The authors present their technique to describe characteristics of radionuclides migration in the topsoil. The developed method is based on the fractal analysis of spatial patterns. For the qualitative analysis Cs-137 and Sr-90 in the topsoil layer was measured. These radionuclides were selected for analysis due to their long half-life and the ability to be easily included in the food chain, that can cause internal or external exposure of the public to the radionuclides. Abnormal diffusion of the radionuclides detected with the use of the fractal analysis speaks on non-classical spatial distribution of the radionuclides. The technique allows improvement of radioenvironmental monitoring program.
