Abstract

1. Способ генерации радиоизотопов, используемых в ядерной медицине для приготовления фармпрепаратов, вводимых в пациента, как открытые радиоактивные источники, включающий облучение мишени пучком тормозного излучения и извлечение из мишени образовавшихся радионуклидов методами радиохимии, отличающийся тем, что используют мишень и ядерные реакции, протекающие в мишени, которые приводят к образованию ядер химических элементов, отличных от химических элементов мишени по атомному номеру на 1 или 2, при этом тормозное излучение генерируется электронным пучком с энергией 40-60 МэВ и при средних токах от десятков мкА в радиаторе толщиной от десятых до одной радиационной длины для материала радиатора.2. Способ по п.1, отличающийся тем, что ядерные реакции, которые приводят к образованию ядер химических элементов, отличных от химических элементов мишени, протекают в одну или две последовательные стадии.1. The method of generating radioisotopes used in nuclear medicine for the preparation of pharmaceutical products introduced into the patient as open radioactive sources, including irradiating the target with a beam of bremsstrahlung and extracting the generated radionuclides from the target using radiochemistry methods, characterized in that they use the target and nuclear reactions proceeding in targets that lead to the formation of nuclei of chemical elements other than the chemical elements of the target by an atomic number of 1 or 2, while the bremsstrahlung is generated an electron beam with an energy of 40-60 MeV and with average currents from tens of μA in a radiator with a thickness of tenths to one radiation length for the radiator material. 2. The method according to claim 1, characterized in that the nuclear reactions that lead to the formation of nuclei of chemical elements other than the chemical elements of the target proceed in one or two successive stages.
