Here, features of the radionuclide activity distribution in components of the limnetic ecosystems of the central Baraba lowland were studied, and factors affecting radiocesium absence in the bottom sediment of Lake Sarbalyk were identified.

Subsequent laboratory investigation involved the determination of major and trace element concentrations by atomic absorption spectrometry and X-ray fluorescence analysis; mineral composition by X-ray diffractometry (XRD); analysis of sample morphology and composition via scanning electron microscopy; and natural radionuclide and radiocesium content determination by the gamma-spectrometric method. Radiocesium is present in all the studied lake bottom sediments of the central Baraba lowland in the upper horizons, with the exception of Lake Sarbalyk. Limnetic ecosystem components were analyzed using modern analytical methods, considering the distribution features of natural and artificial radionuclides in catchment area soils, tussocks and the bottom sediment of Lake Sarbalyk.
