This sounds like something that was made up for a fallout game.
Of course, so does "bombarding myself with xrays and moving around to entertain the audience looking at my bones" and "including uranium in paint to make watch dials glow"
Uranium wasn't used for watch dials, but Uranium Orange is a colour of cermic glaze. It was pretty popular in America from the 1930's to around 1942, when the government needed all the uranium for some big secret project. After the 60's it was made with depleted uranium, instead of natural ore, until someone realized this still wasn't a great idea.
I believed this was real until I searched for it 😂 To be fair to my own credulity, Plutonium Jazz would not be the most insane thing people did with radioactive materials back then. The "medicines" alone make Plutonium Jazz sound pretty tame.
