Studies in 2005 and earlier have concluded that DU ammunition has no measurable detrimental health effects.
A 1999
literature review conducted by the
Rand Corporation stated: "No evidence is documented in the literature of cancer or any other negative health effect related to the radiation received from exposure to depleted or natural uranium, whether inhaled or ingested, even at very high doses,"
[106] and a RAND report authored by the U.S. Defense department undersecretary charged with evaluating DU hazards considered the debate to be more political than scientific.
[107]
A 2001
oncology study concluded that "the present scientific consensus is that DU exposure to humans, in locations where DU ammunition was deployed, is very unlikely to give rise to
cancer induction".
[108] Former
NATO Secretary General Lord Robertson stated in 2001 that "the existing medical consensus is clear. The hazard from depleted uranium is both very limited, and limited to very specific circumstances".
[109]
A 2002 study from the
Australian defense ministry concluded that Āthere has been no established increase in mortality or morbidity in workers exposed to uranium in uranium processing industries... studies of Gulf War veterans show that, in those who have retained fragments of depleted uranium following combat related injury, it has been possible to detect elevated urinary uranium levels, but no kidney toxicity or other adverse health effects related to depleted uranium after a decade of follow-up.Ā
[110] Pier Roberto Danesi, then-director of the
IAEA Seibersdorf +Laboratory, stated in 2002 that "There is a consensus now that DU does not represent a health threat".
[111]
The
International Atomic Energy Agency reported in 2003 that, "based on credible scientific evidence, there is no proven link between DU exposure and increases in human cancers or other significant health or environmental impacts," although "Like other heavy metals, DU is potentially poisonous. In sufficient amounts, if DU is ingested or inhaled it can be harmful because of its chemical toxicity. High concentration could cause kidney damage." The IAEA concluded that while depleted uranium is a potential
carcinogen, there is no evidence that it has been carcinogenic in humans.
[112]
A 2005 study by
Sandia National LaboratoriesĀ Al Marshall used mathematical models to analyze potential health effects associated with accidental exposure to depleted uranium during the 1991 Gulf War. MarshallĀs study concluded that the reports of cancer risks from DU exposure are not supported by veteran medical statistics, but Marshall did not consider reproductive health effects.
