Prostate stimulation in 1920's

Causes or cures prostate cancer?

that cant be good. I'm sure alot of people died from using those things. I watched a documentary on netflix recently about the beginning study of toxicology. When radium first hit the market they put into everything before they realized people were dying from it.

We weren't very smart about radiation until after WWII.

The dangers continued into the early 1940's. Our family had an old alarm clock with luminescent dial markings. A sticker on the clock noted that the Radium markings were more durable than cheap imitations. Later I learned that women who painted the dials suffered tongue cancer, probably from licking their paintbrushes.

I remember having shoes fitted with a fluoroscope machine as late as 1946.

@rook, yeah the documentary I watched spoke specifically about all of the women who died from painting the lumiescent hands on watches. They were taught to lick the end of the paintbrush to form a tip for fine detail.
