Depleted uranium (DU), also referred to in the past as Q-metal, depletalloy, or D-38, is uranium with a lower content of the fissile isotope 235 U than natural uranium. [2] The less radioactive and non-fissile 238 U is the main component of depleted uranium.

2024年12月3日 · depleted uranium, dense mildly radioactive metal that is primarily used in the production of ammunition and armour plating. Depleted uranium is created as a waste product when the radioactive isotope uranium-235 is extracted from natural uranium ore.

2024年10月10日 · U-235 makes up a very small portion of uranium ore. It must be extracted through an enrichment process that leaves the remainder of the ore behind. This remainder is known as depleted uranium....

2023年9月7日 · Depleted uranium is naturally-occurring uranium which has been stripped of much - but not all - of its radioactive matter. It is a by-product from the process which prepares uranium for use...

2025年1月13日 · First deployed on a large scale during the Gulf War, the U.S. military uses depleted uranium (DU) for tank armor and projectiles due to its high density, helping it to penetrate enemy armored vehicles.

2025年1月13日 · Depleted uranium (DU) is the material left after most of the highly radioactive form of uranium (U-235) is removed from the natural uranium ore. DU has several common uses. Naturally occurring uranium ore is abundant in nature …

What is Depleted Uranium (DU)? In order to produce fuel for certain types of nuclear reactors and nuclear weapons, uranium has to be "enriched" in the U-235 isotope, which is responsible for nuclear fission.

2023年9月7日 · Depleted uranium is a dense by-product left over when uranium is enriched for use in nuclear reactors or nuclear weapons.

Depleted uranium typically contains about 99.8% 238U, 0.2% 235U and 0.0006% 234U by mass. For the same mass, depleted uranium has about 60% of the radioactivity of uranium. Depleted uranium may also result from the reprocessing of spent nuclear reactor fuel.

2020年1月22日 · Depleted Uranium. Since the first Gulf War, and continuing through to modern military operations in Iraq and Afghanistan, the use of depleted uranium (DU) has caused concern among veterans. In this fact sheet, we will help explain the significance and validity of these concerns. What Is Uranium? Uranium (U) is a dense, weakly radioactive *
