Swallowing it is actually safer than breathing it, go figure. Plutonium and many other radioactives are similar. If you ate some plutonium you would end up dying from it's chemical toxicity but not be too harmed otherwise. :-) There was a recorded case of a worker swallowing a pellet of Am-232 at a factory that makes smoke detectors. Passed through intact and was just fine.
