Abstract  

A solvent extraction system has been developed for the separation of172Lu from its long-lived172Hf parent. The parent-daughter pair in equilibrium is maintained in a solution of HDEHP, and the heavy lanthanide daughter is extracted into 9M HCl. The separation factor for this generator is approximately 104. The rare-earth activity so obtained is proposed for compound labelling research and animal biodistribution studies in nuclear medicine.

Abstract  

82Sr has now been produced by the spallation of Molybdenum by protons of up to 800 MeV. The radiochemical recovery of strontium is described together with a description of the analytical techniques used to estimate recovered yields of the various radionuclides generated. A radionuclide generator is described for the rapid recovery of82Rb, the 1.25 min half-life decay product of82Sr. An outline is given of the quality control procedure adopted to ensure that the82Rb is suitable for clinical use.
