I'm not sure how this thread wandered off the subject of EMF
radiation to X-rays - I guess the fear is, it all Hertz.

The amount of X radiation from a CRT is a function of high
voltage potential, shielding, and brightness.  A Tek storage
tube (4014, etc.) uses hundreds of volts for the stored image,
not enough to produce X-rays.  Small CRTs, especially monochrome,
use a low enough HV that few X-rays are produced.

Large screen and projection televisions can produce enough
radiation to pick up on a Geiger counter.  Not enough to
sterilize potato salad, but don't let un-fixed cats sleep on it.
