How do we know it is from DU? Why can't it be pollution from Iraqi factories? Why can't it be other war materials? Why can't it be a pathogen from Saddam's programs? Why can't it be an outright lie from a disinfo team?

Antonio do you know of any studies? Is this all rumor at this point? I should think that someone is looking into this matter. Back here in the US the CDC should be charged with examining outbreaks including the health of families either military or civilian.

No. Not true at all.
What I see is an argument that DU is the cause. No proof is supplied only a claim. Again I see that someone thinks the material is radioactive. Again, a misleading statement.
Furthermore, I have posted several times that I believe the claim of the 3 headed baby to be a lie. I do not see anyone challenging that assertion.
Temperature issues arise for lead-free slug
By Matthew Cox - Staff writer
Posted : Monday Aug 10, 2009 17:40:21 EDT
The Army is scrapping the latest design for its eco-friendly 5.56mm ammo after some of the bullets began to show trajectory problems when exposed to hot temperatures.
Army ballistics officials halted production of the M855A1 Lead Free Slug ammunition in mid July, launched an investigation and decided to replace the bismuth-tin alloy slug with another material, said Lt. Col. Jeff Woods, product manager for Small Caliber Ammunition.
“We are currently evaluating alternate lead-free materials, and we will resume qualification once a selection is made,” Woods told Army Times.
In the M855A1 LFS bullet’s design, the bismuth-tin alloy sits beneath a steel penetrating tip. A copper jacket encases all but the point of the bullet. The round was designed to work specifically with the M4 carbine. Army officials have maintained that the new round will provide more “consistent performance” than the current M855 round and perform better against hard targets.
The problem surfaced when some of the bullets did not follow their trajectory or planned flight path.
“During ballistic testing of production LFS cartridges, we noticed that some projectiles occasionally varied from the intended trajectory,” Woods said.
The plan was to start issuing the first of 20 million rounds in August, replacing the standard M855 lead round.
One thing the Army is sure of is that “this will delay fielding of the new round,” Woods said.
This is not the first hiccup to occur in the quest for lead-free ammunition, a program the Army has invested tens of millions of dollars in since the mid-1990s.
The Corps has dropped its plans to field the Army’s M855A1 and approved the new SOST round for Marines to use in Afghanistan. SOST, short for Special Operations Science and Technology, is SOCom’s enhanced 5.56mm round . It isn’t green, but it is deadlier than the current M855 round and it’s available now, Marine officials say. The Corps’ decision to purchase about 2 million SOST rounds in September illustrates the growing frustration with the M855’s performance on the modern battlefield.
Types of 30 mm ammunition
30 mm ammunition generally comes in three varieties: armor piercing (AP), high explosive (HE), and training rounds. Armor piercing and high explosive cartridges usually also possess incendiary characteristics. Anti-material and armor piercing rounds use depleted uranium to pierce armor.[citation needed] When the depleted uranium hits the metal at high speed, the kinetic energy ignites the uranium particles that contact oxygen. After hitting, the depleted uranium leaves low levels of radiation on the target.[citation needed] To avoid this, tungsten may be used instead, as it is not a radioactive material, but its price is far greater than depleted uranium.[citation needed]

The use of DU in munitions is controversial because of questions about potential long-term health effects. Normal functioning of the kidney, brain, liver, heart, and numerous other systems can be affected by uranium exposure, because in addition to being weakly radioactive, uranium is a toxic metal. It is weakly radioactive and remains so because of its long half-life (4.468 billion years for uranium-238). The aerosol produced during impact and combustion of depleted uranium munitions can potentially contaminate wide areas around the impact sites or can be inhaled by civilians and military personnel. During a three week period of conflict in 2003 in Iraq, 1,000 to 2,000 tonnes of DU munitions were used, mostly in cities.
Have there been accidents involving uranium hexafluoride?
There have been several accidents involving uranium hexafluoride in the United States. Summaries of the larger accidents are given in the following paragraphs.
In 1944, a research and development pilot plant for thermal diffusion was temporarily shut down for piping modifications. During reactivation of the plant, a weld ruptured on an 8-ft long cylinder containing gaseous natural UF6 that was being heated by steam. An estimated 400 lb of UF6 was released, which reacted with steam from the process and created HF and uranyl fluoride. This accident resulted in two deaths from HF inhalation and three individuals seriously injured from both HF inhalation and uranium toxicity. The injured individuals eventually recovered, and a follow-up many years later showed no evidence of lasting kidney damage from the uranium exposure.
In 1978 a cylinder containing liquid depleted UF6 was accidentally dropped and ruptured in a storage yard at the Portsmouth Gaseous Diffusion Plant. Cold weather limited the dispersion of the UF6. Cleanup efforts were conducted to collect as much of the released material as possible. No one was injured in this accident. (Note: Storage cylinders contain liquid UF6 only for a few days immediately after filling. Once the cylinder cools the UF6 is a solid and would be released much more slowly if an accident resulted in cylinder rupture).
Another UF6 accident involving a cylinder rupture occurred at a commercial uranium conversion facility (Sequoyah Fuels Corp., Gore OK) in 1986. The accident occurred when an over-loaded shipping cylinder was reheated to remove an excess of UF6. The cylinder ruptured, releasing a dense cloud of UF6 and its reaction products. This accident resulted in the death of one individual from HF inhalation. An additional 31 workers were exposed to the released cloud. Although some of the more highly exposed workers showed evidence of short-term kidney damage (e.g., protein in the urine), none of these workers had lasting kidney toxicity from the uranium exposure.
In addition to these accidents, ten depleted UF6 cylinders containing solid UF6 in storage have been breached over the past 45 years. Most of the breaches were due to corrosion around dents caused by mishandling, with the others due to corrosion around welding defects or from external corrosion alone. Additional information concerning cylinder breaches can be found under the question "What happens if a cylinder of uranium hexafluoride leaks?"
About 95% of the depleted uranium produced to date is stored as uranium hexafluoride, DUF6, in steel cylinders in open air yards close to enrichment plants. Each cylinder contains up to 12.7 tonnes (or 14 US tons) of solid UF6. In the U.S. alone, 560,000 tonnes of depleted UF6 had accumulated by 1993. In 2005, 686,500 tonnes in 57,122 storage cylinders were located near Portsmouth, Ohio, Oak Ridge, Tennessee, and Paducah, Kentucky.[2][3] The long-term storage of DUF6 presents environmental, health, and safety risks because of its chemical instability. When UF6 is exposed to moist air, it reacts with the water in the air to produce UO2F2 (uranyl fluoride) and HF (hydrogen fluoride) both of which are highly soluble and toxic. Storage cylinders must be regularly inspected for signs of corrosion and leaks. The estimated life time of the steel cylinders is measured in decades.[4]
Can you not read? That's not my damn name. I don't have a penis.
it releases radioactive particles and toxic material & dust into the air.
