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.

The molar enthalpy of vaporization of benzene at its boiling point 353.25 K is 30.8 kJ mol-1 What is the molar internal energy change?
It should be 0 as internal energy is a function of temperature, i.e: U (T) At the boiling point, there is no change in temperature, and hence DU= 0
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?
Uranium is toxic and radioactive; the primary health risk is the inhalation of fine powders; this can be after many years a cause of lung cancers.
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).
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.
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.
How is propane harvested?
Usual forms of mining are used to obtain (say) uranium ore, which is then refined into yellow cake. This then is further refined to extract the isotopes most useful as a nuclear fuel.The waste uranium is used as DU Depleted Uranium for bullets, and ship keels. It has a high penetration, and is 'self-sharpening' in bullet use. This is not a benign material because of radioactivity, particularly as a dust breathed in. .If one wishes bomb-grade fuel, this is refined as uranium hexafluoride, by a series of centrifuges, and is an expensive process.Other materials are suitable as reactor fuel, but as they do not produce weapons-grade by-products, they are ignored at the moment. Thorium would be in the vanguard here.
What kind of metal are water tanks made from?
Steel, an alloy of iron, carbon and some other metals, is the primary metal used to construct a battle tank. There will be a number of other metals (and alloys) used to make different parts around and inside this armored vehicle, and they include aluminum, brass, copper, titanium, uranium (the depleted type, or DU) and others.
