There is one easy way to find out. Shine a UV light on it. Florescence without retaining glow is a good sign of Radium. If no florescence than likely no lumed material.

I know this test to work for tritium-based lume, but have read it isn't applicable to radium. It does work to detect my cotton undershirts. Wink
