Radium is a highly radioactive alkaline earth metal discovered in uranium ores and historically used for luminous applications and medical therapies.
Properties of Radium | It behaves chemically like other group 2 metals, forms +2 cations and emits alpha, beta and gamma radiation depending on isotope.
Uses of Radium | Once used in luminous paints and cancer treatments, radiums use is now limited to specialized industrial and research roles due to radiological hazards.
Isotopes of Radium | Radium 226 is the most notable isotope with long half life and radiotoxicity; legacy contamination and waste require strict remediation and regulatory oversight.
