EVALUATION OF THE CONTENT OF 137Cs RADIONUCLIDE IN FOOD PRODUCTS OF FOREST ORIGIN OF RESIDENTS OF RADIOACTIVELY CONTAMINATED TERRITORIES IN THE LONG-TERM PERIOD AFTER THE CHERNOBYL ACCIDENT
Abstract
21A, Myru Av., Zhytomyr, 10020, Ukraine The article presents the material of the investigation of the foodstuff of forest origin which is a part of a diet of residents in the settlements in Ovruch and Narodychi raions of Zhytomyr region that are classified as the 2nd and the 3rd zone of radioactive contamination. For the investigation, boletuses and bilberry were sampled in these settlements, since they are an indispensable part of diets of people that live in the radioactively contaminated areas after the Chornobyl accident. The measurement of the 137Cs content in the selected samples was carried out using the spectrometric method at the universal spectrometric complex “Gamma Plus” in the measuring laboratory of the Zhytomyr Branch of the State Institution “Institute for Soil Protection UKRAINE”. It was found out that boletuses (dried) and berries sampled in villages Rudnia and Vystupovychi were characterized by the highest contamination with radiocesium compared to other samples of the foodstuff of forest origin taken in the settlements in Ovruch and Narodychi raions. The specific activity of 137Cs in boletuses (dried) sampled in this area exceeded the maximum permissible level by 3.2-5.1 times. The other samples of boletuses (dried) taken in other settlements in Ovruch raion were within the permissible standards. The contamination of berries sampled in the settlements in Ovruch raion exceeded the permissible standards. The foodstuff of forest origin which was examined for the 137Cs content considerably exceeded MAC in all settlements in Narodychi raion. It is absolutely unacceptable to use foodstuff of forest origin of the residents of the investigated settlements in Ovruch and Narodychi raions, since the systematic consumption of foodstuff even with a low content of radiocesium leads to its accumulation in the human body, which can have a negative impact on health and cause a disease over time.
