Here is several links on a very controversial subject on DU munitions and it's long term health effects not only with engaging with the enemy but it also expose's coalition troops to airborne DU matter which breathed in with have long lasting health effects and can cause sickness and death if exposed to great quantities of it in a short period of time. It's pretty lethal and it's half life is a 'mere' 4.5 "billion years". Despite it's penetration power against enemy bunkers and armour, it's way too dangerous to use, and it's cost to clean it up are very complex and very very expensive as well. I say ban the stuff asap!
