Abstract
The results are described of a study of three commercially available LiF:Mg,Cu,P TL materials aiming at using this phosphor for individual monitoring for weakly penetrating radiations. Due to the high radiation sensitivity of the material it is suitable for application as thin detectors which are necessary for monitoring weakly penetrating radiations. Furthermore, the good energy response characteristics of the material for exposure to photons makes it also attractive for monitoring strongly penetration radiations. Results are given on glow curve analyses of the LiF:Mg,Cu,P TL phosphor and data are presented on a number of important dosimetric characteristics of thin detectors prepared from the material, both commercially available detectors and samples prepared in the laboratory. In particular, annealing requirements, and response characteristics of the detectors to beta and photon radiation were studied.
