This. Sitting several feet away with the radium behind glass, you're down near background [1], but any contact with the dust is a risk. If you must to open the case, I would suggest doing it outside with mask, gloves, and eye pro: blow the case out with some compressed air to dispel any lose dust. Don't grind or disturb the markings otherwise. You can also replace the hands with non-luminous ones. Also consider leaning in! Radioactive antiques and minerals is a whole fun hobby by itself; start with a cheap Geiger counter and move up to a scintillator for more fun. There are many artifacts like uranium glass, ceramic glazes, and watches to look for in antique shops. https://www.kensclockclinic.com/vintage-clocks-and-radium-risks/ https://www.kensclockclinic.com/vintage-clocks-and-radium-ri...
