The attachment is of the last page of a rca 1956 tube manual print for the 21AXP22, and is of the x-ray radiation and the use of 1/4" safety glass, and they only mention x-ray protection.... While small, they do mention it. I'm sure once the words "x-ray radiation" made it into public knowledge some parts of the general public were nuts crazy and would not even go to a store that had a color tv in it.... My Mom would not have color tv for this reason, she even freaked out about the b&w sets, saying they had radiation too..... So for that reason, I'm sure rca at least partly used special safety glass to stop some of that deadly radiation.....
While this front glass would protect the more delicate tube from a direct hit, I think the bonded glass with the PVA was closer to safety auto glass with plastic between the two pieces of glass for strike protection, while the front glass could also have contained lead for radiation.....
I'm just wondering if there is any data to back up any of these ideas I had about the pva tubes...
