US reluctance to talk about DU
Scott Peterson 1999
International attempts to assess the risks from depleted uranium (DU) bullets used in Kosovo and Serbia are being thwarted by American reluctance to pinpoint where DU was used.

As part of a sweeping United Nations environment damage assessment of the Kosovo conflict, UN agencies have made inquiries about exactly where and how much DU ammunition was used in the 78-day NATO bombing campaign. So far, they have received little data.

Remains of toxic bullets

Fresh-from-the-factory DU tank shells are normally handled with gloves, to minimize the health risk, and shielded with a thin coating. The alpha particle radiation emitted by DU travels less than an inch and can be stopped by cloth or even tissue paper. But when the DUmaterial burns (usually on impact; or as a dust, it can spontaneously ignite) protective shields disappear, and dangerous radioactive oxides are created that can be inhaled or ingested.
