Radium-223: Applications, Art, Standards & Products

Radium-223 (223Ra, Ra-223) is an alpha-emitting isotope of radium with half-life 11.435 days. It 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…
