Dosimetry Group of the Paul Scherrer Institute
Research interestsThe Dosimetry Group of the Paul Scherrer Institute carries out research on topics of interest for radiation dosimetry in general. Current research interests include:
• Luminescence processes in insulators: fundamental of luminescence properties in storage phosphors, scintillators, persistent phosphors; recombination process; stimulated luminescence phenomena.
• Radiation dosimetry: solid-state luminescence dosimetry; radiation effects in insulators; thermoluminescence (TL) and optically stimulated luminescence (OSL); modeling of TL and OSL processes in dosimetric materials; neutron dosimetry using plastic nuclear track detectors and fluorescence nuclear track detectors (FNTDs).
• Medical dosimetry: development of methodology for dose verification in radiotherapy, particularly small field dosimetry and 2D dose mapping, of high energy photons, protons and heavy-charged particles; new technologies for dose verification in Computed Tomography; Monte-Carlo simulations of dose deposition in detectors; out-of-field measurements in radiation therapy.
• Space dosimetry: characterization of TL and OSL dosimeters for use in the space radiation field; development of methodologies for analysis of TL/OSL data in complex radiation fields; modeling of the microdosimetric distribution created by heavy-charged-particles in TL/OSL materials.
• Retrospective and accident dosimetry: investigation of materials and methods to provide retrospective information in case of accidents involving radiation; application of the OSL technique for triage in case of radiological/nuclear accidents.
