Overview of physical and biophysical techniques for accident dosimetry

Abstract

From feedback experience from recent radiation accident cases, in addition to biological dosimetry and physical dosimetry based on Monte Carlo calculations or experimental means, there is a need for complementary methods of dosimetry for radiation accident. Electron paramagnetic resonance (EPR) spectrometry on bones or teeth is considered as efficient but is limited by the invasive character of the sampling. Since 2005, Institute for Radiological Protection and Nuclear Safety (IRSN) develops some new approaches and methodologies based on the EPR and luminescence techniques. This article presents the overview of the different studies currently in progress in IRSN.
