Modern methods for research on dynamics of radionuclides migration in the soil

Dynamics of radionuclides migration and distribution in the soil can be described with the use of additional experimental data and modern mathematical models. Migration in the soil is considered as diffusion process. Radionuclides migration velocity depends on soil type and its texture. The velocity may be higher (superdiffusion processes) or lower (subdiffusion processes) than the velocity fitted with Gaussian distribution. To analyze the problem fractal geometric approaches are applicable. The study is important for building modern models allowing investigation of radionuclides behavior in geological structures in order to ensure radiation safety of living organisms.
