Abstract
The effect of gamma-radiation dose up to about 324 kGy on the thermolu minescence and dielectric properties of LiKSO4: Gd was studied. All gl ow curves exhibited a single peak around 373 K. The activation energy of this peak was estimated to be about 0.82 eV. The variation of the T L intensity with gamma-dose is characterized by a maximum at 6.75 kGy. The dielectric dispersion was studied as a function of irradiation do se. In the low frequency range straight line behaviour was obtained fo r low dose (up to 12.3 kGy) while for higher gamma-dose, semicircles a re obtained. The bulk conductivity was found to increase with dose up to 6.75 kGy.
