METHOD OF OBTAINING RADIOISOTOPE MOLYBDENUM-99 Russian patent published in 2015 - IPC G21G1/08 G21G4/08

Abstract RU 2554653 C1

FIELD: chemistry.

SUBSTANCE: method of obtaining radioisotope ⁹⁹Mo includes the irradiation of a target by a beam of neutrons with the following extraction of the target radioisotope, formed as a result of a ⁹⁸Mo(n,γ)⁹⁹Mo reaction. As the target applied are nanoparticles of metallic molybdenum or its compounds, insoluble in water, or a water solution of alkali, or water NH₄OH solution. Irradiation of the target is carried out in water, or water alkali solution, or water NH₄OH solution. The target radioisotope ⁹⁹Mo is separated in the composition of an anion of water-soluble molybdate(⁹⁹MoO₄)^-2 from nanoparticles.

EFFECT: increase of the specific activity of ⁹⁹Mo radioisotope.
