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

ABSTRACT

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 LiFMg,Ti, CaF(2)Dy, CaF(2)Tm, CaF(2)Mn, LiFMg,Cu,P, and CaSO(4)Dy, with most having an average figure of merit (FOM) of 1.3% or less, with CaSO(4)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.
