225Ra/225Ac radiochemical separation method used for purification of ISOL-produced 225Ac. The solution resulting from etching 225Ra and 225Ac from the aluminum target was diluted with nitric acid (to 4 M HNO3) and loaded onto a preconditioned DGA resin (Horwitz et al. 2005). After washing the resin (with 4 M HNO3) to remove residual 225RaII, the 225AcIII was eluted from the resin 0.5 mL of 0.05 M HNO3
