The use of molybdenum oxide nanoparticles for production of free isotope Mo-99
The possibility of photonuclear production of ⁹⁹Mo medical radioisotopes using recoil nuclei of nanoparticles MoO₃ from reaction ¹⁰⁰Mo(γ,n)⁹⁹Mo was investigated. (γ,n)-reaction does not be accompanied by change in nuclear charge. Therefore, the enrichment of radioactive isotopes is being carried out...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | The possibility of photonuclear production of ⁹⁹Mo medical radioisotopes using recoil nuclei of nanoparticles MoO₃ from reaction ¹⁰⁰Mo(γ,n)⁹⁹Mo was investigated. (γ,n)-reaction does not be accompanied by change in nuclear charge. Therefore, the enrichment of radioactive isotopes is being carried out using methods based on the effect of Szilard-Chalmers. The highest concentration of ⁹⁹Mo is required for manufacturing of ⁹⁹mTc-⁹⁹Mo generators. These generators will promote successful using ⁹⁹mTc in nuclear medicine. MoO₃ nanoparticles of size 13…80 nm were placed in isopropyl alcohol and ethylene glycol. The colloidal solution of MoO₃ is achieved by sonication. The colloidal solution of nanoparticles of MoO₃ was irradiated by bremsstrahlung with Emax = 12.5 MeV. The recoil nuclei of ⁹⁹Mo were separated by means of diantipyrylmethane in sulfuric acid solution. Yield of ⁹⁹Mo from extractable phase amounted ~ 4%, in consequence of the high density of MoO₃ nanoparticles in a colloidal solution. |
