In the GEANT 4.9.2 the interaction of the primary X-rays electromagnetic radiation with the secondary converter atoms was calculated, K-lines yields of characteristic X-rays radiation (CXR) were computed. Spectra of the primary radiation NRENT(E) = f (E) was simulated, analogous to the shape of the bremsstrahlung of electrons in crystals. X-rays were sent to the secondary target and excited the CXR, which was registered by the detector at angels 90º-180º. The ratio XRENT(E) yield of intense X-ray bremsstrahlung radiation from oriented crystal to the yield of a disoriented crystal was determined (axis/random). The ratio (axis/random) of yields XCXR(E) from secondary targets in the energy range 7-115 keV were calculated. The energy dependence XRENT(E) и XCXR(E) were compared. Shown that recovery of low-energy bremsstrahlung spectra of channeled electrons is possible when the radiation spectrum of channeled electrons has a monotonous dependence with no complex structure.
