The purpose of the Liquid Scintillation Counting Working Group is to provide a forum for ICRM members to address issues related to liquid scintillation and Čerenkov counting. In particular, the CIEMAT/NIST efficiency tracing and the Triple-to-Double-Coincidence Ratio (TDCR) methods play major roles in Radionuclide Metrology. In the past two decades, many new developments were presented by ICRM researchers, e.g., new counter systems, new electronics for signal treatment and data acquisitions, investigations of existing models and extensions of calculation procedures. These methods are used for activity standardization of a growing number of radionuclides as well as for determination and validation of radionuclide decay data.
