METHOD OF PRODUCING ENRICHED RADIOACTIVE ISOTOPE KRIPTON-85 Russian patent published in 2019 - IPC G21G1/10 

FIELD: chemistry.

SUBSTANCE: invention relates to separation of isotopes and relates to production of enriched radioactive isotope krypton-85 gas by centrifugal method from small amount of initial isotope mixture. Disclosed is a method of producing an enriched radioactive isotope krypton-85 using a gas centrifuge method from a small amount of an initial isotope mixture containing krypton-85. For cascade filling and adjustment of its optimal parameters before each stage of enrichment of krypton-85 there used is isotope mixture, which is krypton with natural isotopic composition.

EFFECT: invention reduces losses of the initial isotope mixture, increases extraction of krypton-85 from the initial mixture.
