Abstract

The authors present their technique to describe characteristics of radionuclides migration in the top-soil. The developed method is based on the fractal analysis of spatial patterns. For the qualitative analysis ¹³⁷Cs and ⁹⁰Sr 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 radionu-clides 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.

Key words
¹³⁷Cs, ⁹⁰Sr, soil, radioecological monitoring, fractal structures, fractal dimension, fractional integro-differentiation, sanitary protection zone, observation zone, JSC “SSC RIAR”.
