 INTRODUCTION

The radioactive environmental contamination caused by accident on the Chernobyl atomic power station stimulated studying a problem of radiating protection of biota (Aleksaxin R.A., Fesenko S.V., 2004), that needs calculations of dozes of an irradiation of objects of wildlife, research of radiating effects and definition of a "doze - effect" relationship. For deriving prognostic and retrospective assessments of exposure doses of a biota for long period it is necessary to know change in due course parameters of models of transfer of radioactive nuclides in components of an environment. Special interest is represented with performances of vertical migration of radionuclides in the upper root layer of not cultivated soils which plays the important role in composition of radiation doses on a biota. In this connection, dynamics of parameters of compartment model (KM), widely applicable for description of transfer of radioactive nuclides in an environment, was investigated
