    And everyone alive is “full of” radioactive waste from nuclear bomb tests in the 60’s. And by “full of” I mean, technically detectable by extremely precise scientific equipment but in such small quantities that it has zero effect on the organism and is measured by the number of molecules present rather than even something small like micrograms.

      @I_Has_A_Hat This, by the way, is why someone has been stealing pre-'40s shipwrecks off the ocean floors. That’s the only easily accessible iron that’s not contaminated with ‘bomb waste’, making it valuable for certain kinds of scientific instruments. But no one cares about all the iron we use everyday in everything, because the level is so low.

      @I_Has_A_Hat You’re mostly correct, but it’s a bit more than that. ‘Radiation’ is a lot of things (heat, light, etc.), but what we mean in cases like this is IONIZING radiation. And our world is filled with that. Bananas are radioactive, for example. Your own body is, too, only because it also contains some potassium-40. Anything granite you encounter is slightly radioactive, and so on. This does not require us to ingest waste from bombs, but that’s also a factor.
