Abstract

Current knowledge concerning the dosimetric characteristics of LiF:Mg,Cu,P and LiF:Mg,Ti is reviewed, including glow curve structure, response to annealing procedures, trap conversion processes, dose response, tissue-equivalence, residual signal and others. The relative merits of these two materials in various dosimetric applications; occupational exposure, clinical and environmental, as well as in mixed field beta/gamma and neutron/gamma dosimetry are evaluated and compared. LiF:Mg,Cu,P emerges as a very useful material with significant advantages over LiF:Mg,Ti in most dosimetric applications. However, it does share some of the faults of LiF:Mg,Ti mainly, complicated glow curve structure and thermal instability. Commercially available LiF:Mg,Cu,P (GR-200) is interior to LiF:Mg,Ti (TLD-100) in one important aspect - its relatively high residual signal. Future elimination/minimisation of the residual signal via materials research and/or readout/annealing procedures should lead to LiF;Mg,Cu,P totally replacing LiF:Mg,Ti.
