The performance of IPs has not been studied at temperatures lower than 0$$^{circ}$$C. In the present study, an IP was irradiated with $$gamma$$ rays emitted from the mineral monazite at temperatures between -80 and 30$$^{circ}$$C to determine its fundamental properties. The IP response as a function of irradiation time was found to be linear, suggesting that the IP works properly at low temperatures. Fading, an effect which should be considered at temperatures of more than 0$$^{circ}$$C, was not observed at -30 and -80$$^{circ}$$C. Furthermore, the fading-corrected PSL value of the IP irradiated at -80$$^{circ}$$C was lower than at other temperatures (30, 5 and -30$$^{circ}$$C). This can be explained by TSL. Since the only intensive TSL peak in the temperature range from -80 to 30$$^{circ}$$C is present at about -43$$^{circ}$$C, some of the electrons trapped at F centers recombine with holes through the process of TSL before the stored radiation image is read out at room temperature.
