A method correcting a measured spectrum of X radiation, according to a number of channels Nc, each channel i corresponding to an energy range between Eand Ei+&#x394;E, including: determining function &#x3b4;t(k) determining size of temporal deviation &#x394;t interval separating two interactions with energy Eand E, stacking of which leads to a detected energy value E; determining, from the function &#x3b4;t(k), probability function P(k) that an event counted in a channel k corresponds to a stack of two interactions, respectively of energies Eand E; determining, from the probability function P(k), a stack spectrum as a part of the measured spectrum that corresponds only to the stacks alone; and calculating or estimating at least a first corrected spectrum, by the difference between the measured spectrum and the stack spectrum.
