Applying the set of experimental techniques including dose effect of 60Co γ-quanta, X-ray diffraction, local element analysis on microscale, scanning probe microscopy, optical and FTIR spectroscopy, the Cl deficit and the related NaClО3 and Na2О impurity phases were determined quantitatively >80 wt% in the subsurface nanolayer of optically pure polished NaCl crystal. Under the irradiation in air at 320 K to doses 0.4−30 MR the radiolysis of the impurity phases proceeds with losses of 15 wt% Cl and formation of >80 wt% NaH phase with nano[1]cone shape and NaOH nanofilm. These nanophases are suggested to come from absorption of ∼1.25 MeV γ-quanta by Cl nuclei followed by nuclear reaction 35Сl17→16О8+18О8+1 Н1. It was found that at saturation of F-centers they interact and the corresponding absorption band split into doublet at dose ∼0.7×106 R that is explained by Mie theory of light scattering at metal nanoparticles in dielectrics. FTIR spectra showed significant weakening of stretching vibration of Na-Cl bonds at 620 cm−1 due to Cl-loss and emerging additional bands at higher wave numbers attributed to structure defects and impurity phases. Their γ-dose behavior correlates with the XRD data. Since NaH and NaOH are electroconducting, such a nanostructured surface of NaCl can be applied for high radioactive waste deposit with production of electricity
