Excuse me, but you *DO* have a vacuum tube, and it most likely *does*
If you have a color TV, 19 inch or larger screen, then you got it!!
House-some-ever (or is that home-some-ever?), the leaded glass absorbs
most of the (soft) x-rays that are generated.
Now gamma radiation is such high energy, that you can only detect it
coming fom the cosmic sky (May GOD be praised, my Gramma illuminates
Jokes aside, what i said is correct.
