Abstract

A method of accumulating radium radionuclides, comprising providing a first solution including thorium radionuclides and a thorium-binding extractant, wherein the first solution does not bind to radium, allowing a portion of the thorium radionuclides in the first solution to decay into radium atoms and collecting radium atoms resulting from the decay. The collected radium atoms may be included in a solution in which brachytherapy sources are dipped, in a manner which collects the radium atoms onto the source.
