Title: System and method for collecting and isolating radiosotopes

Abstract

A method for obtaining 225AC from 225Ra having the steps of assembling a column having an inorganic stationary phase; priming the column to immobilize 226Ra 225Ra and natural decay products therefrom; immobilizing the 226Ra, 225Ra, 224Ra, and natural decay products therefrom onto a stationary phase within the column; and eluting the column containing the 225Ra with an aqueous sulfate solution to obtain a milking effluent that contains 225AC. Also provided is a method for obtaining pure 225AC from its isotope parents, the method comprising assembling a column having a stationary phase comprising an inorganic material; priming the column with the isotope parents to immobilize 225Ac, and natural decay products of 225AC; immobilizing the 225Ac, and natural decay products therefrom onto the stationary phase within the column 226Ra, 225Ra, 224Ra; and eluting the column containing the 225AC to obtain an effluent that contains the isotope parents.
