> You may actually receive a lower dose of radiation treading water in a spent fuel pool than walking around on the street.

Wow

Is it relevant? It's writing about a pool for storing spent fuel, which is not a part of the actual reactor system.

  This incident report says that the worker fell into a "reactor cavity" containing water and that there was a measurable amount of radiation detected in their hair after the initial clean-up. The two situations don't seem remotely compatible to me.

I guarantee you there's 'a measurable amount of radiation' in your hair right now. Unless you're bald, I suppose.

So if I understand this correctly (solely from reading the xkcd), then the person might actually be okay?

They're totally fine.

I find it highly informative that the required PPE for working in that location is a life jacket so you float in case you fall in, rather than a tether and fall arrest harness so that it's not possible to fall in.

300 CPM is nothing, background levels might be 150.

> Plant officials today confirmed the worker sustained minor injuries from the fall and has already returned to work. - https://www.mlive.com/news/2025/10/michigan-nuclear-plant-wo...

He went back to work the next day. They don't provide much detail about the minor injuries but it seems that the biggest issue is maybe a bruised shin from the fall.
