The Canadian National Calibration Reference Center for Bioassay and in Vivo Monitoring: an update.

The Canadian National Calibration Reference Center (NCRC) for Bioassay and In Vivo Monitoring is part of the Radiation Protection Bureau, Health Canada. The NCRC operates three performance testing programs that are designed to confirm that workplace monitoring results are accurate and provide the necessary external verification that is part of a comprehensive quality assurance program. The NCRC performance testing programs cover the in vitro, in vivo, and internal dosimetry parts of Canadian facilities' radiation protection programs. The internal dosimetry performance testing is a new addition to the performance testing suite. This summary also describes the recent reorganization of the NCRC.
