Remains of toxic bullets litter Iraq
The Monitor finds high levels of radiation left by US armor-piercing shells.
At a roadside produce stand on the outskirts of Baghdad, business is brisk for Latifa Khalaf Hamid. Iraqi drivers pull up and snap up fresh bunches of parsley, mint leaves, dill, and onion stalks.Skip to next paragraph

But Ms. Hamid's stand is just four paces away from a burnt-out Iraqi tank, destroyed by - and contaminated with - controversial American depleted-uranium (DU) bullets. Local children play "throughout the day" on the tank, Hamid says, and on another one across the road.
No one has warned the vendor in the faded, threadbare black gown to keep the toxic and radioactive dust off her produce. The children haven't been told not to play with the radioactive debris. They gather around as a Geiger counter carried by a visiting reporter starts singing when it nears a DU bullet fragment no bigger than a pencil eraser. It registers nearly 1,000 times normal background radiation levels on the digital readout.
The Monitor visited four sites in the city - including two randomly chosen destroyed Iraqi armored vehicles, a clutch of burned American ammunition trucks, and the downtown planning ministry - and found significant levels of radioactive contamination from the US battle for Baghdad.
In the first partial Pentagon disclosure of the amount of DU used in Iraq, a US Central Command spokesman told the Monitor that A-10 Warthog aircraft - the same planes that shot at the Iraqi planning ministry - fired 300,000 bullets. The normal combat mix for these 30-mm rounds is five DU bullets to 1 - a mix that would have left about 75 tons of DU in Iraq.
The Monitor saw only one site where US troops had put up handwritten warnings in Arabic for Iraqis to stay away. There, a 3-foot-long DU dart from a 120 mm tank shell, was found producing radiation at more than 1,300 times background levels. It made the instrument's staccato bursts turn into a steady whine.
"If you have pieces or even whole [DU] penetrators around, this is not an acute health hazard, but it is for sure above radiation protection dose levels," says Werner Burkart, the German deputy director general for Nuclear Sciences and Applications at the UN's International Atomic Energy Agency (IAEA) in Vienna. "The important thing in any battlefield - especially in populated urban areas - is somebody has to clean up these sites."
Fresh-from-the-factory DU tank shells are normally handled with gloves, to minimize the health risk, and shielded with a thin coating. The alpha particle radiation emitted by DU travels less than an inch and can be stopped by cloth or even tissue paper. But when the DUmaterial burns (usually on impact; or as a dust, it can spontaneously ignite) protective shields disappear, and dangerous radioactive oxides are created that can be inhaled or ingested.
"[The risk] depends so very much on how you handle it," says Jan Olof Snihs, of Sweden's Radiation Protection Authority in Stockholm. In most cases dangers are low, he says, unless children eat toxic and radioactive soil, or get DU oxides on their hands.
Radioactive particles are a "special risk associated with a war," Mr. Snihs says. "The authorities should be aware of this, and try to decontaminate places like this, just to avoid unnecessary risk."
Pentagon officials say that DU is relatively harmless and a necessary part of modern warfare. They say that pre-Gulf War studies that indicated a risk of cancer and of causing harm to local populations through permanent contamination have been superseded by newer reports.
"There is not really any danger, at least that we know about, for the people of Iraq," said Lt. Col. Michael Sigmon, deputy surgeon for the US Army's V Corps, told journalists in Baghdad last week. He asserted that children playing with expended tank shells would have to eat and then practically suffocate on DU residue to cause harm.
But there is a growing chorus of concern among United Nations and relief officials, along with some Western scientific experts, who are calling for sites contaminated with DU be marked off and made safe.
