SUMMARY: Depleted uranium (DU) is a low-cost radioactive material used for military armor and anti-armor munitions. The US military used DU ammunition on the battlefield for the first time during the Gulf War in 1991 to destroy light armored vehicles and bunkers. Hundreds of metric tons were released in Saudi Arabia, Kuwait and Iraq during Operation Desert Storm, where many vehicles were hit by friendly fire, or deliberately destroyed to avoid capture. DU ammunition was also used in Bosnia and Herzegovina in 1995, and in Yugoslavia in 1999, where over 1500 Tomahawk cruise missiles were launched, but its use was not publicly disclosed by the US government at the time. The US is currently using DU in the second war on Iraq, but will not disclose the quantities used. Many sites of widespread contamination have now been generated by the US world wide and here in the US., but regulations, treaties and international laws are unclear about the enforcement of remediation efforts against the US. Cancer is the expected long-term consequence of both radiological and toxic effects of DU exposure, especially on the vulnerable populations inhabiting the war zones generated by the US.
What is DU? History: DU is formed when highly radioactive, enriched uranium (for example, 234U used for nuclear energy), is depleted to a lower radioactive form, 238U. DU is preferred over tungsten for military use due to its availability and pyrophoricity, for it is a by-product of the US nuclear industry and so is provided to arms manufacturers at relatively low cost. It is desirable as a munition because it produces burning fragments upon impact and so can ignite flammable materials. It also can cause poisoning to humans through inhalation, ingestion and shrapnel wounds. Its half-life is 4.5 billion years.
During the Gulf War in 1991 it was used to destroy light armored vehicles and bunkers (over 1400 Iraqi tanks were reportedly hit by DU rounds). DU munitions include automatic cannon 30 mm rounds, MK149-4 Phalanx rounds, M919 rounds for Bradley fighting vehicles, Tomahawk land attack cruise missile tips, and land mines. An estimated 14,670 lbs of DU burned as result of fires in ammunition storage areas at the US army base at Doha, Kuwait. An estimated 305-340 metric tons of DU was released in Saudi Arabia, Kuwait and Iraq during Operation Desert Storm, where many vehicles were hit by friendly fire, or deliberately destroyed to avoid capture. These radioactive vehicles were buried in Saudi Arabia, shipped to decontamination facilities, and buried in low level radioactive waste dumps in the US. DU ammunition was also used in Bosnia and Herzegovina in 1995, and in Yugoslavia in 1999, where over 1500 Tomahawk cruise missiles were launched. DU is currently used in the second US war on Iraq, but the US government will not disclose the quantities used.
The use of DU was not publicly disclosed by the US government at its time of use, but finally revealed by a German scientist in 1992. US military officials have lied and misled the public about the scope and severity of exposures to veterans. The army failed to test Iraq I vets wounded by DU fragments until over one year after the first war in Iraq. Serious health and environmental studies did not begin until around 1994. It is estimated that between several hundred and several thousand US service members may have inhaled, been wounded by or otherwise been exposed to DU in Iraq, Kuwait and Saudi Arabia in the first US war on Iraq. The extent of the contamination due to the current US war on Iraq has not been revealed. The mainstream press and Congress are virtually silent regarding the rampant use and proliferation of this toxic material.
After the US began its scale up of DU munitions, other countries have taken up the practice. They now include Britain, France, Russia, Greece, Turkey, Israel, Saudi Arabia, Bahrain, Egypt, Kuwait, Pakistan, Thailand, South Korea, Taiwan and others that the Pentagon will not disclose. NRC export licenses reveal the US to be a major supplier of DU for military systems. Regulations, treaties and international laws are unclear about the ability to enforce remediation efforts against the US for causing widespread radioactive contamination. Cancer is the expected long-term consequence of both radiological and toxic effects of DU exposure, especially on the vulnerable populations inhabiting the war zones generated by the US.
DU Contamination DU contamination has been reported in water, soil, air, gas, plant and in animal life forms in war areas, manufacturing and testing sites throughout the U.S., as well as places distant from the war. Radiation detectors in Britain recorded a fourfold increase in uranium levels in the atmosphere after the shock and awe bombing campaign against Iraq in March 2003. This coincided with consistent air flow from Iraq northwards.
Field studies were made in Kosovo in November of 2000 to evaluate environmental contamination from DU ammunition during the 1999 conflict. Eleven out of 112 sites identified as places where DU ammunition had been fired were tested. Samples were collected by the Italian National Environmental Protection Agency in Kosovo in November of 2000 to evaluate the level of DU released into the environment. Soil samples showed uranium concentrations above environmental levels due to DU. Tree bark and lichen indicated its presence, and so are useful as sensitive qualitative bio-indicators for the presence of DU dusts or aerosols formed at times when DU ammunition had hit a hard target.
Soil and water at and around DU manufacturing and test sites have become contaminated throughout the US, generating Superfund contamination sites that will require massive funds for cleanup. In addition, insects, lizards and herbivorous mammals are showing DU accumulation.
Health Effects of DU DU has been shown to transform non-cancerous human cells to a cancerous state. It poses its greatest danger to human health when inhaled or ingested. It can be internalized as a result of breathing smoke containing DU particles, by hand to mouth transfer, as result of contact with contaminated surfaces, by inhalation or ingestion of contaminated food or water, and by contamination of wounds by contaminated dust or shrapnel. DU oxide aerosols formed during impact generate respirable size particles (less than 10 microns in diameter), generating water soluble forms of DU. Chronic exposure or long term ingestion of uranium by humans may produce interference with kidney function.
Elevated levels of uranium persist in the urine of DU-exposed Gulf War veterans seven years after exposure. Excretion is not significantly lowering the body burden of uranium. Five out of 22 samples from exposed veterans have detectable levels of uranium in their semen, and neurocognitive examinations demonstrated a lowered performance efficiency in contaminated veterans.
Concerns grow regarding the declining health of war participants and war victims. These include the non-specific health problems reported among Gulf War veterans, increased leukemia incidence among former peacekeeping soldiers in the Balkans, and increases in mortality and in leukemias in Iraqi. Childhood hematological malignancies increased in Croatia as result of war related events. Mortality rates among Iraqi children have increased sharply. The death rate per 1000 Iraqi children under 5 years of age increased by at almost 800% after US invasions of Iraq. Cases of lymphoblastic leukemia have more than quadrupled. Malignancies in children below 15 years of age in Basrah have increased by 300%, with leukemias among children in Basrah rising 350%. And, not surprisingly, congenital malformations in Basrah have increased by more than 500%.
