| description | Based on the results of Monte Carlo calculations of the spatial energy distributions of photons in iron from point isotropic and planar mononirectional monoenergy sources with energies of 10-50 MeV, the air Kerma attenuation multiplicities and dose accumulation factors of the material under consideration are determined.. The calculations take into account the contribution of the fluorescence, annihilation radiation and bremsstrahlung. The independence of the accumulation factors from the angular distribution of the source radiation is shown, and the independence of the attenuation multiplicities from the angular distribution of the source radiation and the weak dependence on its energy in the energy range 30-50 MeV is also shown. The corrections for the barrier protection are determined and their independence from the thickness of the protection and the photon energy of the source is noted. The obtained information allows to reduce the errors of the results of calculations of the thickness of anti-radiation protection of electronic accelerators at high energies, using developed engineering methods of calculation. The obtained information can also be used in calculations of protection against brake radiation of electronic accelerators by engineering methods. |
