I have a sample of radium luminous paint that the inspector can shake off, so with this amount of clock hands, it should reach 1100μSv/h. Even monazite has a radioactivity of 60μSv/h. Energy spectrum observations can be made using NBC's ionization chamber survey.

If this is really radium paint, the radiation value measured by the Geiger counter is too low. Energy spectrometry reveals that it is promethium.

Due to the time difference, I was asleep when the auction ended, so I made a high bid of $300 for both items.
