Abstract
A statistical analysis of the measurements of the reference sources used for the calibration of the devices was performed in order to determine calibration factors for the used devices. High quality data sets are selected which can be used for the thyroid dose assessment of people not being monitored and for the derivation of correction factors for low quality measurements. The uncertainties due to the variability of the age-dependent thyroid mass, the thickness of the overlying tissue, and the position of the detector relative to the thyroid have been quantified. A neck-thyroid phantom is used to determine the dependence of the measured activity from these parameters. The real variability of thyroid masses and of the thickness of the overlying tissues is estimated for the population of Kiev. The results give quantitative information about the influence of those parameters on the reliability of the activity measurements. (orig.)
