Seems that caesium-137 is also excreted pretty quickly: https://en.m.wikipedia.org/wiki/Caesium-137 https://en.m.wikipedia.org/wiki/Caesium-137 Still even though it's hard to find good numbers, and the average seems to be ~ banana / kg. I believe there's at least reports of mushrooms and boars with ~10-100 times the radiation of an average banana. I don't think it's actually possible to show any health effects of that amount of radiation, even if ingested (and excreted) but it's more than the average banana.
