LiF crystals were irradiated with 60Co γ rays at 25℃ and - 70℃ respectively. Dose ranged from 5.1×102 to 1.3×105Gy. Optical absorption spectra and positron annihilation radiation Doppler broadening were measured at room temperature. The changes of F center concentration and S parameter with dose were given and the results were discussed.
