Figure 1. a) Dependence of intensity of RL spectra of GAAG:Ce on radiation dose; b) Area under the luminescence curve as a function of the dose of irradiation. The GAGG:Ce-based detectors have been therefore used for some in-vivo measurements. We found that the dose measured in the neck of the bladder (patients with inoperable cervical cancer) varied by 7%- 40% form the expected value (indicated by TPS). Figure 2 presents the dose distribution and the location of the measurent point.
