Thermoluminescence trapping parameters of irradiated K-feldspar

Isothermal decay of the TL glow curve of the irradiated K-feldspars has been investigated at an ambient temperature. A suggested procedure enables the isolation of peaks at the low-temperature region of the TL glow curve. An analysis of the values of the symmetry factor suggests that bimolecular mechanisms are responsible for the kinetics of decay processes, as the values of parameter μ vary around 0.52. The values of the calculated activation energy do not show systematic correlation with the temperature at the investigated temperature region of the TL glow curve.
