Using a High- Purity Germanium gamma-ray spectrometer, a number of radioisotopes have been identified within Tracerlab MX radiochemistry system cassettes used to synthesise [18F]FDG. Twenty radiochemistry cassettes were measured and the average total activity of each radioisotope was determined. Using these values and decay correction, the minimum time the cassettes should be left in a decay store before the specific activity falls below 0.4B q/g, the limit for disposal alongside Clinical Waste was found to be 24 months.
► Long-lived radionuclides are present in the single-use cassettes used for the synthesis of FDG. ► Disposal method of FDG cassettes need to be established. ► We investigated and determined the level of these long-lived radionuclides. ► Recommended storage time for FDG cassettes is 24 months to be disposed as clinical waste.
