ICAN is launching a report revealing that the healthcare systems in ten major cities around the world would be desperately overwhelmed by the immediate impact of the detonation of just one nuclear weapon. The study models the detonation of one 100-kiloton airburst nuclear explosion over major cities in each of the nine nuclear-armed states and Germany, which hosts U.S. nuclear weapons on its territory. It then examines how many hospital beds, doctors, nurses and where information is available, ICU beds and burn care centres would be left to treat hundreds of thousands to over one million injured people.
