Abstract
Thermoluminescence (TL) properties were investigated in samples of qua rtz subjected to experimental impulse pressures of less than or equal to 49 GPa. The TL glow curves induced by various doses of gamma radiat ion were processed using a special software package, with which 11 Gau ssian peaks with a constant full width at half maximum were identified . The values of the TL sensitivity ratios in the low-temperature (120- 220 degrees C) and the high-temperature (290-420 degrees C) region of the glow curves are shown to be linearly dependent upon the intensity of the shock-wave effect in the 0-20 GPa pressure region with a correl ation coefficient close to unity. The shapes of the grow curves were f ound to be a function of the total irradiation dose, which is characte rized by the presence of an intense TL peak with a temperature of the maximum equal to ca. 360 degrees C in samples subjected to pressures o f <24 GPA. The results justify the conclusion that a barometric scale based on TL properties has been established for the quartz samples.
