(57) Abstract :
The present invention describes a method for purification of 225Ac from irradiated 226Ra-targets provided on a support, comprising a
leaching treatment of the 226Ra-targets for leaching essentially the entirety of 225Ac and 226Ra with nitric or hydrochloric acid,
followed by a first extraction chromatography for separating 225Ac from 226Ra and other Ra-isotops and a second extraction
chromatography for separating 225Ac from 210Po and 210Pb. The finally purified 225Ac can be used to prepare compositions useful
for pharmaceutical purposes.
