Peculiarities of forming radioactive contamination of higher aquatic plants from Kyiv reservoir

Abstract

Peculiarities of forming radioactive contamination of higher aquatic plants from Kyiv reservoir in 2010 was studied. For the first time the levels of content 137Cs and 90Sr in plants from different parts of reservoir was ana-lyzed. Content of 137Cs in plants was registered on the level from 5 to 588 Bq/kg, 90Sr – from 0,5 to 50 Bq/kg. Levels of radioactive contamination of higher aquatic plants depended on peculiarities of radionuclides migra-tion in water area of the reservoir with water masses.
