In the wake of America's "shock and awe" bombing campaign to take Baghdad, radiation detectors as far away as the United Kingdom noticed a fourfold spike in radioactivity in the atmosphere. At the time, the Department of Defense bragged that the substance, a nuclear byproduct with a fraction of the radioactivity as standard uranium, is commonly ingested by Americans, in food, drinking water and the air, allegedly with no ill effects. Officials went on to say its use would cause "no impact on the health of people and the environment."
Today, according to a study by the International Journal of Environmental Research and Public Health [PDF link], rates of cancer, leukemia, infant mortality and sexual mutations in Fallujah are higher than those reported in the aftermath of the Hiroshima and Nagasaki nuclear detonations.
