The present work analyses the problem of radiocesium contamination of water bodies. The main object of research is the dynamics of radiocesium in water and bottom sediments of three Lithuanian lakes: Tapeliai, Juodis and Lydekinis. Lake Tapeliai basin is of the glacier origin and has bottom sources. Lake Juodis is a running shallow lake with a thick layer of bottom sediments (over 7 m). Lake Lydekinis is a small humic lake with highly colored water. Sediments and water samples were analyzed for 137Cs using a γ-spectrometric system. Investigation results deepen our knowledge on the processes of lake self-cleaning from anthropogenic pollutants and allow predicting the terms of super warm lake remediation after radioactive impacts. Estimating radioecological consequences of the radioactive impact to the natural water bodies, meromictic lakes are suggested as critical objects.
