Toxic Effects of Inhalational Exposure to Uranium Oxide Dust Particles derived from Depleted Uranium Munitions
Armor Piercing Weapons, History Prior to WW II, Germany developed armor-piercing shells with tungsten carbide cores; these shells were a key to Erwin Rommel's early success in North Africa (1941-43).
Armor Piercing Weapons, History In the summer of 1943, anticipating a cut-off of tungsten imports from Portugal, Albert Speer, the German Armaments Minister authorized the production of armor-piercing shells made of uranium.
Armor Piercing Weapons, History These uranium shells proved not only to be effective armor-piercing munitions but they also had “an added incendiary effect" i.e. they often caused fires or explosions in the target. Because of this pyrophoric effect, Germans called uranium shells grenades: Panzer Grenat Patrone.
Armor Piercing Weapons, History In the late 1940s, the US DOD continued the development of kinetic energy penetrators made of uranium at the Aberdeen Proving Grounds. The first widespread battlefield use of depleted uranium penetrators was in Feb 1991 in the first Gulf War.
DU, Cancer, Leukemia and Birth Defects The 1991 use of DU weapons in southern Iraq was followed by a marked increase in birth defects, childhood leukemia and other cancers. the 2004 assaults on Falluja in central Iraq were followed by marked increases in birth defects, childhood leukemia and other cancers.
Fallujah - a timeline March 31, 2004 Ambush of 4 Blackwater contractors. April 4, 2004 1st assault on Fallujah begins. Nov. 4, 2004 2nd assault on Fallujah begins. These attacks on Fallujah involved more than 600 airstrikes. 2007: 1st reports of increases in pediatric leukemia. 2009: increases in birth defects reported in UK media. Pentagon position: No uranium munitions were used in Fallujah after July 2004. No records are available on the use of uranium munitions in Fallujah prior to July 2004.
Transgenerational Carcinogenesis an implausible concept?? suggested by some epidemiological data mouse experiments have documented only a few transgenerational carcinogens, the most recent being depleted uranium. The offspring of male mice exposed to depleted uranium have an increased frequency of gene mutations in their bone marrow. (AFRRI) Health Physics 99(3): 371-379, 2010 Sept

Organs of Uranium Oxide Uptake following Inhalational Exposure Lungs Kidneys Bones and Teeth Pulmonary Lymph Nodes
OVERVIEW of URANIUM TOXICOLOGY based on Literature Reviews and on the clinical symptoms of a small cohort of U.S. soldiers with documented inhalational exposures to DU dust in As Samawah (June-August 2003)
Individuals with a definite or probable inhalational exposure to uranium oxides and who have symptoms consistent with uranium toxicity may be plausibly considered to suffer from uranium toxicity.
DU has a unique isotope signature consequently, DU can be traced. The presence of DU in human urine or in tissues such as lung, lymph node, kidney, bone or teeth can be documented by Mass Spectroscopy. See R.R.Parrish et al.: Health Physics 90: 127-138, 2006 Feb.
Since 1996, the U.N. Sub-Commission on the Promotion and Protection of Human Rights has consistently ruled that Depleted Uranium weapons are incompatible with existing international humanitarian and human rights laws.
BANNED WEAPONS WMD weapons of mass destruction WIE weapons with indiscriminate effect WSI weapons which cause superfluous injury WUS weapons which cause unnecessary suffering
Uranium Oxide Dust derived from DU weapons: is inherently toxic is intrinsically indiscriminate damages the environment persists on the battlefield is not confined to the battlefield causes superfluous injury
U.N. Sub-Commision on the Promotion and Protection of Human Rights: Weapons Incompatible with existing International Law DU weapons Cluster bombs Fuel-air bombs Chemical weapons Bacteriological weapons Biological weapons
Optimal Penetration Requires Minimal area of impact (sharp tip) Maximal velocity (~1500 meters/sec) Maximal mass (density) High length to width ratio Optimal hardness
Uranium is carcinogenic lung tumors (dogs) lymphoma (monkeys) sarcomas (rats) transformation of osteoblasts(in vitro) excess lymphomas (uranium workers)
Uranium is mutagenic and genotoxic induces DNA damage in vitro increases revertants in the Ames test increases mutations in mammalian cells
Uranium is teratogenic Female mice that are exposed to uranium and subsequently become pregnant, show multiple reproductive toxicities including an increased frequency of congenital malformations.

Armor Piercing Weapons, History "In the summer of 1943, wolframite (tungsten) imports from Portugal were cut off, which created a critical situation for the production of solid core (anti-tank) ammunition. I thereupon ordered the use of uranium cores for this type of ammunition. My release of our uranium stocks of about 1200 metric tonnes showed that we no longer had any thought of producing atom bombs." Albert Speer, Minister of Armaments
