Radium

A radioactive decay product of uranium often found in uranium ore. It has several radioactive isotopes. Radium-226 decays to radon-222.

radium

(Ra) Type: Term Pronunciation: rā′dē-ŭm Definitions: 1. A metallic element, atomic no. 88, extracted in very minute quantities from pitchblende; 226Ra, its longest-lived isotope, is produced as an intermediate in the uranium series by the emission of an α particle from thorium-230 (ionium); 226Ra emits α partic...

Radium

Radium consists of 16 isotopes, the most abundant being the Radioactive Radium-226. This is a metallic substance, has a Half-Life of 1602 years and Decays via a complicated chain, eventually leading to stable Lead-206. Along the way it decays to Radon Gas (Rn-222). Radium was isolated from pitchblende in 1898 by Marie and Pierre Curie. The activity...
