ABSTRACT:

In the present study the effect of pre-irradiation deformation on the thermoluminescence (TL) of g-irradiated undoped and Cu++ doped NaCl crystals for different impurity concentrations, radiation doses etc. have been studied. Two peaks at 392? K and 465?K respectively are observed in TL glow curves of pre-irradiation deformed undoped and Cu++ doped NaCl crystals. The intensities of both the peaks in TL glow curves increases linearly with increasing pre-irradiation deformation of the pure and Cu++ doped NaCl crystals. It is found that increase in the TL peak-II with strain is higher as compared to that of TL peak-I. The temperature Tm1 and Tm2 corresponding to the first and second peaks in TL glow curves respectively, do not change significantly with the pre-irradiation deformation of the crystals.
