Back in 1979 I used to work for some toilet of a company that made boxes to convert video to hard copy on Xray film. Customers were hospitals and clinics that had CAT scanners, and they were used to using Xray film for image storage, so our box had a video monitor inside, and a lens and Xray film holder to expose. The monitors were ones intended for security camera work, or pay extra and get our box with a Conrac monitor. The QQA was multisync (long before VGA!), and used those HV modules. We swapped the CRT for a smaller but flat 5 incher. We considered using different HV modules, but the chief engineer said the excessive HV will just make for sharper spot size, and as it's inside our box, Xrays from the CRT was not an issue. Not enough to fog the film after going thru the lens it seems.

The boss there turned out to be the 2nd worst manager of my life, knocked from 1st place by some idiot boss I had at Bell Labs.
