MEXICO CITY (AP) — A missing shipment of radioactive cobalt-60 was found Wednesday near where the stolen truck transporting the material was abandoned in central Mexico, the country’s nuclear safety director said.
The highly radioactive material had been removed from its container, officials said, and one predicted that anyone involved in opening the box could be in grave danger of dying within days.

“The person or people who this took out are in very great risk of dying,” Jimenez said, adding that the normal survival rate would be between one and three days.
He said there was no word so far of anyone reporting to area hospitals with radiation exposure. He said those who exposed themselves to the pellets could not contaminate others.
This scenario reminds me of the movie, Act of Valor, via USA Today:
The U.N. nuclear agency says a truck carrying an extremely dangerous radioactive substance has been stolen in Mexico.
The International Atomic Energy Agency says the truck was carrying cobalt-60, used for radiotherapy treatment to combat cancer. An IAEA statement Wednesday said the truck was stolen Monday while taking the material to a radioactive waste storage center from the northern city of Tijuana.
