В настоящее время для наработки материнского изотопа 99Mo на исследовательском реакторе ВВР-К используется оксид молибдена природного состава, но по мере увеличения потребности клиник Казахстана в генераторах 99mTc, встает вопрос об использовании дорогостоящего оксида молибдена, обогащенного изотопом 98Mo, поэтому возникает задача регенерации облученного молибдена. В работе представлены экспериментальные данные по выбору оптимальной системы выщелачивания для выделения молибдена98 из отработанных 99Mo/99mTc – генераторов.</p></abstract><trans-abstract xml:lang="en"><p>The production of the radiopharmaceutical “Sodium pertechnetate 99mTc, solution for injection” from the transported 99mTc generator is a complex multi-stage process that includes the collection and disposal of radioactive waste generated at various technological stages of production, as well as after the return of the generator used in clinics. Currently, natural molybdenum oxide is used for the development of the parent isotope 99Mo at the WWR-K reactor, but as the need for 99mTc generators in Kazakhstan increases, the question arises about the use of expensive molybdenum oxide enriched with the isotope 98Mo, therefore, the task of regenerating irradiated molybdenum arises. The paper presents experimental data on the choice of an optimal leaching system for the isolation of molybdenum-98 from spent 99Mo/99mTc generators.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>99Mo/99mTc – генератор</kwd><kwd>радиохимия</kwd><kwd>отработанное сырьё</kwd><kwd>переработка</kwd><kwd>выщелачивание</kwd><kwd>молибден-98</kwd></kwd-group><kwd-group xml:lang="en"><kwd>99Mo/99mTc generator</kwd><kwd>radiochemistry</kwd><kwd>waste raw materials</kwd><kwd>processing</kwd><kwd>leaching</kwd><kwd>molybdenum-98</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Работа выполнена при финансовой поддержке Комитета науки Министерства науки и высшего образования Республики Казахстан в рамках программы грантового финансирования по научным и научно-техническим проектам № AP19679975</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Kelmar R., Manukyan K.V., Simon A., Aprahamian A.
