In this regard, scientific research is regularly carried out in these territories, the results of which can be used to determine and analyze radiation and environmental risk. The goal and objective of the work is to calculate integral indicators of radionuclide pollution and generalized indicators of radiation-ecological risks in water and bottom sediments of the Barents and Kara Seas areas exposed to nuclear and radiation hazardous facilities. It is shown that the index ranges from 9.5·10-5 to 4.1·10-4 for water and from 1.2·10-4 to 1.3·10-2 for bottom sediments, which is much less than one. Calculated values of the risk indicator for K-159 range from 3 to 6, which corresponds to an insignificant radiation impact on the marine environment, for bays and the Novaya Zemlya depression from 12 to 18, which is characterized by a weak impact on the radiation situation. Thus, the objects under assessment have an insignificant and weak impact on the radiation situation in the Arctic region, but, taking into account the potential danger, they require constant monitoring of the components of the marine environment in order to timely detect radiation-ecological changes.</p></abstract><trans-abstract xml:lang="ru"><p>Большая часть потенциальных источников радиоактивного загрязнения Арктики находится в Баренцевом и Карском морях. В связи с этим на указанных территориях регулярно проводятся научные исследования, результаты которых могут использоваться для определения и анализа радиационно-экологического риска. Целью и задачей работы является расчет интегральных показателей загрязнения радионуклидами (ИПЗ) и обобщенных показателей радиационно-экологических рисков (ОПР) в воде и донных отложениях районов Баренцева и Карского морей, подверженных воздействию ядерно и радиационно опасных объектов (ЯРОО). Показано, что ИПЗ составляет от 9,5·10-5 до 4,1·10-4 для воды и от 1,2·10-4 до 1,3·10-2 для донных отложений, что на много меньше единицы. Расчетные значения ОПР для К-159 составляют от 3 до 6, что соответствует незначительному радиационному воздействию на морскую среду, для заливов и Новоземельской впадины от 12 до 18, что характеризуется слабым воздействием на радиационную обстановку. Таким образом, объекты оценки оказывают незначительное и слабое воздействие на радиационную обстановку в Арктическом регионе, но, с учетом потенциальной опасности, нуждаются в постоянном мониторинге компонентов морской среды для своевременного выявления радиационно-экологических изменений.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Arctic</kwd><kwd>radiation-ecological risk</kwd><kwd>integral indicator of pollution</kwd><kwd>reference level</kwd><kwd>marine biota</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>Арктика</kwd><kwd>радиационно-экологический риск</kwd><kwd>интегральный показатель загрязнения</kwd><kwd>контрольный уровень</kwd><kwd>морская биота</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Sivintsev YuV, Vakulovsky SM, Vasiliev AP.
