Материалы и методы: Объектами исследований были 11 видов типичных представителей ихтиофауны Полесского государственного радиационно-экологического заповедника (ПГРЭЗ). Удельная активность137Cs измерялась методом гамма-спектрометрии,90Sr - инструментальным или радиохимическим методом. Результаты. Исследовано накопление137Cs и90Sr тканями рыбы в водоемах ПГРЭЗ в зависимости от их типа. Установлены достоверные отличия между аккумуляцией137Cs хищными и рыбами с другим типом питания. Выявлено, что удельная активность137Cs в мышечной ткани рыбы в 1,4-1,6 раза превышает накопление радионуклида в костной и жировой ткани. Для90Sr характерна наибольшая аккумуляция в костной ткани, где его удельная активность до 16 раз выше по сравнению с мышечной тканью. Оценка возможной дозы внутреннего облучения от употребления рыбы из загрязненных водоемов показала, что она составит от 0,01 до 0,07 мЗв/год и до 2 мЗв/год - из непроточных водоемов. Заключение: Проведенные исследования подтвердили необходимость жесткого радиационного контроля пресноводной рыбы в районах, пострадавших от аварии на Чернобыльской АЭС.</p></abstract><trans-abstract xml:lang="en"><p>Objective: to investigate the accumulation of137Cs and90Sr in the tissues of various species of fish from different types of the water bodies within the Belarusian sector of the Chernobyl NPP Zone of Alienation and to assess the potential dose loads on the population consuming the fish from the contaminated water bodies. Material and methods: 11 species of the typical representatives of the ichthyofauna of the Polesye State Radiation-Ecological Reserve (PSRER) were the objects of the research. The specific activity of137Cs was measured by the method of gamma-ray spectrometry,90Sr - by the instrumental or radiochemical method. Results: The accumulation of137Cs and90Sr in the tissues of the fish in the water bodies of the PSRER depending on their type has been studied. The study has found reliable differencies between the accumulation of137Cs by predatory fish and fish with other types of nutrition. It has been revealed that the specific activity of137Cs in the muscle tissue of the fish is 1.4-1.6 times higher than the accumulation of the radionuclide in their bone and adipose tissues.90Sr is characterized by its highest accumulation in the bone tissue, where its specific activity was as up to 16 times as high as that of the muscle tissue. The assessment of the possible dose of internal irradiation following the consumption of the fish from the polluted water bodies has showed that it will be from 0.01 to 0.07 mSv/year and up to 2 mSv/year from stagnant water bodies. Conclusion: The studies have confirmed the necessity of strict radiation control of freshwater fish in the areas affected by the Chernobyl NPP Accident.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>доза</kwd><kwd>радионуклиды</kwd><kwd>рыбы</kwd><kwd>пресноводные водоемы</kwd><kwd>внутреннее облучение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>137Cs</kwd><kwd>90Sr</kwd><kwd>dose</kwd><kwd>radionuclides</kwd><kwd>137Cs</kwd><kwd>90Sr</kwd><kwd>fish</kwd><kwd>freshwater bodies</kwd><kwd>internal exposure</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title></ref-list><fn-group><fn fn-type="conflict"><p>The authors declare that there are no conflicts of interest present.</p></fn></fn-group></back></article>
