A computerized glow curve analysis (GCA) method for WinREMS thermoluminescent dosimeter data using MATLAB

A computerized glow curve analysis (GCA) program for handling of thermoluminescence data originating from WinREMS is presented. The MATLAB program fits the glow peaks using the first-order kinetics model. Tested materials are LiF:Mg,Ti, CaF2:Dy, CaF2:Tm, CaF2:Mn, LiF:Mg,Cu,P, and CaSO4:Dy, with most having an average figure of merit (FOM) of 1.3% or less, with CaSO4:Dy 2.2% or less. Output is a list of fit parameters, peak areas, and graphs for each fit, evaluating each glow curve in 1.5 s or less.

► Robust algorithm for performing thermoluminescent dosimeter glow curve analysis.
► Written in MATLAB so readily implemented on variety of computers.
► Usage of figure of merit demonstrated for six different materials.
