Study the Effect of Heavy Elements Nanoparticles in the Photons Energy Spectrum in a Tissue-Equivalent Medium

Abstract:

The effect of the tantalum, platinum and gold nanoparticles on the energy distribution of the high-energy photons in the tissue-equivalent media is studied. It was shown that the presence of nanoparticles results in emergence in the medium of the electron-positron pairs manifesting in the decrease in the number of the primary photons and emergence of the secondary photons with energies of 511 keV and lower.
