Foodstuff contamination and pattern of consumption by population of foremost radioactively contaminated territories in Ukraine during the remote period of the Chornobyl disaster clean-up.

Objective. The goal of the study was to estimate, from the perspective and in terms of hygienic provisions, the level of local food contamination by 137Cs and their pattern of consumption by residents of foremost radionuclide contaminated territories of Ukraine (Zhytomyr, Kyiv and Rivne oblasts) in the remote period of the Chornobyl disaster. Materials and methods. The article presents analytical data from the National Statistics Office of Ukraine concerning production and consumption of agricultural products in the territories of foremost severe radioactive contamination (TRC) i.e. Zhytomyr, Kyiv and Rivne oblasts (provinces). Data on levels of food contamination (milk, meat, fruits and vegetables, wild mushrooms and berries) received from the regional radiological control centers (RCC) and sanitary and epidemiological agencies/bureaus (SEA) were analyzed. According to results of questionnaire survey of residents in TRC of investigated regions (oblasts) the public awareness of radioactive contamination levels in local food production, their level of consumption and the use of cooking measures to reduce internal dose were assayed. Analytical, mathematical, statistical, sociological, and software engineering methods were applied. Results and conclusions. It was found that in the country and in study areas as well there is more than a half decrease of milk and meat production and consumption, and almost half times increased production of potato. It was shown that locally produced food and wide use of wild berries and mushrooms are dominated in the diet of TRC residents in the remote period after the Chornobyl disaster. Ecological and hygienic monitoring of foodstuffs in TRC proves the probability of product consumption with high content of radioactive materials. Residents territories of the foremost severe radioactive contamination in Zhytomyr, Kyiv and Rivne oblasts are aware about possible contamination of locally produced food with substances of Chornobyl origin and about the ways to reduce the contamination by means of cooking. In order to reduce the levels of possible internal exposure to radiation in population of TRC the agricultural amelioration and monitoring of radioactive contamination of wild and agricultural products should be continued.
