Radioecological problems related to justification of the planned nuclear energy facilities and systems, as well as their "maintenance" during the operation process, are subjects to the analysis. The principles of "object monitoring” were formulated. They include the comprehensive evaluation of the integrated index – the radiation dose considering all pathways of radiation exposure and the optimal organisation of works combining both experimental and computational methods. The paper outlines the "stepwise approach" to radioecological monitoring of the nuclear fuel cycle enterprise. Prior assessment at the first stage (after the initial radioecological survey) allow planning the experimental work focused on conservative assessment of the total dose. On the basis of processed experimental data obtained in the observation zones of NPPs, the law of distribution of density of soil contamination with radionuclides was established. Dispersion values were determined. The results of a point conservative estimation and additional probabilistic analysis allow us to conclude, that to meet the requirements of radioecological protection and safety in the vicinity of nuclear facilities more detail and more cost-based research is necessary.
