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.

Abstract: The invention relates to a novel discriminating molecule family for neutron and gamma radiation, and to the preparation method thereof. Said molecules are also useful for detecting radiation (X, gamma, electrons, protons, ions), and thus for manufacturing radar, and industrial or medical dosimetry instruments.
