Could I have been exposed to anything when the glass shattered inside
the set or when I powered the thing on with the glass shattered?


No.

Do they still use mercury to flash the getter in the CRT gun assembly? I'd
be a little worried about that possbility.

Do you have any technical info sources that show mercury was ever used in
getters?

I doubt it. Mercury is not that reactive. He's probably just thinking
of the shiny getter coating and associating it with mercury.

I got my vacuum technology mixed up. Mercury is used in some kinds of
vacuum pumps. Barium is the most used material for a vacuum tube getter.

Right. Older diffusion pumps used mercury. Newer ones use special low
vapor pressure oils. But both types are rather obsolete now.
