.On December 2, 2013, a vehicle transporting a teletherapy source from the IMSS Hospital in Tijuana, Baja California (Co-60 approximately 3000 Ci, Category I) to the Radioactive Waste Storage Center (CADER) in Maquixco, Mexico State was stolen near a gas station in the Municipality of Tepojaco, Hidalgo.
Law enforcement authorities tracked the teletherapy device down to a field near the town of Hueypoxtla in Mexico State, very close to where the truck was stolen, at around 14:00 (20:00 UTC) on 4 December 2013.
The radioactive cobalt-60 source had been removed from its protective shielding, but there were no indication that it had been damaged or broken up and no there were no signs of contamination to the area. The source was secured by the authorities.
One member of the public is undergoing medical assessment in Mexico City after presenting himself with skin damage indicating overexposure to the source by carrying it over one shoulder.
