METHOD OF PRODUCING NANOSTRUCTURED TARGET FOR PRODUCTION OF RADIONUCLIDE MOLYBDENUM-99 Russian patent published in 2020 - IPC G21G4/00 B82B3/00 

FIELD: technological processes.

SUBSTANCE: invention relates to a method of producing a nanostructured target for producing radionuclide molybdenum-99 and can be used to produce radionuclide molybdenum-99 (99Mo) high specific activity (without carrier), which is the basis for creation of radionuclide generators of technetium-99m (99mTc), having wide application in nuclear medicine for diagnostic purposes. Production of radioisotope ⁹⁹Mo is carried out by reaction of ⁹⁸Mo (n,γ) and ¹⁰⁰Mo (γ,n). Isotope is obtained in form of a matrix of activated alumina with cavities and channels with characteristic dimensions lying in range of 2-50 nm. Nano-layer of molybdenum-containing substance is applied on surface of cavities and channels, thickness of which is less than length of path of recoil atoms of ⁹⁹Mo in substance of nanolayer. Nanolayer of molybdenum-containing substance used is water-insoluble aluminum molybdate (Al₂[MoO₄]₃).

EFFECT: simple procedure of extracting radionuclide ⁹⁹Mo.
