Procedures: dosimetric (instrumental and numerical evaluation methods), radiochemical. Results: inhabitants from three settlements in Polisky region of Kyiv oblast were monitored to assess internal content levels of 137Cs, 90Sr. Main victuals and urine assays were collected to assess internal exposure dose due to 137Cs, 90Sr intake in winter-spring and summer-autumn periods. There were observed radionuclides accumulations over the whole year, maximum value was 150732 Bq (Ragivka village ). The relative number (%) of inhabitants with annual dose over permissible level of 1 mSv raised from 9.4% to 17.9% (Ragivka village) and from 1.3 to 2.4 (Zelena Polyana). The content levels of 137Cs and 90Sr in main victuals (milk, potatoes) harvested in the selected settlements regions were below permissible levels. Victuals from forests (berries, mushrooms) had been contaminated by cesium dozen times of permissible levels.
