QUESTIONS AND ANSWERS

Q. Why is the information only now being declassified?

A. Information on using depleted uranium parts in weapons was classified to protect certain weapon design information. The Rocky Flats Plant no longer produces weapons parts. Thus, it is now possible to declassify some information on the inventory and processing of depleted uranium at the Rocky Flats Plant.

Q. Does the depleted uranium at the Rocky Flats Plant represent a hazard to the public?

A. Depleted uranium, which by definition contains less uranium-235 than found in naturally occurring uranium, presents very little hazard to the general public. This material, which is stored in large quantities at the Rocky Flats Plant, has much lower radiological and about the same toxicological hazard concerns as highly enriched uranium. Engineering and administrative controls are in place to preclude normal or accidental release of this material that could potentially impact the public. These controls are also in place to ensure the protection of occupational workers at the Rocky Flats Plant. Overall, controls are in place to ensure that the public is not exposed to this material and that it does not present a significant risk.
