“…In our earlier experiments aimed at studying the possibilities of the Szilard‐Chalmers method for 99 Mo production via irradiation of molybdenum compounds with protons, encouraging results have been achieved. Two different types of targets, having submicron particles (ie, greater than or equal to 100 nm) of molybdenum compounds, have been irradiated with a cyclotron proton beam.…”

We study the possibility of increasing the specific activity of 99Mo produced by irradiating molybdenum targets with the use of the Szilard‐Chalmers effect. According to the Szilard‐Chalmers effect, recoil atoms of the 99Mo radionuclide can be produced in nuclear reactions and retained in surrounding buffer substance. The objective of our work is to measure the yield of recoil atoms in the buffer as a function of the molybdenum layer thickness. The yield of recoil 99Mo atoms in the 100Mo(p,x)99Mo nuclear reaction as a function of metallic molybdenum nanolayer thickness has been measured. Measurements were carried out after irradiation of nanolayers in the U‐150 cyclotron with 28‐MeV protons. Nanolayers of molybdenum with thickness of 30 to 220 nm were produced by magnetron sputtering on sapphire plates. The yield of the mass of 99Mo recoil atoms was found to be the highest with the molybdenum layer thickness of 80 ± 5 nm. The enrichment factor (EF) has been defined as a ratio of the 99Mo collector specific activity (SA) to the entire target SA before separation as EF = 1200 ± 150. The specific activity of 99Mo produced in the collector was estimated to be approximately equal to 25 Ci·g−1.

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.
