Actinium-227 and actinium-228 are the only naturally occurring isotopes. About. Due to this similarity the separation of actinium from lanthanum and the other rare earth elements, which are also present in uranium ores was difficult. The actinium series, known also as the actinium cascade, is one of three classical radioactive series beginning with naturally occurring uranium-235.This radioactive decay chain consists of unstable heavy atomic nuclei that decay through a sequence of alpha and beta decays until a stable nucleus is achieved. Uses of Actinium. It is used in thermoelectric power sources and also used in neutron emitters.

Practically actinium has not applications outside of research laboratories. Thorium is a moderately soft, paramagnetic, bright silvery radioactive actinide metal.In the periodic table, it lies to the right of actinium, to the left of protactinium, and below cerium.Pure thorium is very ductile and, as normal for metals, can be cold-rolled, swaged, and drawn. For decades, one place in the world has produced the majority of actinium-225: DOE's Oak Ridge National Laboratory (ORNL). This might drive the stock higher in the near term. ; Actinium was discovered in 1899 by French chemist Andre Debierne, who suggested the name for the element. Actinium is used either alone or with other medicines to treat partial seizures. Role in Life Processes It is an actinide, which also makes it a member of the rare earth element group, which is itself a subset of the transition metals group. It has, however, great potential because it has almost as low a density as aluminium and a much higher melting point. Actinium can also be artificially produced.
