What is radium nitride?

Pure radium is silvery-white, but it readily reacts with nitrogen (rather than oxygen) on exposure to air, forming a black surface layer of radium nitride (Ra3N2).

Why was radium used in toothpaste?

Development. The toothpaste was slightly radioactive because it contained small amounts of thorium obtained from monazite sands. Its radioactive content was promoted as imparting health benefits, including antibacterial action and a contribution to strengthening the “defenses of teeth and gums”.

What is pitchblende used for?
