Abstract:
Method of determination of an irradiation dose deposited in a scintillator (5) by ionising radiation, comprising the steps of: irradiating the scintillator (5) during a predetermined time; detecting a moment of excitation of the scintillator (5) with a first photodetector (11); then detecting a moment of reception of a scintillation photon with a second photodetector (14), functioning in single photon counting mode; identifying each sequence consisting of the detection of a moment of excitation by the first photodetector (11), and the detection of a moment of reception by the second photodetector (14) with a coincidence event; counting the number of coincidence events; obtaining the irradiation dose deposited during the irradiation time as a function of the number of coincidence events counted and of a predetermined proportionality factor.
