METHOD TO PRODUCE RADIOISOTOPE STRONTIUM-82 Russian patent published in 2012 - IPC G21G1/10 

FIELD: power engineering.

SUBSTANCE: method to produce radioisotope strontium-82 includes radiation of α-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 ^{80,82,83,84,86}Kr(α,xn)⁸²Sr or accordingly one or more threshold nuclear reactions ^{80,82,83,84,86}Kr(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.
