К редкоземельным элементам (РЗЭ) относятся 17 элементов побочной подгруппы III группы периодической таблицы химических элементов Д.И. Менделеева с атомными номерами 21, 39, 57, 58–71: скандий, иттрий, лантан и 14 лантаноидов. Некоторые радиоактивные изотопы данных элементов уже используются в медицине в качестве радиоактивной составляющей разрешенных к применению лекарственных средств, например, изотопы самария – 153Sm [<xref ref-type="bibr" rid="cit1">1</xref>] и 177Lu [<xref ref-type="bibr" rid="cit2">2</xref>], а для некоторых возможность их использования в медицине только изучается. Так, изотоп скандия – 47Sc изучается как потенциальный радиоизотоп для тераностики онкологических заболеваний [3,4], гольмий – 166Ho как изотоп для радиосиновектомии и брахитерапии [<xref ref-type="bibr" rid="cit5">5</xref>], празеодим – 142Pr перспективен для брахитерапии [<xref ref-type="bibr" rid="cit6">6</xref>]. Способность редкоземельных элементов образовывать химические связи с органическими молекулами, в том числе пептидами природного и синтетического происхождения, является основой разработки новых препаратов для адресной терапии рака молочной и предстательных желёз, нейроэндокринных опухолей, диссеминированного рака лёгких и других видов заболеваний. Для определения перечня наиболее перспективных для облучения на ректоре ВВР-К РЗЭ с целью наработки радиоактивных изотопов была проведена оценка способов наработки радиоактивных изотопов и анализ их ядерно-физических характеристик по литературным данным. Такие изотопы как: 166Ho, 165Dy, 90Y, 175Yb, 153Sm, 177Lu, 147Nd, 170Tm, 159Gd и 141Ce могут быть использованы в терапии онкологических заболеваний.</p><p>Данная исследовательская работа позволяет оценить возможность получения радиоизотопов РЗЭ по реакции (n, γ) на реакторе ВВР-К, а также отражает перспективы применения данных изотопов при разработке радиофармпрепаратов нового поколения для терапии онкозаболевавний.</p></abstract><trans-abstract xml:lang="en"><p>Radioactive isotopes of rare earth elements have effective nuclear-physical properties and are promising for the development of new therapeutic radiopharmaceuticals. Rare earth elements (REE) include 17 elements of the secondary subgroup of group III of the periodic table of chemical elements of D.I. Mendeleev with atomic numbers 21, 39, 57, 58–71: scandium, yttrium, lanthanum and 14 lanthanides. Some radioactive isotopes of these elements are already used in medicine, as a radioactive component of approved medicines, for example, the isotopes of 153Sm and 177Lu, and for some the possibility of their use in medicine is only being studied. Thus, the isotope scandium – 47Sc is being studied as a potential radioisotope for cancer diagnosis, holmium – 166Ho as an isotope for radiosynovectomy and brachytherapy, praseodymium – 142Pr is promising for brachytherapy. The ability of rare earth elements to form chemical bonds with organic molecules, including peptides of natural and synthetic origin, is the basis for the development of new drugs for targeted therapy of breast and prostate cancer, neuroendocrine tumors, disseminated lung cancer and other types of diseases. To determine the list of the most promising for irradiation at the rector of the WWR-K REE in order to develop radioactive isotopes, an assessment of the ways of developing radioactive isotopes and an analysis of their nuclear physical characteristics according to literature data was carried out. Isotopes such as: 166Ho, 165Dy, 90Y, 175Yb, 153Sm, 177Lu, 147Nd, 170Tm, 159Gd and 141Ce can be used in the treatment of oncological diseases. This research work makes it possible to evaluate the possibility of obtaining REE radioisotopes by reaction (n, γ) at the WWR-K reactor, and reflects the prospects for using these isotopes in the development of new-generation radiopharmaceuticals for the treatment of oncological diseases.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>редкоземельные элементы</kwd><kwd>нейтроны</kwd><kwd>радиофармпрепараты</kwd><kwd>ядерно-физические свойства</kwd><kwd>радионуклиды</kwd><kwd>реактор ВВР-К.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>rare earth elements</kwd><kwd>neutrons</kwd><kwd>radiopharmaceuticals</kwd><kwd>nuclear-physical properties</kwd><kwd>radionuclides</kwd><kwd>WWR-K Reactor</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Данная работа была профинансирована Министерством образования и науки Республики Казахстан (BR10965174)</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">United States Pharmacopoeia.
