Objective: Determination of the main internal irradiation dose forming factors for residents from contaminated areas in Rivne oblast based on comprehensive dosimetric monitoring in supervised settlements. Methods: dosimetric (instrumental and calculated), radiochemical. Results: WBC-monitoring showed lower levels of internal exposure to settlements surveyed from 2011 to 2014. 30-40% and almost no seasonal formation of internal exposure in 2014. The content of 137Cs in milk products and forest products origin (primarily, mushrooms and berries) is much higher than the permissible level. Revealed that the concentration of 137Cs in milk samples taken in May, 1.5-2 times higher than in the October samples. But that does not give effect of the level of exposure, as offset seasonal 137Cs from forest products origin. It should be noted that no potato sample did not exceed the permissible levels of radionuclides 137Cs. The most polluted state of emergency in the examined products are dried mushrooms, 137Cs concentration in them exceeds acceptable levels scores times. The content of 90Sr in samples collected all the products below or at the level of sensitivity of the method (LSM = 0.3 Bq • kg-1) and does not make a significant contribution to the formation of radiation dose. All the above indicates the need to ensure the population of the settlements of emergency the possibility of permanent radiation monitoring critical of radioactive contamination of foodstuffs - milk and forest products origin for the content of 137Cs and WBC-measurements population.
