title: Standardization of 18F by digital coincidence counting.
abstract: The radioactivity of (18)F 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 (18)F solution were compared with those of a conventional coincidence counting technique and a reference ion chamber method.
