Among the various TL dosemeters produced in this laboratory, LiF:Mg,Cu,P has turned out to be of special interest. The preparation and dosimetric characteristics of this new LiF dosemeter are reported and a description of the preparation method is presented. Its glow curve structure and TL response dependence with gamma exposure, re-usability, fading, sensitivity and energy dependence are studied along with those of LiF (TLD-100). The new LiF:Mg,Cu,P exhibits a dosimetric peak at 475 K. Its TL response is linear from 100 µGy. It is stable and re-usable without significant loss of sensitivity. Its sensitivity is about 25 times higher than that of commercial LiF (TLD-100) and its energy dependence similar. These and other characteristics render this dosemeter useful in diverse applications of radiation dosimetry.
