Abstract

The possibility production of 99Mo radioisotope with using recoil nuclei of molybdenite nanoparticles from reaction 100Mo(γ,n)99Mo was investigated. The use of thermally stable molybdenite allows solving the problem of thermal loads of high-power electron beams. The enrichment of radioactive isotopes carried out by the effect of SzilardChalmers. Molybdenite nanoparticles were irradiated by bremsstrahlung with Emax=39 MeV. The recoil nuclei of 99Mo separated by electrolysis at low concentration. The yield of 99Mo from extractable phase amounted 3% for size nanoparticles 350 nm.
