Six TL glow-peaks at the temperatures 100, 150, 200, 275, 310 and 415/sup 0/C are observed in pure Al/sub 2/O/sub 3/ after gamma irradiation. For higher exposures (greater than 1000 R) the 275/sup 0/C TL glow-peak is masked by the lower temperature peaks and is not seen. Thermoluminescence of this pure Al/sub 2/O/sub 3/ is investigated after different thermal treatments. The overall sensitivity increases with annealing temperatures and reaches a maximum at about 1200/sup 0/C. The results are explained in terms of the structural change in alumina during these heat treatments.
