Radioactive quackery is a real pet topic of mine so mind the sperg.
In the 1910s-20s and even as late as the 60s there was a fad for radioactive health tonics and devices. You could buy bottled radium water or even a ceramic crock lined with radium ore to make your own at home. There were places that would charge you to sit for hours with your feet and hands or even your whole body touching uranium sand. There was a uranium card you put in your cigarette pack marketed as a way to reduce the chance of getting cancer. We put it in face cream and tooth paste to give you that nice healthy glow, wove it into pillow cases and made plaques from radioactive ores to put over your eyes while you slept, and sold it in pills and candies. And of course, there were radioactive suppositories and condoms to make your dick harder.

The fad started to decline when Eben Byers, an iron magnate, pro golfer, socialite, one of those rich eccentric types of the early 20th century, died from drinking the popular tonic Radiathor, a concentrated radioactive water that doctors were given generous incentives to push on their patients. By the time he stopped taking it in 1930 his jaw rotted off, his skull was rotting, his brain was abscessed, and he had several different kinds of cancer. When he finally kicked the bucket he had to be buried in a lead-lined coffin to prevent his corpse from contaminating the groundwater.
But fun fact: you can still buy some of this shit. There's still a real fad for it in Japan surrounding their hot springs bathing culture, and you can buy all kinds of mildly radioactive crap to bring home with you. Even in America some of the less "pop your spine back into place" more "my magic hands can heal your cancer" chiropractors will happily use all sorts of radioactive quackery to diagnose you with a thousand made up conditions.
There's a really readable book out recently called
Radium Girls all about the women who worked in watch factories where they used radium paint to make the numbers on the dial glow. They were told it was perfectly safe and used to lick the brushes to keep a point on them and paint their faces and teeth as a practical joke. Then all their bones started to rot and their jaws fell off. Good times.
