Simultaneous Separation of Actinium and Radium Isotopes from a Proton Irradiated Thorium Matrix
Abstract A new method has been developed for the isolation of 223,224,225Ra, in high yield and purity, from a proton irradiated 232Th matrix. Herein we report an all-aqueous process using multiple solid-supported adsorption steps including a citrate chelation method developed to remove >99.9% of...
