Three thick single crystals grown at LIMHP were investigated in regard to their thermoluminescent and electric properties like glow curve, repeatability, linearity and the current under irradiation. The crystals A, B and C showed only a very short range of the linearity after irradiation with Cs‐137 and Co‐60 gamma rays. Next, the samples were investigated regarding to their electrical properties. The samples irradiated with a Co‐60 source presented a high sensitivity to the radiation but a long saturation time. The crystal A was irradiated using a special holder at the temperature of 250 °C. The current recorded was three times higher than that at room temperature and quickly saturated.
