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.
使用高纯锗γ射线光谱仪，在用于合成[18F]FDG的Tracerlab MX放射化学系统盒中鉴定出了多种放射性同位素。对20个放射化学盒进行了测量，并确定了每种放射性同位素的平均总活度。利用这些值和衰变校正，发现放射性比活度降至低于0.4Bq/g（与临床废物一起处置的限值）之前，这些盒应留在衰变储存库中的最短时间为24个月。
