Abstract
Red thermoluminescence (TL) emission from quartz has attracted considerable attention in the fields of retrospective dosimetry and luminescence dating, due to the high dose saturation level and long-term stability of the TL signal. For two red emission quartz samples of volcanic origin (Yuda sample from Iwate Prefecture and Tazawa sample from Akita Prefecture in Japan), we investigated the radiation dose response of TL glow peaks separated using a glow curve fitting method. The radiation dose response of the separated peaks was examined using a growth curve based on the SAR TL protocol. The 260 °C, 290 °C and 320 °C peaks for the Yuda sample and the 270 °C and 320 °C peaks for the Tazawa sample showed a supralinear response up to 300 Gy, whereas the 370 °C peak for both samples behaved linearly.
