• [F-18]FDG
• Medical cyclotron
• Radioactive by-products

Radioactivities produced in replacement parts and liquid wastes in a medical cyclotron used to produce F-18 for [F-18]FDG with 10 MeV protons were analyzed. Nineteen radionuclides were found in the replacement parts and liquid wastes. Among them, long-lived Co-56 in the Havar foils is critical in terms of radioactive waste management. The estimated dose level of exposure for the operating staff during the replacement of parts was around 310 mu Sv/y, which is smaller than the recommended dose limit for workers.
