The facts about DU

DU munitions were first used in the Gulf War of 1991. A total of 320 tons (290,300 kilograms) of DU projectiles were fired by the US during the Gulf War. DU friendly fire and accidental fire incidents contaminated a total of 31 US combat vehicles (16 Abrams tanks and 15 Bradley armored vehicles) in the Gulf during 1990-1991. These incidents, and the resultant cleanup and recovery operations, exposed a number of soldiers to depleted uranium. Those with the highest exposures were in, on, or near vehicles when they were struck.

US Air Force A-10 Thunderbolt II aircraft fired approximately 10,000 30mm DU rounds (3.3 tons of DU) at 12 sites in Bosnia-Herzegovina in 1994-1995. In 1999, they fired nearly 31,000 DU rounds (10.2 tons of DU) at 85 sites in Kosovo.

Health Issues
The major health concerns about DU relate to its chemical properties as a heavy metal rather than to its radioactivity, which is very low. As with all chemicals, the hazard depends mainly upon the amount taken into the body. Medical science recognizes that uranium at high doses can cause kidney damage. However, those levels are far above levels soldiers would have encountered in the Gulf or the Balkans.

Because depleted uranium emits primarily alpha radiation, it is not considered a serious external radiation hazard. The depleted uranium in armor and rounds is covered, further reducing the radiation dose. When breathed or eaten, small amounts of depleted uranium are carried in the blood to body tissues and organs; much the same as the more radioactive natural uranium. Despite this, no radiological health effects are expected because the radioactivity of uranium and depleted uranium are so low.

Most soldiers and civilians will not be exposed to dangerous levels of depleted uranium. However, in certain circumstances the exposures may be high and there would be a risk of heavy metal poisoning that could lead to long-term kidney damage for a few soldiers, as well as the increased risk of lung cancer. A small number of soldiers and civilians might suffer kidney damage from depleted uranium if substantial amounts are breathed in, or swallowed in contaminated soil and water. The kidneys of a few soldiers may be damaged if they inhale large quantities of DU after their vehicle is struck by a penetrator or while working for long periods in contaminated vehicles. Large numbers of corroding DU penetrators buried in the soil may also pose a long-term threat if uranium leaches into water supplies. Long-term sampling, particularly of water and milk, is required to detect any increase in uranium levels around areas where DU has been used on the battlefield.

Anecdotal reports of deaths and illnesses among US veterans of the Gulf War who worked for long periods in heavily contaminated vehicles prompted a number of investigations. The voluntary Veterans Affairs DU Medical Follow-up Program began in 1993-1994 with the medical evaluations of 33 friendly-fire DU-exposed veterans, many with embedded DU fragments. An additional 29 of the friendly-fire victims were added to the follow-up program in 1999. In 1998, the scope of the program was expanded to include Gulf War veterans who may have been exposed to DU through close contact with DU munitions, inhalation of smoke containing DU particulate during a fire at the Doha depot, or by entering or salvaging vehicles or bunkers that were hit with DU projectiles. The published results of these medical evaluations indicate that the presence of retained DU fragments is the only scenario predictive of a high urine uranium level, and those with embedded DU fragments continue to have elevated urine uranium levels ten years after the incident. It is unlikely that an individual without embedded DU fragments would have an elevated urine uranium level, and consequently any uranium-related health effects.

In late 2000 and early 2001, various news reports, mostly European, reported allegations of an increase in leukemia cases related to exposure to DU while serving in the Balkans. Subsequent independent investigations by the World Health Organization, European Commission, European Parliament, United Nations Environment Programme, United Kingdom Royal Society, and the Health Council of the Netherlands have all have discounted any association between depleted uranium and leukemia or other medical problems among Balkans veterans.
