           | So far, it seems that hasn't materialized - not, I suspect

             | Only the oldest CRTs used leaded glass for the front,
             | because leaded glass gradually turns brown on exposure to
             | X-rays. More modern CRTs used glass with barium and
             | strontium for X-ray shielding in the front. They still used
             | leaded glass for the back and sides, presumably as a cost
             | saving. I don't see any reason why you couldn't use the
             | barium-strontium glass for the whole thing. Alternatively,
             | CRTs could be made with ceramic bodies like Tektronix used
             | to do.
             | 
             | The energy of the X-rays produced is limited by the CRT's
             | acceleration voltage. The electrons get almost all of their
             | energy from the field produced by the acceleration voltage.
             | Electrons can produce photons when they hit matter, and one
             | electron produces at most one photon, so by conservation of
             | energy the X-ray cannot have greater energy. Smaller CRTs
             | typically use low acceleration voltages, which means the
             | X-rays are low energy and thus easy to block.

       | 
       | It turned out that they wanted it for themselves, and didn't that

       | wouldn't be brought)?
       | 
       | Fortunately the gamble worked out, and the TV wasn't destroyed.
       | 
       | There's also a possibly related matter, in how Sony stopped

       | government aren't very happy to learn that a possibly unique
       | museum piece, of one of the heights of Sony achievement, was
       | quietly removed from the country, to the US, by a YouTube
       | influencer?
       |
