METHOD FOR CALIBRATION OF A GAMMA SPECTROMETER, ASSOCIATED CALIBRATION SYSTEM AND GAMMA SPECTROMETRY ASSEMBLY

摘要

The invention relates to a method for calibrating a gamma spectrometer (4) with a scintillator (8), the method comprising: - emission of UV radiation in the form of photon pulses, each photon having an energy greater than or equal at an ionization energy of the scintillator (8), the photon pulses being capable of generating, when received by the gamma spectrometer (4), a spectrum having at least one peak of interest at a corresponding reference energy; - from a scintillation current resulting from a detection of the photon pulses by the gamma spectrometer (4), calculation of a spectrum presenting each peak of interest at a measured energy; - for each peak of interest, comparison of the corresponding measured energy with the corresponding reference energy; and from the result of the comparison, determination of a gain (G) of the gamma spectrogram (4) to make correspond, for each peak of interest, the energy measured with the reference energy.
