Five Mexican states were put on alert Sunday after a truck carrying a container of potentially dangerous radioactive material was stolen, the interior ministry said.
The National Coordination of Civil Protection issued the warning after a company in the central state of Queretaro reported that a pick-up truck carrying radioactive iridium-192 had been stolen.
Officials said the radioactive material represented a significant health risk if taken outside its container, but was not dangerous if kept sealed.
Iridium-192 can cause burns, radiation sickness and permanent injury if a person comes in contact with it, and can be fatal if exposure lasts hours or days.
Authorities asked that anyone who comes across the radioactive material to notify officials immediately, not touch it and stay clear of it by a 30-meter (100-foot) perimeter.
Theft of radioactive material is not uncommon in Mexico. In April of last year a container carrying iridium-192 was stolen and recovered a week later in southeastern Mexico, the fourth such theft since 2013.
