, which, in turn, is quite safe to handle (though not to inhale).
Those were depleted uranium rounds. Heavy metals whether radioactive or not, are toxic, and when a high velocity round like the 30mm the A10 fires or the sabot round a tank fires hits a hard target, some of the round will heat up, vaporize burn etc so you have this heavy metal dust that makes it much easier for the body to ingest.
It would be similar if they used tungsten instead of uranium.
