FIELD: power engineering. ^ SUBSTANCE: method to produce radioisotope strontium-82 includes radiation of -particles or 3He target from krypton by accelerated beams. The target is one isotope or cascade from several isotopes of crypton, every of which represents crypton enriched by i isotope to concentration that exceeds concentration of i isotope in natural mix of crypton isotopes, and simultaneously exceeding concentration of any other isotope in mixture of crypton isotopes, at the same time crypton isotopes in the cascade are arranged in series in direction of the accelerated particle beam in the decreasing order of atomic masses of isotopes having maximum concentration in the mixture of crypton isotopes, and in process of one or more threshold nuclear reactions 80,82,83,84,86Kr(,xn)82Sr or accordingly one or more threshold nuclear reactions 80,82,83,84,86Kr(3He,xn)82Sr, the target radioisotope 82Sr is accumulated in the target. ^ EFFECT: invention makes it possible to increase yield of target radioisotope 82Sr and provides for control and minimisation of the value of accompanying activities of the main interfering admixtures 85Sr and 83Sr. ^ 2 cl, 1 dwg |
