  • If these are hot, would you say my Fiesta Ware saucer at 45,000 to 48,000 CPM as measured by my Inspector Alert, is dangerous?

    It's in the garage, but i wonder if I should get a lead case for it. The Inspector Alert starts reacting from a couple feet away.

  • Fiestaware has no radium in it. I wouldn't eat from it, but it is relatively safe.

  • It looks like the radium paint is under a glass shell. The tip of the switch is covered by what appears to be a glass layer.

    Have you got any radium watch hands/needles? I do not, but have seen really old cardboard boxes of them on steal-bay.

  • @AtomicEmporium well i meant oxide anyways :P but true true

  • @Huffdev dioxide would be black :P It's trioxide.

  • @dahur it has uranium dioxide in the glaze

  • Awesome Second Video Too! I have those same switches, they must be the same manufacturer as mine, as I have 6 of them, and they all have the similar markings on them. The patent on mine say 1605910. I do have them in order like yours too, weakest to strongest, using just a small Ecotest Geiger counter, although these look like double function, mine are momentary, but they look identical. Maybe yours are older/newer than mine? I'm not sure... Thanks for these posts! 5/5! Incredible!

  • look for old non working radium watches. they will gave the old radium you want. just search "old watch" and that should get what you want! dont search old radium watch, will come up with WAAAAAAAAAY too expensive watches. look on "Steal-Bay"

  • Part2 is very impressive

    These little toggles are fun.

    Keep up the fine work.

  • The radium is under a glass shell. A similar design was incorporated into household light switches. Check US Patent 1749881.
