摘要：
Thermally stimulated luminescence and optical absorption measurements were performed on NaCl single crystals, both single and double doped. The NaCl single crystals were exposed to gamma rays from a 60Co source at both low and room temperatures. The radiation-induced defects were mainly F and H centers, and the absorption bands for the F centers were centered at 464 nm. Bleaching with F-light showed the participation of the F center generated by gamma radiation on the TL phenomenon. The results suggest that NaCl single crystals, both single and double doped can be used as dosimeters, within certain doses.
