Iridium-192: how dangerous is it?
Quote:
We're all going to die! Calm down. There is a lot of unaccounted-for iridium-192 in the world ? in the US particularly ? but this a relatively small amount, and it is probable the thief or thieves don't even know what they have.
Is it dangerous? It should be safe as long as it remains in its lead-shielded casing. In the meantime, police are appealing to the public to keep an eye out for the missing canister.
Do say: "Don't worry. Unlike some radioactive isotopes, iridium-192 loses its potency quite quickly. No respectable dirty-bomb maker would touch it."

I hope this is correct
