1. A method for measuring the activity of a radio-isotope, which method consists in placing said radio-isotope (3) in an ionization chamber (1) capable of providing a current proportional to the activity of said radio-isotope tested, then, using electronic means for processing the signal (15), in converting the value of the current into an activity value, by using a calibration coefficient corresponding to the radio-isotope at hand, characterised in that it consists:

  • in determining the energy spectrum of the radiation emitted by the radioisotope (3) placed in the ionisation chamber (1), in comparing automatically this energy spectrum with a set of energy spectra of pre-recorded or pre-programmed radio-isotopes, in order to identify the radio-isotope at hand, then in allocating automatically to the electronic means for processing the signal (15), the calibration coefficient corresponding to said radio-isotope at hand, to obtain the adequate activity measurement.
