A method for detecting a radioactive source moving on a linear path substantially parallel to an alignment of N detectors. The method includes: forming NxNt pulse counting values Mi,t (i=1, 2, . . . , N and t=1, 2, . . . , Nt) from NxNt detection signals delivered by the N detectors in the form of a succession over time of Nt sets of N signals simultaneously detected by the N detectors over a same duration Δt, a pulse counting value representing a number of pulses detected by a detector over a duration Δt; and computing, using a computer: a set of Nt correlation products Rt, a static mean R of the NxNt counting values, a correlation condition for each correlation product Rt. |
