Abstract
The accumulation of unwanted long-lived radionuclides during the production of 18F-based radiopharmaceuticals using the IBA Cyclone 18/9 HC cyclotron is considered. Using high-resolution gamma-ray spectrometry with HPGe detectors, the identification of radionuclides and the assessment of activity in activated components (stripper, target entrance window) of the "medical" 18-MeV cyclotron IBA Cyclone 18/9 were carried out. More than 20 unwanted radionuclides have been identified in irradiated water. Various mechanisms for the entry of longlived radionuclides into irradiated water are described. The results obtained are of great importance for optimizing the methods of radioactive waste management in the production of radiopharmaceuticals and, as a result, minimizing the radiation exposure of personnel.
