| Popis: | Purpose. The aim of this paper is to simulate the spectrum of reflected neutron radiation when a primary monoenergetic neutron beam (1 MeV) falls on a concrete surface. Methods. Computer modeling using Monte Carlo method. Findings. The spectra of the reflected radiation are calculated when the neutron beam hits the surface of the concrete. The maxima in the spectra are identified with the elemental composition of concrete Application field of research. The obtained results can be used for energy spectrum estimations of the reflected neutrons in the bunker of the medical electron accelerator. Conclusions. The processes of neutron scattering in concrete, leading to the formation of reflected radiation, shift the neutron energy into the low-energy region. The largest energy shift of the peak of the neutron spectrum is observed for the perpendicular incidence of the neutron beam on a concrete wall. |
