2 of the 17,000 + pages from the Nuclear Regulatory Commission.

The below pages show some of the extent of the knowledge of the hazard associated with depleted uranium and DU dust dating to 1966.

Note what the information says about being upwind from the hazard, then note what the medical effects are of being contaminated with DU. It would appear the medical effects are "medically significant", something well-known to the NRC, Aberdeen and the Department of Defense as early as 1966, 25 years prior to its first use in combat during the Gulf War.

On the second page, please read what was rquired in 1966 to avoid contamination from DU dust when test-firing DU munitions then ask yourself why it has taken the DOD over 30 years to train soldiers who would use the munition in combat how to avoid the same hazard.
