摘要：

In this study, the preparation procedure and dosimetric characteristic of LiF activated by Mg, Cu and Ag were investigated for the first time. It was observed that with the thermal annealing at 240 degrees C for 10 min the sensitivity of the novel LiF: Mg, Cu, Ag powder was more than that of the TLD-100 powder. Also, the thermoluminescence intensity decreased with the increase of annealing temperature from 240 to 300 degrees C. The glow curve structure of this sample that is similar to TLD-100H shows a mean peak at similar to 243 degrees C along with four overlapping peaks. Also, the absorbed dose response increases linearly at low dose ranges. Other thermoluminescence characteristics of this phosphor such as low residual signal, low fading rate and good stability at repeatability and reusability make it useful for the dosimetric applications.
