The used fuel bundles must remain under at least 6 feet of water or the whole refuel floor would start hearing their radiation badges beeping. The blue light only happens in water. In air you see nothing, I assume. By far away I mean in reactor which is like 60 or so feet underwater when the reactor cavity is flooded.

Your eyes would burn in radiation, but the static only occurs on cameras. I think high intensity particles can cause vision abnormalities, but I think our brain is good at hiding background noise pretty good. Filling in the gaps as it were. Or the mechanism of sight just isn't as affected as the electronics in camera sensors. Not sure on the physics of that.
