Last trends in the development of halide scintillators

Halide scintillators are the most common used radiation detection materials but these scintillators are still under development. This presentation is devoted to scintillator developments for nuclear medicine (SPECT, PET, X-ray detectors, and so on) and high energy physics (BELLE and BaBar). Examples of recent detector design like calorimeters, curve, cylindrical and matrix detectors for nuclear medicine will be given. Some physical aspects of radiation damage suppression, afterglow decrease and energy storage will be discussed from the point of view of point defect manipulation. Harmful impurity classification is proposed for the specification of scintillators for new scientific experiments, medical and industrial applications. Particular attention is paid to the last years search of new efficient halide scintillation crystals. Some examples of emission modification are shown for ABX3 halide scintillators and dosimeters.
