Radium-223 dichloride (radium-223) is a radioactive isotope that emits low levels of alpha particle radiation.
The alpha particle radiation causes double-strand breaks in DNA, killing cells.
Radium is not necessary for living organisms, and adverse health effects are likely when it is incorporated into biochemical processes because of its radioactivity and chemical reactivity.
When radium decays, ionizing radiation is a product, which can excite fluorescent chemicals and cause radioluminescence.
Radium, in the form of radium chloride, was discovered by Marie and Pierre Curie in 1898.
