"The U.S. Military and its supporters regularly quote a Rand Corp. Study which uses the natural uranium inhaled by miners.
Particles smaller than 10 microns can access the innermost recesses of lung tissue where they become permanently lodged. Furthermore, if the substance is relatively insoluble, such as the ceramic DU-oxide dust produced from burning DU, it will remain in place for decades, dissolving very slowly into the bloodstream and lymphatic fluids through the course of time. Studies have identified DU in the urine of Gulf War veterans nine years after that conflict, testifying to the permanence of ceramic DU-oxide in the lungs. Thus the effects are far different from natural uranium dust, whose coarse particles are almost entirely excreted by the body within 24 hours.
The military is aware of DU's harmful effects on the human genetic code. A 2001 study of DU's effect on DNA done by Dr. Alexandra C. Miller for the Armed Forces Radiobiology Research Institute in Bethesda, Md., indicates that DU's chemical instability causes 1 million times more genetic damage than would be expected from its radiation effect alone.
Studies have shown that inhaled nano-particles are far more toxic than micro-sized particles of the same basic chemical composition. British toxicopathologist Vyvyan Howard has reported that the increased toxicity of the nano-particle is due to its size.
For example, when mice were exposed to virus-size particles of Teflon (0.13 microns) in a University of Rochester study, there were no ill effects. But when mice were exposed to nano-particles of Teflon for 15 minutes, nearly all the mice died within 4 hours.
"Exposure pathways for depleted uranium can be through the skin, by inhalation, and ingestion," writes Lauren Moret, another DU researcher. "Nano-particles have high mobility and can easily enter the body. Inhalation of nano-particles of depleted uranium is the most hazardous exposure, because the particles pass through the lung-blood barrier directly into the blood.
"When inhaled through the nose, nano-particles can cross the olfactory bulb directly into the brain through the blood brain barrier, where they migrate all through the brain," she wrote. "Many Gulf era soldiers exposed to depleted uranium have been diagnosed with brain tumors, brain damage and impaired thought processes. Uranium can interfere with the mitochondria, which provide energy for the nerve processes, and transmittal of the nerve signal across synapses in the brain.
Based on dissolution and excretion rate data, it is possible to approximate the amount of DU initially inhaled by these veterans. For the handful of veterans studied, this amount averaged 0.34 milligrams. Knowing the specific activity (radiation rate) for DU allows one to determine that the total radiation (alpha, beta and gamma) occurring from DU and its radioactive decay products within their bodies comes to about 26 radiation events every second, or 800 million events each year. At .34 milligrams per dose, there are over 10 trillion doses floating around Iraq and Afghanistan.
How many additional deaths are we talking about? In the aftermath of the first Gulf War, the UK Atomic Energy Authority came up with estimates for the potential effects of the DU contamination left by the conflict. It calculated that "this could cause "500,000 potential deaths". This was "a theoretical figure", it stressed, that indicated "a significant problem".
The AEA's calculation was made in a confidential memo to the privatized munitions company, Royal Ordnance, dated 30 April 1991. The high number of potential deaths was dismissed as "very far from realistic" by a British defense minister, Lord Gilbert. "Since the rounds were fired in the desert, many miles from the nearest village, it is highly unlikely that the local population would have been exposed to any significant amount of respirable oxide," he said. These remarks were made prior to the more recent invasions of both Afghanistan and Iraq, where DU munitions were used on a larger scale in and near many of the most populated areas.
If the amount of DU ordinance used in the first Gulf War was sufficient to cause 500,000 potential deaths, (had it been used near the populated areas), then what of the nearly six times that amount used in operation Iraqi Freedom, which was used in and near the major towns and cities? Extrapolating the U.K. AEA estimate with this amount gives a figure of potentially 3 million extra deaths from inhaling DU dust in Iraq alone, not including Afghanistan. This is about 11% of Iraq's total population of 27 million. Dan Bishop, Ph.d chemist for IDUST feels that this estimate may be low, if the long life of DU dust is considered. In Afghanistan, the concentration in some areas is greater than Iraq.
What can an otherwise healthy person expect when inhaling the deadly dust? Captain Terry Riordon was a member of the Canadian Armed Forces serving in Gulf War I. He passed away in April 1999 at age 45. Terry left Canada a very fit man who did cross-country skiing and ran in marathons. On his return only two months later he could barely walk.
He returned to Canada in February 1991 with documented loss of motor control, chronic fatigue, respiratory difficulties, chest pain, difficulty breathing, sleep problems, short-term memory loss, testicle pain, body pains, aching bones, diarrhea, and depression. After his death, depleted uranium contamination was discovered in his lungs and bones. For eight years he suffered his innumerable ailments and struggled with the military bureaucracy and the system to get proper diagnosis and treatment. He had arranged, upon his death, to bequeath his body to the UMRC. Through his gift, the UMRC was able to obtain conclusive evidence that inhaling fine particles of depleted uranium dust completely destroyed his heath. How many Terry Riordans are out there among the troops being exposed, not to mention Iraqi and Afghan civilians?

I think any report coming from Rand corp. and Military.com should be taken with a grain of salt. From you guys it sounds as if depleted uranium is just the stuff to sprinkle on your cereals.
