Radium was thought to be some sort of miracle cure. So they had baths thought to help cure people from diseases. But today it is used for cancer treatments because of its effects on people.
Radium Watch Hands
Radium glows in the dark as well, before it was known for its harmful effects, it was used as glowing watch hands and luminous paint.
I have a habit of playing with things, which is the reason I was unemployed, but I used to have a job in luminous paint and medicine. But I got caught playing around with people during work time. But because of that, that actually helped me find my new job dealing with cancer cells in bones. It's pretty cool.
