Thermoluminescence (TL) of several types of corundum crystals is described. Undoped crystals showed a weak TL at 15 and 110°C with emission at 330 and 495 nm. Good TL response at 275°C is shown by Cr doped (0.03 wt%) crystals grown by Verneuil method in the oxygen cone of the flame annealed in hydrogen at 1500–1800°C. The most intensive TL response is shown by crystals doped with Ti and Mo (∼ 10 −3 wt.%) grown by Czochralski method in reducing conditions. The former may be used to the detection of γ‐rays dose ≥ 10 −3 − 10 −2 Gy, the latter ≥ 10 −7 − 10 −6 Gy.
