    • The invention relates to a detector for the measurement of ionizing radiation, preferably γ-radiation and x-rays, comprising a scintillator and a light detector, the light detector being stabilized by using a predefined light source, preferably a Light Emitting Diode (LED), where the length and/or shape of the light pulses of the light source is different from the length and/or shape of the light pulses emitted by the scintillator. The light source induced pulses and the radiation induced pulses are separated from all other pulses on the basis of their pulse width. The detector is additionally stabilized by correcting the measured light output, that is the pulse height of the output signals, of the detector with the detector temperature shift, being dependant from the average pulse width of the accumulated γ-pulses.
