The present invention relates to a gamma radiation detector probe with Geiger-Muller tube of the type which compensates for pulse losses of the Geiger-Muller tube due to dead time and linearizes its response to the number of pulses per unit of time in relation to the gamma radiation exposure rate, including a converter of the electric current from the Geiger tube into a current-dependent pulse frequency, an element for combining or mixing these pulses with those supplied by the Geiger tube, and logarithmic networks for adjusting the frequency of the converter in order to linearize the response of the complex.
