✦ Synopsis
Based on a literature survey, solid materials of crystalline, amorphous, sintered and ceramic origin were selected and investigated for dosimetric applicability up to I00 MGy at irradiation temperatures up to 200°C. The thermal stability of the radiation induced centers was studied by post-irradiation annealing. Metrologically, electron spin resonance (ESR) spectroscopy, optical spectroscopy and thermoluminescence analysis were used. The results as achieved with the investigated detector materials are considered in view of practicability. Limitations due to center instability and saturation effects are reported.
