The paper is devoted to the problem of gamma-ray transport in the most used reactor building materials. Now there are conciderably discrepancy bitween measured and calculated gamma-ray spectra leaking from iron, lead and chromium specimens with neutron source in the centre. Shown that discrepancies may be caused by constants errors of photons transport, radiative neutrons capture and nonelastic neutrons scattering. To provide support these assumptions it is necessary to investigate the energy-angular
photons spectra at neutrons capture end nonelastic neutrons scattering for variety of materials and different neutrons spectra.
