My memory (which might very well be wrong) was that one of
the principal sources of X-rays was the HV rectifier. GE got into
trouble over excessive X-radiation from their HV rectifier -- though
the tube was situated such that the kids would have had to stick
their feet under the set (!!!) to receive any significant dosage.

Specifically, it was a GE-made 6BK4 that caused the problem,
so it ended up in all brands of sets via repair.

I vaguely remember that it was all alpha radiation, but don't take
my word as gospel.

Alpha rays are helium nuclei. Not likely, and not particularly dangerous.
