By the example of the Chernobyl exclusion zone, using GIS and statistical methods, the crucial role of natural and man-made features of the landscape in the formation of a radiactive secondary contamination of the surface water, the volume of radionuclides (90Sr) carried out by water, and the barrier resistance of watersheds is proved. A methodology for assessing the barrier stability and modeling the scenarios of its strengthening to minimize the entrainment of radionuclides by water outside of exclusion zones is presented.

Keywords90Sr, barrier resistance, factors of contamination, water subtraction, watersheds
