METHOD TO PRODUCE RADIONUCLIDE Mo Russian patent published in 2011 - IPC G21G1/00 

FIELD: power engineering.

SUBSTANCE: method to produce a radionuclide ⁹⁹Mo, including radiation of a start material with neutrons and subsequent release of activation isotopes, differing by the fact that the start material is represented by refractory radiation and heat resistant compounds of molybdenum with particle size of (5÷100)×10^-9 m, the start material is radiated with neutrons with flow density of more than 10¹⁴ cm^-2s^-1 for 7÷5 efficient days, and activation isotopes are extracted from the surface layer of the start material by dissolution of this layer in acid or alkali, or a mixture of acids, or a mixture of alkalis.

EFFECT: production of isotopes ⁹⁹Mo of high specific activity with multiple usage of the start material, without generation of highly active wastes, which will make it possible to organise economically efficient large-scale production of isotope ⁹⁹Mo.
