초록보기

In this paper, we used computerized glow curve deconvolution (CGCD) software with several models for the simulation of

a TL glow curve which was used for analysis. By using the general approximation plus model, parameters values of the

glow curve were analyzed and compared with the other models parameters (general approximation, mixed order kinetics,

general order kinetics). The LiF:Mg,Cu,Si and the LiF:Mg,Cu,P material were used for the glow curve analysis. And we

based on figure of merits (FOM) which was the goodness of the fitting that was monitored through the value between

analysis model and TLD materials. The ideal value of FOM is 0 which represents a perfect fit. The main glow peak makes

the most effect of radiation dose assessment of TLD materials. The main peak of the LiF:Mg,Cu,Si materials has a

intensity rate 80.76% of the whole TL glow intensity, and that of LiF:Mg,Cu,P materials has a intensity rate 68.07% of the

whole TL glow intensity. The activation energy of LiF:Mg,Cu,Si was analyzed as 2.39 eV by result of the general

approximation plus(GAP) model. In the case of mixed order kinetics (MOK), the activation energy was analyzed as 2.29

eV. The activation energy was analyzed as 2.38 eV by the general order kinetics (GOK) model. In the case of LiF:Mg,Cu,P

TLD, the activation energy was analyzed as 2.39 eV by result of the GAP model. In the case of MOK, the activation energy

was analyzed as 2.55 eV. The activation energy was analyzed as 2.51 eV by the GOK model. The R value means different

ratio of retrapping?recombination. The R value of LiF:Mg,Cu,Si TLD main peak analyzed as 1.12 x 10?6 and α value

analyzed as 1.0 x 10?3. The R of LiF:Mg,Cu,P TLD analyzed as 7.91 x 10?4, the α value means different ratio of initial

thermally trapped electron density?initial trapped electron density (include thermally disconnected trap electrons density).

The α value was analyzed as 9.17 x 10?1 which was the difference from LiF:Mg,Cu,Si TLD. The deep trap electron density

of LiF:Mg,Cu,Si was higher than the deep trap electron density of LiF:Mg,Cu,P.
