When I was a young kid, there was a radioactive ring that you could order for a dollar or so. Under the bed with the lights out, you pulled off a cap
of a little tube on the ring, and if you peered inside, you could maybe see little flashes of light.
The rings were eventually removed from the market. I suspect the flashes of light was elements of the material (electrons) spinning off the main
material and impacting upon the optic nerve.
