METHOD OF PRODUCING NANOSTRUCTURED TARGET FOR PRODUCTION OF MOLYBDENUM-99 Russian patent published in 2018 - IPC G21G1/08 B82B1/00 

FIELD: physics.

SUBSTANCE: invention relates to a technology for the production of radionuclides and can be used for the production of a high specific activity molybdenum-99 radionuclide (without a carrier), which is the basis for the production of radionuclide generators of technetium-99, which have found wide application in nuclear medicine for diagnostic purposes. Method is realized by using as a target a mesoporous inorganic material – activated carbon, with characteristic cavities and channels sizes up to 50 nm, on the surface of which successive layers of MoO₃ and a water-soluble compound, for example KCl or NaCl. After this, coal is burned in oxygen, resulting in a small, homogeneous, two-component mixture of MoO₃ and KCl or NaCl. At the last stage, the conversion of MoO₃ in a water soluble compound MoO₂ is carried out.

EFFECT: invention makes it possible to increase the enrichment factor of ⁹⁹Mo.
