Depleted uranium is mildly radioactive, but poses a considerable health threat as a heavy metal poison or toxin.
Depleted uranium is uranium with a content of the isotope uranium-235 under 0.7 %. Natural uranium has been processed to change (increase) the concentrations of lighter isotopes, and the "leftovers" are termed depleted uranium. Let's look at this heavy metal and sort things out. Without splitting hairs, the element uranium as it comes out of the ground is almost 99.27% U-238, and about 0.73% U-235. There's also a trace of U-234 in it. The isotope U-235 is the desired one for use in nuclear fuels and in nuclear weapons. Uranium is processed or "enriched" to increase the amount of the lighter isotope in the the finished product. This leaves the rest of the uranium "depleted" of some (or much) of its U-235 (and U-234, for what it's worth). The term depleted uranium is then applied to the remaining uranium. A link can be found below to check facts and gather more information.
Any gene; depleted uranium is uranium containing more than 99,8 % of the isotope uranium 238.
The primary health threat of depleted uranium (DU) is its potential toxic effects when absorbed into the body. DU can cause kidney damage, lung cancer, and harm to the reproductive system. It is considered hazardous mainly due to its radioactivity and chemical toxicity.
The external irradiation from depleted uranium is not significative.
Depleted uranium is man made but the isotope 238U is natural.
Depleted Uranium Is a War Crime was created in 2006.
Depleted uranium is approx. 60% less radioactive than an equivalent mass of natural uranium.
You'll have to make your question more clear. Are you talking about depleted uranium munitions? Or are you claiming the US are using depleted uranium for something else?
