And just because it no longer glows, does NOT mean it's no longer radioactive. Radium half-lifes in 1600 years; the 'glow agents' deplete after a few years.
I dont know how dangerous these items are, though. Radium undergoes alpha particle decay, and those particles are easily stopped. Even a paper bag will block alpha particles. But if you were to ingest an alpha-particle emitter, that will be bad. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
