1. A method for identifying one of a plurality of radiation detectors made of different materials having generated a first radiation representative signal in response to detection of a radiation, the plurality of radiation detectors being coupled to a data acquisition chain that acquires and processes first radiation representative signals generated by the plurality of radiation detectors in response to detection of a radiation, the detector identifying method comprising: defining a parameter vector including coefficients representative of at least one parameter common to the plurality of radiation detectors to characterize intrinsic properties of the different materials of the radiation detectors; modeling the data acquisition chain; for each radiation detector of the plurality of radiation detectors: submitting the radiation detector to a source of radiation such that the radiation detector generates a second radiation representative signal processed through the data acquisition chain; measuring the parameter vector specific to the radiation detector in response to the second radiation representative signal processed through the data acquisition chain taking into consideration the model of the acquisition chain; associating the specific parameter vector with the radiation detector; and measuring the parameter vector in response to the first radiation representative signal generated by said one radiation detector taking into consideration the model of the acquisition chain; whereby, in use, the said one radiation detector that has detected a radiation is identified by (a) comparing the parameter vector measured in response to the first radiation representative signal produced by said one radiation detector with the specific parameter vectors associated with the plurality of radiation detectors and (b) selecting the best match.
