In this article we have shown that it is possible to use transmission,
absorption and reflection spectroscopic data of KClxBr1-x single
crystals for the TL (Thermo Luminescence) dosimetry purposes in the spectral
range of 250-750 nm. The effects of gamma radiation on KClxBr1-x single crystals were investigated by radiating the samples with a 60Co
source and studying the reflection and absorption spectra. Six doses of
gamma radiation of 145, 300, 450, 600, 750 and 900 Gy were examined. The
absorption peak height in the spectral region of 560-580 nm is in a direct
relationship with the gamma radiation doses up to about 800 Gy, in which
saturation starts to occur. The intensities of the color centers in mixed
crystals are different by their combination ratios of the components
contents. According to the reflection and transmission data, the absorption
spectra can be calculated and a calibration curve sketched.
