Chris Busby, co-author of the epidemiological study “Cancer, Infant Mortality and Birth Sex-Ratio in Fallujah, Iraq 2005–2009,” discusses the difficulties of carrying out a door-to-door survey of skeptical and hostile Fallujah residents, the severe birth deformities in regions where depleted uranium munitions were used, the study’s focus on infant mortality rates, the military’s outdated risk modeling for battlefield uranium exposure and why a dramatically lower male birth rate is a telling sign of regional genetic damage.
