Simulation of $^{67}$Cu photo-nuclear production in nanoparticles
  The process of $^{67}$Cu nuclide photoproduction in the zinc dioxide nanoparticles immersed in the water media was simulated. We calculated the escape fractions of $^{67}$Cu nuclei and corresponding ranges in water for nanoparticle sizes from 40 nm to 80 nm and incident photons energies from 12 MeV to 30 MeV. Usage of capturing nanoparticles for accumulation of the escaped $^{67}$Cu nuclei is also discussed.
