Abstract
A method for measuring dosage by means of a radiation detector, especially an X-radiation or gamma-radiation detector, used in the spectroscopic mode, and a dosage measurement system using said method.A range of energies and a dose type H is chosen, a radiation detector of a given type is used, spectra measured by the detector are established for various radiations of the given type, the energies of which are within the chosen range and the respective doses of which are known, and from the spectra, a weighting function is established, that is a correspondence between a mean dose increment and a mean energy, deposited into the detector. This enables a person provided with a dosimeter identical to the detector to know at any time the mean absorbed dose rate, expressed in the amount H.
