More info:
Actinium like most of the other Lanthanoid elements, is extremely rare in natural occurrence. It is produced mostly through nuclear reactions in the laboratory. Actinium forms a handful of compounds in the +III oxidation state. A major area of research involving Actinium involves using its high radioactivity in disease treatment. It is also used as a source of neutrons, and in modelling ocean water mixing.
