Thorium-223 is an alpha emitter
WebTraditionally, 225 Ac has been sourced from thorium/actinium generators based on the alpha decay of stockpiles of 229 Th. 229 Th is itself the alpha-decay product from 233 U. Due to proliferation issues associated with 233 U, only three thorium/actinium generators have been reported in the literature, capable of supporting clinical research.
