Abstract

Thermoluminescence (TL) spectra are complex curves that do not adhere the normal distribution but follow the first-, second-, general- order kinetics equations and require a software to analyze. This article presents a method of using R software to fit the empirical and the theoretical curves of the thermoluminescence glow peak types. Thank to this method, characteristic parameters of the trap are also defined such as number of peak, trap depth (E), the order of kinetic(b), the frequency factor (s). The samples spending shorter period of storage time (360h) have smaller kinetic parameter values than the samples spending longer period of storage (720h). Thereby, we can find out the characteristics of the samples which can be applied in the detection of irradiated food, age determination of antiques.
