The study shows the radiation situation on the territory of settlements located beside the impact zone of the nuclear power plant in Uzbekistan at the «zero stage», with definition of dominant species of flora and fauna; on the basis of which, the most suitable bioindicators for further research will be identified. Within frame of this work, the territories of fives settlements in the Republic of Kazakhstan, the nearest to the power plant site of top priority in Uzbekistan were examined. Radiochemical analysis, methods of radio spectrometry, mass spectrometry were used. The objects of study were soil, water, biota, food. In soil samples taken in Zhetysai and Zhyly-su, the specific activity of 232Th was twofold higher than the national average. The total alpha-activity of portable water samples in the village of Zhyly-su exceeded one-and-a-half fold of the allowable level. The concentrations of artificial (137Cs and 90Sr) as well as natural radionuclides (226Ra and 232Th) in the food products of population were within the standard. Dominant species of plants and animals for further use as the bioindicators of quality of environmental objects were proposed. The results obtained would enable to estimate forecasted effective doses for population and develop a monitoring system as well as a list of indicators for monitoring and evaluating the zero background of the selected territory. The monitoring model and its components used in this study may be applicable to other countries (in a transboundary context).
