Abstract
A sample of silicate mineral considered as being jadeite but revealed to be more quartz-like, therefore named JQ2 has been studied concerning its TL and EPR properties. This study revealed a full correlation between the 210 °C TL peak and the g=2.0025 EPR signal. In both cases, the centers disappear at the same temperature and are restored after gamma irradiation. The TL peak at 210 °C may be related to the E'1 centers formed on irradiation. JQ2 responds to very high γ-dose and can be used as a high-dose dosimeter using TL and/or EPR techniques.
