The influence of irradiation temperature on the TL response of LiF : Mg,Cu,P

LiF:Mg,Cu,P is a relatively new and very promising thermoluminescent dosemeter for low dose measurements. The dose response in linear up to 10 Gy and then it becomes strongly sublinear. The glow curve remains unaltered up to 2500 Gy, while at even higher doses the high-temperature glow peak (270 degrees C) becomes prominent. The thermoluminescence response of coarse grains (80-140 mu m) does not depend on irradiation temperature (from 77-373 K) for doses 1-25 Gy. Similarly, the thermoluminescence response of the fine grains (1-8 mu m) is independent of irradiation temperature (293-373 K) for both beta and alpha irradiation.
