Radionuclides contamination of food, animal and vegetable origin in Rivne region
Due to ill-considered and illiterate management, a significant territory of Ukraine is on the verge of an ecological catastrophe. One of the most revealing examples is the accident at the Chernobyl nuclear power plant, which occurred in 1986 year. As a consequence, significant contamination with radioactive substances of the Ukrainian Polesye and the territories of other states. The Rivne region is one of the most affected areas in the Chernobyl accident. The area of the affected area is 11.2 thousand km<sup>2</sup>, or 56% of the entire territory of the region. The radioactive contamination zones include 341 settlements located in Bereznovsky, Vladimiretsky, Dubrovitsky, Zarechny, Rokitnovsky and Sarnensky districts. Thirty-one years after the accident at the Chernobyl nuclear power plant, the radiological situation underwent some positive changes due to natural processes (physical decay of radionuclides, their redistribution in various components of the environment), as well as a set of activities that were sent immediately after the accident, to assess the state of radioactive contamination of the environment natural environment and control of the content of radionuclides in products that were produced in contaminated areas. However, the situation remains extremely difficult, food (milk, meat of wild and domestic animals, mushrooms and berries), feed for farm animals is contaminated with radionuclides, in particular cesium (<sup>137</sup>Cs), which is a danger to human health. The article determined which areas the highest content of radionuclides in food and feed was recorded. These are Bereznivskyi, Volodymyretsky, Dubrovytsky, Zarichnensky, Rokitnivsky and Sarnensky districts, where the excess was found in practically all types of products and feeds - fish, meat of domestic and wild animals, milk of cow's whole, fresh and dry mushrooms, wild berries, and also in feed for productive animals. In Dubensky, Rivne, Zdolbuniv, Demidov, Mlynivskyi, Goshchankу, and Koretsky districts there were significantly fewer excesses. Significantly better strontium situation. During the investigated period there was no excess of the content of strontium in the products.
