Estimation of the radiation burden of the inhab-itants is the reliable index of the residential area radioecological situation. In Krasnoyarsk region there is the Mining and chemical plant Federal state unitary enterprise, Federal nuclear organization. The plant ranges with the first category potential radiation hazard plants. The supervised zone, es-tablished for the plant, includes the territory of 20 km radius around the gas-aerosol emission and the Yenisei river floodplain 1000 km length. In the article the results of radioecological investigation of the agrarian landscape, territorially belonging to the Mining and chemical plant supervised zone were set forth. The aim of the work was the calculation of the Bolshoi Balchug village inhabitants radiation doze. The village is located within the supervised zone. This work was preceded by the work aimed at the determination of the specific activity of the soil, water and animal production, produced in the agrarian landscape. The doze calculation was made in accordance with the regulations and standards. Gamma-ray background doze estimation was based on the results of the pedestrian gamma radiation survey of the village territory, radon equivalent equilibrium volume activity in the air of the village dwellings, values of the technogenic radionuclides specific activity in the animal prod-ucts. As the result, it was found out that Bolshoi Вalchug inhabitants receive personal doze of inter-nal irradiation equal to 0. 26 mSv per year through the peroral route of radionuclides with food and drinking water. This number includes 0.16mSv per year of personal doze of internal irradiation received due to the technogenic radionuclides, which does not exceed the technogenic irradiation effective doze determined for the inhabitants by the radiation safety standards 99-2009.
