Uh...this isn’t about a “nuke plant”.
This is about particulate from the clean up of the waste storage.
Where did you get the idea “Nuke plant said all radiation contained.”???
These are trace amounts.
If you’re worried about these levels you’d better stay out of the sun.
Where there is nuke fuel, there is a history of nuke plant involvement. But yes, I could drop it in this case because it is the incompetent storage of said nuke fuel. As I skimmed web articles, “authorities” claimed all radiation was contained but obviously it wasn’t.
Of course you know that the gamma radiation from the sun does cause skin cancer but it entirely unrelated to particles of refined nuclear fuel blowing around - there’s no comparison (unless you unwittingly ingest part of the sun).
