Who discovered radium and when?
Radium was discovered in 1889 by French chemesists Marie
Sktowska-Curie and her husband. Some common uses for radium is in
self luminous paints, "glow in the dark" lights in most watches,
and medical use. It is not very safe for medical use and is
therefore used mostly by quacks because of extremely dangerously
high level of radiation.
