radium
Decaying alkaline earth
Radium is a radioactive metallic element, discovered by Marie and Pierre Curie in 1898.
Once used in luminous watch dials and quack medical treatments, its dangers became apparent as workers developed radiation poisoning.
The element glows faintly blue-green and decays into radon gas.
Its name comes from the Latin word for ray.
