The discussion on X-Rays was interesting, but I think their confidence was slightly misplaced. I know that I sat much closer than 6 feet as a youth.
"It is, therefore, very doubtful whether any appreciable percentage of such rays would even get through the screen itself, let alone the glass wall of the cathode ray tube. In fact, very soft X-rays are absorbed by a few centimetres or even a few millimetres of air."

"Concerns about x-rays emitted by CRTs began in 1967 when it was found that TV sets made by General Electric were emitting "X-radiation in excess of desirable levels". It was later found that TV sets from all manufacturers were also emitting radiation. This caused television industry representatives to be brought before a U.S. congressional committee, which later proposed a federal radiation regulation bill, which became the 1968 Radiation Control for Health and Safety Act. It was recommended to TV set owners to always be at a distance of at least 6 feet from the screen of the TV set, and to avoid "prolonged exposure" at the sides, rear or underneath a TV set. It was discovered that most of the radiation was directed downwards. Owners were also told to not modify their set's internals to avoid exposure to radiation. Headlines about "radioactive" TV sets continued until the end of the 1960s. There once was a proposal by two New York congressmen that would have forced TV set manufacturers to "go into homes to test all of the nation's 15 million color sets and to install radiation devices in them". The FDA eventually began regulating radiation emissions from all electronic products in the US."
- Stratoscope 5y agoWhen I was a kid we sat literally inches from the screen. This was because of a TV show called Winky Dink and You: https://en.wikipedia.org/wiki/Winky_Dink_and_You https://en.wikipedia.org/wiki/Winky_Dink_and_You You would go to the store and buy a special kit with a vinyl sheet that stuck to the TV screen and special crayons you could use to write on that sheet and interact with the characters in the show. I think what saved us was parental wrath. All the kids in the neighborhood discovered that you didn't need the special vinyl sheet, and in fact you could use ordinary household crayons to write directly on the TV screen! And that was the end of Winky Dink.
