Description
During the routine operation of radioactive heavy-ion beam facilities, tremendous quantities of radioisotopes get deposited or produced at multiple sites throughout the accelerator parts and beamline components. This presents an opportunity to harvest the long-lived radioisotopes that have wide ranging applications once these components and parts are decommissioned and often, considerable activities will have built up by then. One such decommissioned component from the National Superconducting Cyclotron Laboratory (NSCL) was the tungsten beam-blocker that acted as the beam-dump for the primary heavy-ion beams while NSCL was in operation. This work elucidates the radioanalytical separation techniques and methodologies used in the extraction and purification of Hf-172 from the tungsten beam-blocker and the other co-embedded radionuclides such as Lu-173, Lu-172, Na-22, Co-56, Co-57, Co-58, Co-60 amongst others. The harvested Hf-172 was used for generating Lu-172 employing the use of an extraction chromatographic resin and radiolabeling studies were carried out with the generated Lu-172.
