Abstract
Abstract Lif:Mg, Cu, P polycrystal suffers a serious damage to its thermoluminescence (TL) sensitivity when exposed to high-level dose of 60Co gamma rays. After an exposure up to 106 Gy, the relative TL response of the peak (210°C) per unit absorbed dose is only 1.40 × 10−6 as compared with that exposed to low dose. While the residual peak is eliminated by annealing at 400°C, the thermoluminescent sensitivity is about 14% of the original one for a test dose of 0.01 Gy. High temperature annealing procedures have been investigated to remove the influence of radiation damage on its sensitivity at low dose. Results show that after annealing at 600°C for 30 min, the TL sensitivity of the samples exposed to high-level dose can be restored. The procedure of thermal treatment is described in detail. A possible explanation for the recovery is discussed.
