Investigations on α-Al2O3 thermoluminescence for dosimetry of high energy photons.

This article presents a study of high-energy X-ray dosimetry carried out at CEA Gramat. In this study, we are interested in alumina as a new thermoluminescent dosimeter. We performed several pre-irradiation protocols to use alpha-alumina as a dosimeter over doses ranging from 0.09 Gy to 350/400 Gy in order to obtain calibration curve for these different protocols.
