SINOPSIS

137Cs specific activity in higher aquatic plants and fish in water bodies differing in their types and trophic status and located within the territory of Ukraine was investigated in 2012-2017. In plants occurring in water bodies located within the Chernobyl exclusion zone, 137Cs specific activity accounted for 69,000 Bq/kg of plant air-dry mass, in fish it was 30,000 Bq/kg of natural humidity. In higher aquatic plants and fish found in water bodies located outside the Chernobyl exclusion zone, 137Cs specific activity accounted for 10,000 and 1,000 Bq/kg, respectively. In the above-ground organs of Phragmites australis and Topha angustifolia, the content of 137Cs was closely similar to that in their rhizomes, whereas in the soil roots it was almost 10 times higher than that in the above-ground organs and rhizomes.
The degree of 137Cs accumulation by higher aquatic plants and fish depends not only on the density of radionuclide contamination of catchment area, but also on the rate of water exchange and trophic status of a water body.
Outside the Chernobyl exclusion zone, the content of 137Cs in fish of the closed lakes located in the northern part of the Rovno and Kiev regions was higher than its limiting permissible concentration.
