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.

Keywords: 90Sr, barrier resistance, factors of contamination, water subtraction, watersheds
