Wow, people are really clueless about how nuclear power plants really work. It's really not that dangerous to fall into the water.

Hey, no need to be condescending. Some people just haven't read [the xkcd.](https://what-if.xkcd.com/29/)
This is such a better response than "wow some people really are stoopid"
To be fair, you don’t have to be stupid to be clueless. We’re all clueless about plenty of things.
I mean, if you actually think there's a pool of "lava" that's dangerously radioactive at the surface, while people are walking right next to it, you might be a bit "stoopid". The whole reason water is used is that it shields from radioactivity pretty well
Why would the average person know this about the water used in nuclear reactors?

There are also plenty of jobs where people are in close proximity to insanely hot/dangerous liquids.

That's exactly my point, people are clueless about the basics of nuclear power. Why would they know it? I mean, why would the average person know what a linear equation is or what year the first world war started?
I found the "Nuclear Engineer reacts to XKCD" version of this video pretty interesting, too. Adds a little more context.

Life vest suddenly seems very relevant.
Just make sure the life vest is made of kevlar.
Or you have an employee badge.
I feel like you’re citing the primary source material for the vast majority of us. Like, “let me find the thing that original taught me how to think about radiation pools. Ah yes, this xkcd. Yep, here’s the manual.”
Can you please make your substantive points without putting others down?

No :)
The zeitgeist has been anti-nuclear for so many decades, fear pops up around any topic that's at all adjacent to a reactor.
Or maybe people just don’t that water mitigates radiation really well? You can be very pro-nuclear and still be concerned about radioactive contamination if you don’t know that radioactivity is dramatically reduced by just a few feet of water.
If you’re in the water, you may get a few feet less of that protection. Particularly if you swim down.
According to Randall Munroe, you'd actually experience less radiation about a metre under the water in a spent fuel pool then you do walking down the street.

On a tangent, I kinda love the fact that I've learned more about nuclear physics, orbital mechanics, and relativistic speeds from a poorly drawn webcomic than I have from any other source. (Ok KSP might actually have xkcd beat on orbital mechanics)

Why not both? Kerbal Space Program is XKCD approved:

It made me very sad when he stopped regularly writing those.
A lot of us grew up in the time of 3 Mile Island and Chernobyl. Combined with a lot of media about radioactivity's dangers (https://www.nytimes.com/1999/06/06/nyregion/babies-teeth-and...). I think that has strongly affected people's perception of risk.

I used to work at UC Berkeley, and one of the buildings on campus previously held a research nuclear reactor (https://en.wikipedia.org/wiki/Berkeley_Research_Reactor). There's a sign there now "Nuclear Free Zone"; (https://www.dailycal.org/archives/the-berkeley-nuclear-free-...).

Note that they did have to do extensive decontamination on Gilman Hall (https://en.wikipedia.org/wiki/Formerly_Utilized_Sites_Remedi...) where plutonium was first isolated.

I think for the general population we also have The Simpsons to blame. Ask anyone on the street what "nuclear waste" actually is and I'd wager at least half would say "a barrel with glowing green goo leaking out of it."
Which is funny, because everybody knows that's toxic waste (see Toxic Avenger from the 1980s).
You know the article that people love around around here, ‘Reality Has A Surprising Amount of Detail’… well it does, and most people don’t realize how little of it they’re even aware of.
As a person who knows way too much about way too many things. I am fully aware of this myself, however, the headline was shifted in a way that makes you perceive there's a problem caused by said person falling into water. So yes, logic tells you no problem but haven't recognition tells you they're trying to announce a problem. At the same time there was no problem.
Doesn’t it depend on how far they sink? I’m pretty sure xkcd did a comic on this. Oh, it’s a video, here it is: https://www.youtube.com/watch?v=EFRUL7vKdU8

Edit: ok, I’m probably the fiftieth person to point this out. It’s still a good video.

Few fun riffs for a Sunday morning:

Wow, people are really clueless about how nuclear power plants really work. They literally wrote up a safety report and transported them off-site.

Wow, people are really clueless about how to avoid reacting angrily. It's funny to append "they were wearing a life vest" to "they had a nuclear safety accident"

What, "morning", how dare you! It's late afternoon shading towards early evening here!

(Am I doing it right yet?)

It's literally 11:59 AM, Hieronymus. People don't get how time works. I'm the observer of spacetime!
Most likely including OP
Might be. If the reactor was recently defueled, especially, might there be more junk floating in the water?

If said junk was alpha- or beta-emitting, it could be enough of a danger for cancer.

It almost sounds plausible but it's not. All fuel is extremely heavy elements that in still water falls down and deposits on the bottom.
The fuel is (almost) harmless, it's the fission products that make reactors dangerous. Many of those are water-soluble. Of course the fuel elements should be encased, but drinking pool water is probably not a great idea anyway.
Probably is if you don't have a life vest.
Did you read the report? Doesn't sound like it was safe for him.
