Natural uranium contains about 0.72% 235 U. Depleted uranium has lower mass fractions—up to three times less—of 235 U and 234 U than natural uranium. Since 238 U has a much longer half-life than the lighter isotopes, DU is about 40% less radioactive than natural uranium.
On 6 May 2014, the U.S. Army announced that it awarded a US$12 million contract to defense contractor General Dynamics for the demilitarization and disposal of 78,000 aging depleted-uranium (DU) tank rounds as newer rounds are added to the U.S. war reserves. The contract includes M829A1 and M829A2 rounds. [5] M829A3 Cross section
Aircraft and tank rounds sometimes use a core of depleted uranium. Depleted-uranium penetrators have the advantage of being pyrophoric and self-sharpening on impact, resulting in intense heat and energy focused on a minimal area of the target's armour. Some rounds also use explosive or incendiary tips to aid in the penetration of thicker armour.
When fired, depleted uranium becomes ‘essentially an exotic metal dart fired at extraordinarily high speed’
As a part of a $1 billion aid package, the United States announced this week that it is sending depleted anti-tank munitions to Ukraine to help Zelensky’s troops fend off Russian tanks. The ...

Similar neurotoxic effects occur in animals. [20] Particles of depleted uranium are 100 times smaller than leukocytes and easily bypass the blood-brain barrier, and are thus capable of reaching the olfactory nerves and disrupting cognitive processes directly. Antimony causes inflammation of cardiovascular, respiratory and digestive systems ...
