Article: Credibility of Chernobyl thyroid doses exceeding 10 Gy based on in-vivo measurements of 131I in Belarus.[show abstract] [hide abstract]
ABSTRACT: Many estimates of individual thyroid doses to children and adults in Belarus have been based on the results of direct thyroid measurements made using survey meters soon after the Chernobyl accident in 1986. Thyroid doses from internal exposure to 131I that are estimated using such measurements are usually considered to be better than estimates obtained by environmental transport modeling of concentrations expected in milk. Nonetheless, some of the estimated doses, primarily those to children, were high enough to raise questions about their credibility. Questions about high thyroid doses, taken here to be those exceeding 10 Gy, identified the need for further analysis, which is reported in this article. The overall conclusion is that the initial dose estimates exceeding 10 Gy based on direct thyroid measurements in Belarus are credible estimates and not mistakes. While the possibility of copying and data entry errors cannot be completely ruled out, the consistency of multiple measurements for many individuals supports the high dose estimates.Health Physics 03/2008; 94(2):180-7. · 1.68 Impact Factor

ABSTRACT: The main stages of the work conducted and the results of thyroid dose reconstruction for the Belarusian residents are presented in the paper. The problems relating to the systematic errors which occurred during in vivo monitoring of 131I-thyroid content are considered. The importance of using the most adequate model of thyroid dose formation has been justified in order to account for systematic errors. The main statements of the modified semiempirical model of thyroid dose formation have been described. The problem regarding possible production of fresh fission products (including short-lived radioiodines) at the time of the explosion of the Chernobyl reactor is presented. The main materials related to presentation of the results of our investigations on thyroid dose reconstruction in Belarus were in the literature, for example, , , and . This is the reason for which they are described here in a shortened view. The main attention is paid to the questions, which are actual for the time being, and those questions are likely to be actual in the future. Because of their importance those questions are being discussed in the framework of BelAm and UkrAm thyroid cohort projects as well as of the other projects.International Congress Series.
