INFLUENCE OF MECHANICAL TREATMENT AND X-RAY IRRADIATION OF LiF CRYSTALS ON THEIR PHOTOMETRIC AND COLORIMETRIC CHARACTERISTICS

Based on the study of the optical absorption spectra τλ(λ) of LiF crystals with a residual deformation value of ε = 0.8% with different irradiation doses up to ~ 103 R, a colorimetric analysis of the radiation of the visible region of the spectrum passing through the crystals was carried out. It has been established that with an increase in the radiation dose at a fixed value of ε, neither the photometric characteristics nor the color of the radiation passing through the crystal medium change.
