Why do people think Depleted Uranium Rounds kill our own troops? Ever meet a Uranium miner? I have. He's OK.

Question

Sure they might kill our troops if they were shot with one. We use them becasue the WORK! An extra half mile away is a nice advantage. SURE they break things and hurt people. It's a damned cannon shell! Photos of dead enemy troops are a testament to their effectiveness. Great! Better than having to hit that tank 2 or 3 times closer up and endanger our people. Some people don't mind that. I do. Ever get a tooth x-ray (80 MR exposure)? Ever live or work in a cement building with no windows (Basement, factory)? The you are exposed to Radon gas! How about getting a sun tan? An afternoon of that will expose you to more radioactivity than I, as a nuke worker am alowed to get on the job in 90 days! Sure we use DR rounds. But we are not the only ones. I think Russia invented them. All old Com-bloc nations have them in their ammo cans. They've been around for a while because they WORK! One shot one kill ... of THEM not us!
North Korea has several Uranium Mines. Wonder what they do with it all.

Depleted uranium

The uranium remaining after removal of the enriched fraction contains about 99.8% 238U, 0.2% 235U and 0.001% 234U by mass; this is referred to as depleted uranium or DU.
The main difference between DU and natural uranium is that the former contains at least three times less 235U than the latter.
DU, consequently, is weakly radioactive and a radiation dose from it would be about 60% of that from purified natural uranium with the same mass.
The behaviour of DU in the body is identical to that of natural uranium.
Spent uranium fuel from nuclear reactors is sometimes reprocessed in plants for natural uranium enrichment. Some reactor-created radioisotopes can consequently contaminate the reprocessing equipment and the DU. Under these conditions another uranium isotope, 236U, may be present in the DU together with very small amounts of the transuranic elements plutonium, americium and neptunium and the fission product technetium-99. However, the additional radiation dose following intake of DU into the human body from these isotopes would be less than 1%.
Applications of depleted uranium

Due to its high density, about twice that of lead, the main civilian uses of DU include counterweights in aircraft, radiation shields in medical radiation therapy machines and containers for the transport of radioactive materials. The military uses DU for defensive armour plate.
DU is used in armour penetrating military ordnance because of its high density, and also because DU can ignite on impact if the temperature exceeds 600°C.
Exposure to uranium and depleted uranium

Under most circumstances, use of DU will make a negligible contribution to the overall natural background levels of uranium in the environment. Probably the greatest potential for DU exposure will follow conflict where DU munitions are used.
A recent United Nations Environment Programme (UNEP) report giving field measurements taken around selected impact sites in Kosovo (Federal Republic of Yugoslavia) indicates that contamination by DU in the environment was localized to a few tens of metres around impact sites. Contamination by DU dusts of local vegetation and water supplies was found to be extremely low. Thus, the probability of significant exposure to local populations was considered to be very low.
A UN expert team reported in November 2002 that they found traces of DU in three locations among 14 sites investigated in Bosnia following NATO airstrikes in 1995. A full report is expected to be published by UNEP in March 2003.
Levels of DU may exceed background levels of uranium close to DU contaminating events. Over the days and years following such an event, the contamination normally becomes dispersed into the wider natural environment by wind and rain. People living or working in affected areas may inhale contaminated dusts or consume contaminated food and drinking water.
People near an aircraft crash may be exposed to DU dusts if counterweights are exposed to prolonged intense heat. Significant exposure would be rare, as large masses of DU counterweights are unlikely to ignite and would oxidize only slowly. Exposures of clean-up and emergency workers to DU following aircraft accidents are possible, but normal occupational protection measures would prevent any significant exposure.
Intake of depleted uranium


Average annual intakes of uranium by adults are estimated to be about 0.5mg (500 μg) from ingestion of food and water and 0.6 μg from breathing air.
Ingestion of small amounts of DU contaminated soil by small children may occur while playing.
Contact exposure of DU through the skin is normally very low and unimportant.
Intake from wound contamination or embedded fragments in skin tissues may allow DU to enter the systemic circulation.
Absorption of depleted uranium

About 98% of uranium entering the body via ingestion is not absorbed, but is eliminated via the faeces. Typical gut absorption rates for uranium in food and water are about 2% for soluble and about 0.2% for insoluble uranium compounds.
The fraction of uranium absorbed into the blood is generally greater following inhalation than following ingestion of the same chemical form. The fraction will also depend on the particle size distribution. For some soluble forms, more than 20% of the inhaled material could be absorbed into blood.
Of the uranium that is absorbed into the blood, approximately 70% will be filtered by the kidney and excreted in the urine within 24 hours; this amount increases to 90% within a few days.
Potential health effects of exposure to depleted uranium

In the kidneys, the proximal tubules (the main filtering component of the kidney) are considered to be the main site of potential damage from chemical toxicity of uranium. There is limited information from human studies indicating that the severity of effects on kidney function and the time taken for renal function to return to normal both increase with the level of uranium exposure.
In a number of studies on uranium miners, an increased risk of lung cancer was demonstrated, but this has been attributed to exposure from radon decay products. Lung tissue damage is possible leading to a risk of lung cancer that increases with increasing radiation dose. However, because DU is only weakly radioactive, very large amounts of dust (on the order of grams) would have to be inhaled for the additional risk of lung cancer to be detectable in an exposed group. Risks for other radiation-induced cancers, including leukaemia, are considered to be very much lower than for lung cancer.
Erythema (superficial inflammation of the skin) or other effects on the skin are unlikely to occur even if DU is held against the skin for long periods (weeks).
No consistent or confirmed adverse chemical effects of uranium have been reported for the skeleton or liver.
No reproductive or developmental effects have been reported in humans.
Although uranium released from embedded fragments may accumulate in the central nervous system (CNS) tissue, and some animal and human studies are suggestive of effects on CNS function, it is difficult to draw firm conclusions from the few studies reported.

In otherwords Depleted uranium would not cause radiation poisoning unless you were rolling around Naked in huge piles of it while eating it.

Answer 2

Depleted Uranium is not used in anti personnel rounds. It is used because of it's ARMOR PIERCING abilities. There isn't enough radioactive material in the ALLOY to hurt anything, it's only used in a quantity required to make the steel harder than normal steel.

Depleted Uranium in no way has the ability to make a bullet fly faster or farther, it ONLY makes the bullet harder.

Answer 3

Depeleted Uranuim is also used in Control Surface Counterweights on larger transports such as the C-5.

Answer 4

More hypocrisy from the US of A.. Depleted uranium as a weapon is almost as good at causing destruction as atomic bombs are (they ARE nuclear weapons, after all).. Thus the US owns and USES WMDs. Lets go in and hang Bush.

Waits for all the Bushservatives to thumbs-down me.

Answer 5

Depleted uranium rounds are denser than conventional ammunition which allows them better penetration capabilities. It has nothing to do with radiation.

Answer 6

The Liberal Spinmiesters at work again.....
The small amount and the ways it used offer very little threat...unless you are on the business end of a projectile...
