The Canadian National Calibration Reference Centre for In-Vivo Monitoring: thyroid monitoring. Part V: Minimizing placement error in a thyroid monitoring system.
This article is the last of a five-part series covering various aspects of occupational thyroid monitoring. This part describes the techniques for minimizing errors due to improper placement of the detector. The impact of counting time and minimum detectable activity as a function of detector position are also discussed. The importance of minimum detectable activity is exemplified by showing how it can be used to ensure that the thyroid monitoring system can detect an amount of radioactivity below the derived investigation level.
