The possibility of photonuclear production of 99Mo medical radioisotope using recoil nuclei of molybdenite nanoparticles from reaction 100Mo(γ,n)99Mo was investigated. The enrichment of radioactive isotopes is carried out by the effect of Szilard-Chalmers. Molybdenite nanoparticles were irradiated by bremsstrahlung with Emax = 39 MeV. The recoil nuclei of 99Mo are separated by electrolysis. The yield of 99Mo from the extractable phase amounted to ~3%. This technology will allow producing 0.8 GBq/g of 99mTc with high specific activity per day. Key words: linear electron accelerator, photonuclear production, electrolysis, specific activity, recoil nuclei, molybdenite nanoparticles. |
