12/04/13: USA Today reports Mexican authorities on Wednesday recovered a truck and the radioactive medical equipment it was hauling when thieves stole it from a gas station two days ago. The radioactive material, cobalt-60, was found about a half-mile from the truck and its empty protective lead container near Mexico City, said Juan Eibenschutz, director general of the National Commission of Nuclear Safety and Safeguards. Radioactivity was detected in the area, which authorities cordoned off. Direct exposure to the radioactive isotope used in cancer treatment would result in death within a few minutes, Eibenschutz told the Associated Press. Eibenschutz said nothing indicated that the theft of the material was intentional or in any way intended for an act of terrorism. The material could not be used to make a nuclear bomb, but could be used in a dirty bomb, a conventional explosive that disseminates radioactive material, he said. Eibenschutz didn't know the exact weight, but that it was the largest amount stolen in recent memory, and the intensity of the material caused the alert. Local, state and federal authorities, including the military, are searching for the truck.
