The way I understand it, booster rockets blow up on takeoff sometimes, with on the order of 1 in a hundred frequency (how many shuttle flights preceeded Challenger?). Plutonium is their fuel of choice, tens of kilograms per vehicle. Plutonium dust is fatal in very small doses, micrograms. So that's conservatively a billion lethal doses per vehicle. Atmospheric dynamics have been shown to efficiently distribute small particles globally.
I don't want to catch a lungfull of that stuff when somebody forgets to convert their units, or asks "what's that button do?".
