Author: Kadiev, Aliphan Yusupovich

Reference: Obninsk, 2010

Keywords: Republic of Dagestan, population, internal radiation, external exposure

Abstract: The aim of the thesis; to estimate the annual and cumulative effective doses of the whole body dose of the population in the Republic of Dagestan on the basis of measurements of radioactive contamination of the soil, the dose rate in air and information about soil types and diets in various regions of the Republic.

DOI: http://dx.doi.org/10.1016/j.jenvrad.2009.08.005

Keywords: Chernobyl accident; Iodine-131; Environment modeling; Models validation; Population; Thyroid dose

Abstract: Within the project “Environmental Modelling for Radiation Safety” (EMRAS) organized by the IAEA in 2003 experimental data of ¹³¹I measurements following the Chernobyl accident in the Plavsk district of Tula region, Russia were used to validate the calculations of some radioecological transfer models. Nine models participated in the inter-comparison. Levels of ¹³⁷Cs soil contamination in all the settlements and ¹³¹I/¹³⁷Cs isotopic ratios in the depositions in some locations were used as the main input information. 370 measurements of ¹³¹I content in thyroid of townspeople and villagers, and 90 measurements of ¹³¹I concentration in milk were used for validation of the model predictions.A remarkable improvement in models performance comparing with previous inter-comparison exercise was demonstrated. Predictions of the various models were within a factor of three relative to the observations, discrepancies between the estimates of average doses to thyroid produced by most participant not exceeded a factor of ten.
