depleted uranium

The metal remaining after the most active radioisotope (²³⁵U) has been extracted from uranium. It is a heavy metal, used in munitions, e.g., in armor-piercing weapons.

It is estimated that, worldwide, more than 1 million tons of depleted uranium are stored. About 95% of the depleted uranium produced until now is stored as uranium hexafluoride, (D)UF₆. The long-term storage of (D)UF₆ presents environmental, health, and safety risks because of its chemical instability. When UF₆ is exposed to moist air, it reacts with the water in the air to produce UO₂F₂ (uranyl fluoride) and HF (hydrogen fluoride), which are both highly soluble and toxic.
