glass of the tube excite minerals on the surface.

Cerenkov radiation is a very different thing, happening only with
particles that are travelling close to the speed of light.

Yes, if you see REAL Cerenkov radiation, RUN!!! I've viewed it through
about 40 feet of water in a pool reactor. If there isn't a hell of a lot of
some kind of shielding between you and the glow, you're in trouble.
