Skipping to very end: "In any case, it is a perfectly simple matter to view the cathode ray screen through a small sheet of lead glass. Since lead glass can stop the penetrating radiation from a powerful X-ray tube the use of such a simple precaution should clear away any possibility of danger from soft easily absorbed rays from the cathode tube - even assuming that such rays existed." The TVs we all grew up with operated at, if I recall correctly, 17kV, not just 400-800V like this thing. And we had our "lead glass", at least by the '70s.
