The Canadian National Calibration Reference Centre for In-Vivo Monitoring: thyroid monitoring. Part I: The national inter-comparison programme.
This article is the first part of a five-part series covering various aspects of occupational thyroid monitoring. The Canadian National Calibration Reference Centre for In-Vivo Monitoring conducts a thyroid inter-comparison programme that now includes more than 100 facilities. The scope of the programme, begun in 1988, has greatly expanded in the last two years following a considerable effort to locate and inform facilities. This article presents the details of the programme, its results, and the lessons learned. Subsequent articles will discuss sources of errors, methodology, instrumental configuration, and counting geometry optimization.
