"When highly radioactive material that can be used in a 'dirty bomb' is moved to or from a hospital in New York City, it is done in the dead of night on cordoned streets with high security."
"In Mexico two weeks ago, a truck moving a large canister containing radioactive material was hijacked at a gas station — where it had been parked with no security. The cobalt-60 that was stolen from the vehicle and then extracted from its protective lead shield is so potent that it is considered a significant national security threat under U.S. guidelines.
There are now no international mandatory requirements for how to control these dangerous materials — including how they should be transported. The International Atomic Energy Agency (IAEA), the international nuclear watchdog, has only issued recommendations, in the form of a voluntary Code of Conduct.This disconnect between how nations manage extremely dangerous nuclear materials sought by terrorists creates significant security vulnerabilities. If a dirty bomb is exploded anywhere in the world, it would cross the nuclear terrorism threshold and open the door to further attacks."
