METHOD OF PRODUCING STRONTIUM-82 RADIOISOTOPE Russian patent published in 2016 - IPC G21G1/10 G21G4/00

Abstract RU 2585004 C1

FIELD: medicine; physics.

SUBSTANCE: invention relates to technology of producing radioisotopes for nuclear medicine on charged particle accelerators. Method of producing strontium-82 (⁸²Sr) radioisotope by reaction of Rb(p,xn)⁸²Sr includes irradiating target by protons, such as solution or melt of one or more chemical compounds of rubidium or their suspension in liquid carrier, and their circulation in closed circuit through protons irradiation area, gaining in target at reaction ⁸⁵Rb(p,4n)⁸²Sr and (or) reaction ⁸⁷Rb(p,6n)⁸²Srradioisotope ⁸²Sr, and extraction of ⁸²Sr from irradiated target after irradiation or directly during exposure using radiochemical method.

EFFECT: invention provides low explosion hazard of method, expansion of functionality, possibility to use multiple target device, excluding costs for its production and possibility of automating process.
