WebRadium-223 (223 Ra, Ra-223) is an isotope of radium with an 11.4-day half-life.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 … Web2. Radionuclide Properties and Production of 225 Ac and Its Daughter 213 Bi 2.1. Decay Properties of 225 Ac and 213 Bi. 225 Ac is the parent radionuclide of 213 Bi and is a relatively long-lived α-emitter with a half-life of 9.9 d. It decays via a cascade of six short-lived radionuclide daughters to stable 209 Bi with four net alpha particles emitted per …
