Good luck with your quest. Radiological materials such as radium are very tightly controlled out of fear of someone gathering enough of them to manufacture a "dirty bomb."

All the world’s a stage, but obviously the play is unrehearsed and everybody is ad-libbing his lines. Maybe that’s why it’s hard to tell if we’re living in a tragedy or a farce.
Years ago I worked for a company that was licensed to use radium glow sheets. They were used for measurement of thin film metals. I wasn't sure of they are regulated but apparently they are as they don't come up as a standard consumer item. Unfortunately current restrictions make things difficult for experimenters and hobbyists. I was hoping to use a thin strip of radium glow sheet as a source for a true random number generator. I guess as an alternative a sample of Uranium Ore, a tiny chip of Americium, or a dial from an old radium clock, or a lab point source would work fine as a random number source.
I keep my 2 feet on the ground, and my head in the twilight zone.
