Objective: to evaluate the maximum possible concentrations of radionuclides in the breathing area and the expected inhaled doses of irradiation of rural residents in case when timber harvested in the area of radioactive contamination is used as fuel. Material and methods: The data of the Institute of Radiology on the contamination of the area with radionuclides were used. Mathematical modeling was applied during the study. Results. The expected annual irradiation doses of the population of settlements situated by the border of the Polessky State Radiation Ecological Reserve due to the inhalation of 90Sr and 137Cs with furnace smoke can reach up to 0.27 mSv. The main contribution (96 %) of the expected radiation dose of the population due to stove smoke is made by 90Sr (in the absence of trans-uranium elements). Conclusion. The expected annual irradiation dose from the inhalation way of radionuclide release with the fly-ash from furnace smokes is much higher than from fires in the Chernobyl exclusion zone. The absolute values of the doses from this irradiation way do not exceed the legally established exposure limit (1 mSv per year) and are comparable with the external doses from the Chernobyl fallout.
