METHOD FOR SELF-CALIBRATION OF A DEVICE FOR DETECTING IONISING RADIATION

Disclosed is a spectrometry method including: for at least one ionizing-radiation energy Ei, obtaining, for each energy Ei, a curve of the number of photons detected, during a measurement interval, as a function of time, by spectrometer; b) for each curve, computing a ratio of the number of photons...

Summary:Disclosed is a spectrometry method including: for at least one ionizing-radiation energy Ei, obtaining, for each energy Ei, a curve of the number of photons detected, during a measurement interval, as a function of time, by spectrometer; b) for each curve, computing a ratio of the number of photons detected defined and separate time periods to obtain, for each ionizing-radiation energy Ei, a number ai, or for each curve, acquiring one or more fitting parameters PAJi by making a fit to the corresponding curve with a fitting function; and comparing each number ai or each fitting parameter or set of fitting parameters PAJi with reference constants ai or, respectively, with reference fitting parameters PAJi associated with reference energies Ei to determine, for each number ai or each fitting parameter or set of fitting parameters PAJi, reference energy Ei of the ionizing radiation for which the corresponding curve was measured.
