Thats weird. Radium is still active but didnt know it could give this effect.

Some of the daughter products in the decay chain from Radium can kick out high energy particles. You can get a sense of the particle type, by the trail it will leave in a cloud chamber. Especially for the high-energy cosmic rays that will zip through.

All I know is based on hard work & writing by others. I can only aspire to augment this body of knowledge. If I am wrong it is because of my own failings. -me
