The west has know about the dangers of Depleted uranium since the Gulf Conflict, and before. Yet no one in Government will admitted it.
WHAT IS DU?
Depleted uranium is actually uranium 238. U-238 is the non-fissionable residue of the uranium enrichment process. Some confusion seems to exist in the U.S. Department of Defence and the U.K. Ministry of Defence officials try to confuse individuals by claiming that internalized DU contamination is natural uranium rather than DU.
