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.
