Results of the radioactive contamination of Kanev reservoir ecosystem studies were presented. Data of 90Sr and 137Cs content in abiotic and biotic components were analysed. 137Cs content in aquatic plant depending on space of contact of this hydrobionts with water were analysed. In 2000 137Cs сontent in fish of Kanev reservoir exceeded by 11 times the contents before the Сhornobyl accident.
Zarubin et al. (Sun,) studied this question.
