Standardization of 18F by digital coincidence counting

The radioactivity of 18F has been measured by a digital coincidence counting (DCC) system. The main advantages of the digital coincidence counting technique are a shortening of the measurement time as compared with conventional coincidence counting and an ability to obtain activities with various experimental parameters through off-line analysis. The measurement results of radioactivity for 18F solution were compared with those of a conventional coincidence counting technique and a reference ion chamber method.

► Radioactivity of F-18 is measured by a DCC technique.
► DCC technique has an advantage for the radionuclide with short half-life.
► Activity results show a good agreement with those of other methods.
