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.

What is Sucre en poudre?
Sucre en poudre is the French term for powdered sugar or confectioner's sugar. It is a finely ground sugar with a small amount of cornstarch added to prevent clumping. It is commonly used in baking and dessert recipes.
The VSEPR formula for a molecule of type AB2E2 tells you that the molecule is made up of what?
The molecule is made up of one central atom (A) bonded to two identical atoms (B) and two lone pair electrons (E). This arrangement results in a tetrahedral shape where the lone pairs are placed in opposite positions to minimize repulsion.
What is blister packaging made from?
Blister packaging is typically made from materials like PVC (polyvinyl chloride), PET (polyethylene terephthalate), or other types of plastic. The plastic is molded into the desired shape to create the cavity that holds the product, and then sealed with a backing material like foil or paperboard.
What is the Uranium-235 content of depleted uranium du?
Typically under 0.3%
The depleted uranium DU load in a patient is measured by the uranium level in what?
The uranium is determined in urine or blood.
The Depleted Uranium (DU) load in a patient is measured by the uranium level in what?
The uranium is determined in urine or blood.
The primary health threat of depleted uranium or DU is from its toxicity as what?
Depleted uranium is mildly radioactive, but poses a considerable health threat as a heavy metal poison or toxin.
What is correct about Depleted Uranium DU?
clothing and skin will block the majority of the alpha and beta particles.
The primary health threat of depleted uranium DU is from its toxicity as a?
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.
What illness did the soldiers have after the desert storm war?
A new and different category surfaced from this operation; Depleted Uranium. Some projectiles used this material as it was one of the hardest known elements that could penetrate obstacles. When it did so, DU (Depleted Uranium) dust particles became present...when personnel made contact with it, inhaled it, etc. They possibly became ill, or suffered some other unknown negative effect(s).
Does radiation emitted from DU materials pose the greatest contamination danger?
While radiation emitted from depleted uranium (DU) materials can be harmful, the greatest contamination danger from DU comes from its chemical toxicity rather than its radiological properties. DU can contaminate soil and water, posing risks to human health and the environment. Long-term exposure to DU particles can lead to various health issues, including potential cancer risks.
What are two common uses for depleted uranium?
DU mesh armor is used on most modern main battle tanks such as the US M1A2 Abrams, British Challenger 2, and German Leopard 2 (A4-A7). DU has been rumored to have been recently used in new armor piercing rounds, but they are largely unconfirmed.
Why are some bombs are poisonous?
Unless they're chemical ordnance, which are normally not authorized by treaty; conventional ordnance up until the Vietnam War were not generally poisonous. Post Viet War ordnance can be dangerous if using special "armor" defeating elements such as DU-Depleted Uranium.
Clothing and skin will block the majority of the alpha and beta particles from DU materials?
Yes, clothing and skin are effective barriers against alpha and beta particles emitted by depleted uranium (DU) materials. However, it's important to note that if DU particles are ingested or inhaled, they can pose a health risk regardless of protective barriers. Regular monitoring and appropriate safety measures should be in place when handling DU materials.
How do you make ammunition?
Depleted uranium (DU) is uranium primarily composed of the isotope uranium-238 (U-238). Natural uranium is about 99.27 percent U-238, 0.72 percent U-235, and 0.0055 percent U-234. U-235 is used for fission in nuclear reactors and nuclear weapons. Uranium is enriched in U-235 by separating the isotopes by mass. The byproduct of enrichment, called depleted uranium or DU, contains less than one third as much U-235 and U-234 as natural uranium. The external radiation dose from DU is about 60 percent of that from the same mass of natural uranium.[2] DU is also found in reprocessed spent nuclear reactor fuel, but that kind can be distinguished from DU produced as a byproduct of uranium enrichment by the presence of U-236.[3] In the past, DU has been called Q-metal, depletalloy, and D-38.DU is useful because of its very high density of 19.1 g/cm3. Civilian uses include counterweights in aircraft, radiation shielding in medical radiation therapy and industrial radiography equipment, and containers used to transport radioactive materials. Military uses include defensive armor plating and armor-piercing projectiles.The use of DU in munitions is controversial because of questions about potential long-term health effects.[4][5] Normal functioning of the kidney, brain, liver, heart, and numerous other systems can be affected by uranium exposure, because uranium is a toxic metal.[6] It is weakly radioactive and remains so because of its long physical half-life (4.468 billion years for uranium-238). The biological half-life (the average time it takes for the human body to eliminate half the amount in the body) for uranium is about 15 days.[7] The aerosol produced during impact and combustion of depleted uranium munitions can potentially contaminate wide areas around the impact sites leading to possible inhalation by human beings.[8] During a three week period of conflict in 2003 in Iraq, 1,000 to 2,000 tonnes of DU munitions were used.[9]The actual acute and chronic toxicity of DU is also a point of medical controversy. Multiple studies using cultured cells and laboratory rodents suggest the possibility of leukemogenic, genetic, reproductive, and neurological effects from chronic exposure.[4] A 2005 epidemiology review concluded: "In aggregate the human epidemiological evidence is consistent with increased risk of birth defects in offspring of persons exposed to DU."[10] The World Health Organization, the directing and coordinating authority for health within the United Nations which is responsible for setting health research norms and standards, providing technical support to countries and monitoring and assessing health trends,[11] states that no risk of reproductive, developmental, or carcinogenic effects have been reported in humans due to DU exposure.[12][13] This report has been criticized by Dr. Keith Baverstock for not including possible long term effects of DU on human body.
