the study your talking about was only a 6 month study. It also observed that it takes a lot less Uranium than previously thought to damage the brain.
There have also been other studys done showing that veterans with internally retained DU fragments might be more exposed to cancer and leukemia risks.
And even more studys document the damaging effects of uranium assumption on the reproductive cycle (reduced fertility, miscarriages, abortions, congenital defects at birth) of small laboratory mammals (mice, hamsters)...
The U.S. Army has commissioned some research into risks and harms of depleted uranium. Scientific documents produced by the Armed Forces Radiobiology Research Institute write of the "numerous unanswered questions about its [of DU] long term health effects", state that "moderate exposure to either DU or uranium presents a significant toxicological threat" [34] and strongly suggest "low dose DU induced carcinogenesis" which might affect military personnel following shrapnel wounds or inhalation [35]. The above mentioned research projects, in particular, focus on finding in advance complete toxicologic information for possible replacement materials for depleted uranium in projectiles, such as tungsten alloys, and on developing drugs capable of suppressing the biochemical process by which DU supposedly generates tumoral forms in the human body. The same institution is also working on methods allowing a more rapid and efficient detection of uranium contamination in human beings [36] and has developed a standardized procedure for medical assistance to military personnel exposed to depleted uranium contamination. [37]
You should also take a look at the stats from Iraq:
Following the first gulf war, scientists at the Basra hospital and university have monitored the incidence of leukaemias and other malignancies among children in the Basra area, and of congenital malformations in newborn children. The data for the period 1990-2001 show an incidence increase of 426% for general malignancies, 366% for leukemias and of over 600% for birth defects, with all series showing a roughly increasing pattern with time. These data, being the largest set of epidemiological data available for the Iraqi population, have received considerable attention; and since it reported a very large increase in those pathologies which are known or strongly suspected to be related to uranium poisoning, it has been natural to consider the possibility that such increase had indeed been caused by depleted uranium contamination. The connection, however, is far from being obvious or proven: first of all, there is a considerable delay (at least ten years) between the occurrence of contaminations and the peak of incidence of malformations and malignancies, which leads to speculative hypotheses about the process of accumulation of uranium in the human body; and secondarily, there could be other causes or concurrent causes, for example different kinds of pollution related or unrelated to the war (e.g. burning oil wells), or the 1990-2003 Iraq sanctions which led to a collapse of the Iraqi economy and in general to a dramatic impoverishment of the population with a sharp decrease of nutritional and hygienic conditions (which alone, however, cannot explain why the increase in congenital defects is the highest observed). In general, the prevailing scientific view on the matter [26],[27],[28] is that such data, and other scarce data available, do not conclusively prove a poisoning effect of depleted uranium; but that the possibility exists and cannot be ruled out either, and so a precautionary principle would suggest to suspend the use of such weapons.

It must be real easy to just dismiss something like this as a conspiracy theory. I guess that makes it easier for you to just close your eyes.

In 2001, a study was published in Military Medicine that found DU in the urine of Gulf War veterans [8]. Another study, published by Health Physics in 2004, also showed DU in the urine of Gulf War veterans [9]. A study of UK veterans who thought they might have been exposed to DU showed aberrations in their white blood cell chromosomes. [10] Mice immune cells exposed to uranium exhibit abnormalities [11].
Increases in the rate of birth defects for children born to Gulf War veterans have been reported. A 2001 survey of 15,000 U.S. Gulf War combat veterans and 15,000 control veterans found that the Gulf War veterans were 1.8 (fathers) to 2.8 (mothers) times as likely to report having children with birth defects [12]. In early 2004, the UK Pensions Appeal Tribunal Service attributed birth defect claims from a February 1991 Gulf War combat veteran to depleted uranium poisoning [37] [38].
In 2005, uranium metalworkers at a Bethlehem plant near Buffalo, New York, exposed to frequent occupational uranium inhalation risks, were alleged by non-scientific sources to have the same patterns of symptoms and illness as Gulf War Syndrome victims [39] [40].
In November, 2004, the anonymously-funded British inquiry headed by Lord Lloyd ([45]) concluded, for the first time, that thousands of UK and US Gulf War veterans were made ill by their service. The report claimed that Gulf veterans were twice as likely to suffer from ill health than if they had been deployed elsewhere, and that the illnesses suffered were the result of a combination of causes. These included multiple injections of vaccines, the use of organophosphate pesticides to spray tents, low level exposure to nerve gas, and the inhalation of depleted uranium dust. [46][47] The report was the first to suggest a direct link between military service in the Persian Gulf and illnesses suffered by veterans of that war and directly contradicts other theories which have suggested GWI is not a physical illness, but a response to the stresses of war.
Although not identifying Gulf War syndrome by name, in June of 2003 the High Court of England and Wales upheld a claim by Shaun Rusling that the depression, eczema, fatigue, nausea and breathing problems that he experienced after returning from the Gulf War were attributed to his military service.
A 2004 British study comparing 24,000 Gulf War veterans to a control group of 18,000 men found that those who had taken part in the Gulf war have lower fertility and are 40 to 50% more likely to be unable to start a pregnancy. Among Gulf war soldiers, failure to conceive was 2.5% vs. 1.7% in the control group, and the rate of miscarriage was 3.4% vs. 2.3%. These differences are small but statistically significant. [48]
In January 2006, a study led by Melvin Blanchard and published by the Journal of Epidemiology, part of the "National Health Survey of Gulf War-Era Veterans and Their Families", stated that veterans deployed in the Persian Gulf War had nearly twice the prevalence of chronic multisymptom illness (CMI), a cluster of symptoms similar to a set of conditions often called Gulf War Syndrome. [49]
Its certainly more than just a stupid conspiracy theory dont you think?
