ANALYSIS OF RESULTS OF RESEARCH OF FOOD PRODUCTS AND FEED CONTAMINATED BY CS-137 AND SR-90 RADIONUCLIDES IN THE ZHITOMIR AND RIVNE REGIONS IN 2013–2019

Introduction. The Chernobyl tragedy has caused environmental catastrophe in Zhytomyr and Rivne regions, and main pollutants were cesium-137 and strontium-90 radionuclides. Ukraine carries out radiological control and monitoring of food and feed safety on these radionuclides detection.

The goal of the work. Analysis of the results of food and feed tests on the content of 137Cs and 90Sr radionuclides from 2013 to 2019 in Zhytomyr and Rivne regions. Determination of critical dose-forming food products and determine their dynamics of contamination.

Materials and methods. Reports of radiological tests of 137Cs and 90Sr radionuclide content provided by radiological departments of regional state laboratories of Zhytomyr and Rivne of State Service for Food Safety and Consumer Protection of Ukraine. Radiometric and spectrometric research methods, were used in our work.

Results of research and discussion. The reports of radiological studies of 2 580 814 samples of food products and feed on the content of cesium-137 and strontium-90 radionuclides were analyzed. We have found that the major dose-generating radionuclide in these regions was 137Cs; the 90Sr radionuclide was not detected in the samples. The maximum permissible level of 137Cs was exceeded in 2250 samples, namely in forest mushrooms and berries (fresh and dried) – 55.7%, cattle milk – 31.1%, and wild animal meat – 9.2%. In other products and feeds, exceeding the limit of 137Cs radionuclide was almost 1% of the total number of positive samples.

Conclusions and prospects for further research. Сesium-137 is the main dose-forming radionuclide and food contaminant in Zhytomyr and Rivne regions. The critical dosage products are mushrooms and berries (fresh and dried), cattle milk, wild animal meat. Prospects for the solution of this problem are to continue radiological control in radioactively contaminated territories and use of radiation protection measures.

Keywords: pollution, 137Cs and 90Sr radionuclides, maximum permissible level, food products, feed.
