- Biological Role: Radium has no known biological role. It is toxic due to its radioactivity.
- Natural Abundance: Radium is present in all uranium ores, and could be extracted as a by-product of uranium refining. The usual source of pitchblende comes from Bohemia, but some radium-containing ores are found in Canada and the USA. Annual production of this element is less than 100 grams
