title: Canadian national internal dosimetry performance testing programme: results of the pilot programme.
abstract: This paper describes the design and construction of a new performance testing programme that was implemented in Canada in 2008. The Canadian Regulator (Canadian Nuclear Safety Commission) had determined that their licensees, in addition to participating in the existing in vivo and in vitro performance tests, needed to demonstrate their ability in interpreting bioassay results to obtain intakes and resulting doses. The new programme is administered by the Canadian National Calibration Reference Center for Bioassay and In Vivo Monitoring (NCRC). Currently, the NCRC carries out the performance testing for the in vitro and in vivo. At the time of writing, the first round has been completed and the results for (3)H and (nat)U exposures were very consistent, while the committed effective dose from (137)Cs intake varied by a factor of two.
