FYI: unprocessed uranium isn't radioactive enough to do a lot of harm. At least as eaten. BUT uranium is incredibly toxic as a heavy metal so it'd still kill you quickly.

What do you mean you don't have a nuclear reactor in your stomach?

I never got this analysis, doesn't any material have absurd energy if you break down its very molecules and atoms?

Funny enough they aren't wrong just got there like Columbus did

Oh, I shouldn't have had seconds.

Literally, works even better with Plutonium.

Drinking a gallon of bleach will be enough liquid for the rest of your life. It will be an absolutely painful way to spend it though.

This just gives me spec-evo ideas for a person who does the shin-godzilla schtick where they ingest radioactive material and then use their inner fluids, either blood or some secondary circulatory system, as a coolant for the internal bio-reactor digestive system.

Either developing sail-hawks and sail-backs to expose as much surface area as possible, or Kit-Fisto style tail-locks with the same purpose.

Maybe a mix of both with the sail fans migrating to be like bat wings for that extra surface area cooling combined with high altitude chill.

Surprisingly I'd actually imagine this creature getting smaller, more use out of every bit of material they can find, and smaller creatures radiate heat more quickly than larger ones, so even more bio-coolant features to keep the reactor from making biological corium.

I think a gram of uranium will be able to pass through your digestive system without killing you. I wouldn't call it safe but that ammount of radiation isn't lethal. I don't know if it'd be poison, though.
