In 1990, the United Kingdom Atomic Energy Authority (UKAEA) wrote a report warning about the potential health and environmental catastrophe from the use of depleted uranium weapons. The health effects had been known for a long time. The report sent to the UK government warned "in their estimation, if 50 tonnes of residual DU dust remained ‘in the region’ there could be half a million extra cancers by the end of the century [2000]." Estimates of depleted uranium weapons used in 1991, now range from the Pentagon’s admitted 325 tons, to other scientific bodies who put the figure as high as 900 tons. That would make the number of estimated cancers as high as 9,000,000, depending on the amount used in the 1991 Gulf War. In the 2003 Gulf War, estimates of 2200 tons have been given — causing about 22,000,000 new cancer cases. Altogether the total number of cancer patients estimated using the UKAEA data would be 25,250,000. In July of 1998, the CIA estimated the population of Iraq to be approximately 24,683,313.
