A look at recent nuclear-material incidents
Nuclear material was stolen from a truck in Mexico this week before being recovered two days later. Such incidents are alarmingly frequent. More than 20 cases of theft or loss of nuclear material take place every year, according to the IAEA. Many are never publicly reported. These are selected cases from the past 10 years, based on reports tracked by the Nuclear Threat Initiative.
