This is bad but cavity water radiation is usually very weak. Ingestion could be bad but its not like he swallowed a uranium isotope which would be catastrophic.

FYI:

  the primary hazard from acute, high-dose uranium ingestion is chemical toxicity leading to acute kidney failure (nephrotoxicity), not radiation.

Fuck me, is there anything fun that isn't nephrotoxic?

[mlindner]

I wouldn't even call it bad. Reactor pools have basically zero radiation at the surface. The water is constantly filtered and kept very pure to remove contaminants that can be activated by neutrons.

Even drinking it I would think would be completely fine. The water itself doesn't get activated.

Then where did their radioactive hair come from?

[jojobas]

Water itself is activated by neutrons, even if slightly.

Is it not Heavy Water?

[yread]

Sounds like it was a lot more serious for the water than for the worker

The Uranium Isotopes would also not be that terrible. It's the fission products that get you.
