Isotopic generator for bismuth-212 and lead-212 from radium

Patent ·
OSTI ID:6508351

In an isotopic generator system, a method of using thorium-228 supply material disposed in a radiologically controlled portion of the system for producing radionuclides of bismuth-212 and lead-212 in a cation exchange resin bed, comprising the steps of: (a) separating radium-224 from a solution of thorium-228 supply material in an approximately 8 molar nitric acid in the radiologically contained portion by passing the solution through a strongly basic anion exchange resin; (b) transferring the radium-224 to the cation exchange resin bed from the radiologically contained portion; (c) producing the bismuth-212 and lead-212 radionuclides by decay of the Radium-224 in the cation-exchange resin bed; and (d) eluting the bismuth-212 and lead-212 from the cation exchange resin bed with th acid.
