I'm quite curious what the circumstances of that would have been. I looked it up because I thought I was mistaken, but ya: it's nuclear reactor byproduct and itself capaple of being turned into a nuclear weapon (or only some isotopes maybe? Not sure). It also apparently is capable of just starting on fire in open air, is poisonous, radioactive obviously and accumulates in the bones. Sounds like fun stuff.
