The capture efficiency of 99Mo nuclei in nanoparticles was investigated by Monte Carlo simulation. It is shown that for photon
incident energies, photon energies in the 12–18 MeV range capture almost all of the molybdenum-99 recoil nuclei emitted from
the nanoparticles in the carrier particles. The total number of 99Mo nuclei reaching the carrier particles is less than 1.5% of the
total 99Mo nuclei emerging from the nanoparticle. To achieve high specific activity of 99Mo formed, optimization of the
concentration of clinoptilolite nanoparticles in suspension is required. The possibility of obtaining the 99Mo radioisotope using molybdenite nanoparticle recoil nuclei has been investigated. The use of heat-resistant molybdenite can solve the problem of heat loads of powerful electron beams. Enrichment of radioactive
isotopes was carried out using the Scilard-Chalmers effect. Molybdenite nanoparticles were irradiated with bremsstrahlung
with Emax = 39 MeV. 99Mo recoil nuclei were separated by electrolysis at low concentration. The yield of 99Mo from the
extracted phase was ~ 3% for nanoparticles with a size of 350 nm. Studies have shown that technical conditions using existing (or upgraded) acceleration technology can produce up to 3 Ki 99mTs in the form of sodium pertechnetate in one day. The main problems were solved using an electron accelerator with energies above 12 MeV to irradiate the target with nanoparticles.
