Results of the study of 90Sr and 137Cs migration mobility in soils characterized with contrasting physical-chemical properties and granulometric composition has been analyzed. The mentioned radionuclides were introduced in soils in initial water-soluble form. Ecological and effective half-time of cleaning of soils 20-cm horizons (Tecol) has been estimated. Mean values of Tecol of 90Sr varies in range 3.7 - 84 years. Tecol of 137Cs varies in range 61 - 265 years. Correlation of ecological half-time cleaning of soddy-podsolic soils species from radionuclide and physical-chemical properties and granulometric composition of these ones has been analyzed, strong correlation of Tecol of 90Sr as well, as mean correlation of Tecol of 137Cs with mentioned soils characteristics has been noted.
