A mobile bio plateau design has been developed for water’s bodies purification from radionuclides. To construct bio plateau chemically inert floating material was used as the substrate granular foam on top of which the seeds of higher terrestrial plants were placed. Constructed bio plateau on the 9th day of incubation were placed into tanks with a solution of 137Cs to study the cleaning efficiency of terrestrial plants to the aquatic environment. Once a day, the solution of 137Cs was poured into Marinelli's vessel to determine the specific activity of the radionuclide using a gamma spectrometer. A comparative study of the cleaning efficiency of terrestrial plants of the aquatic environment on the example of 137Cs ions has been carried out. The results of mathematical modeling of the dynamics of accumulation of radioactive cesium in the “experimental reservoir – bio plateau” system was presented.
