Radium is a solid metal that belongs to the group of the alkaline earth metals and has no stable isotopes. Naturally occurring radium is found in animals, plants, water, soils, and rock. It is mainly found in Phosphate rocks. While the element is present in uranium ores, it is a scarce one. There is only 0.14 grams in 1,000 kg of uranium.
Radium-223 (223 Ra, Ra-223) is an isotope of radium with an 11.4-day half-life was discovered in 1905 by T. Godlewski, a Polish chemist from Kraków, and was historically known as actinium X (AcX). Radium-223 dichloride is an alpha particle-emitting radiotherapy drug that mimics calcium and forms complexes with hydroxyapatite at areas of increased bone turnover.
