The corrected amplitude calculation stage (AC(E)) includes a supplementary stage to subtract the escape contributor (X) from the energy channel (E+E1) for the measured amplitude (A(E). The energy (E1) being the escape energy associated with the probability ( alpha 1). Calculation is done iteratively channel by channel on N rays of the energy spectrum, in decreasing energy sense. Method of processing Gamma radiation energy spectrum, the energy spectrum includes at least a measured amplitude ray (A(E)) in an energy channel (E). The measured amplitude (A(E)) includes an escape contribution (X) associated with a escape probability ( alpha i). Has a stage for estimating the escape contribution (X) of the energy channel (E) by multiplying the measured amplitude (A(E)) by the escape probability ( alpha i) and a calculation stage for the corrected amplitude (AC(E)) of the energy channel (E) by adding the estimated escape contribution (X) ( alpha i /* A(E)) to the measured amplitude (A(E)). The energy spectrum includes N measured amplitude rays (A(En) (n-1; 2.; ..., N) forming the N components of a vector Vmes, and it includes an estimation stage of the escape contribution (X) of N rays in the form of an escape vector Vech = alpha i /* Vmes and a calculation stage of a corrected vector VA = Vmes + Vech. Calculation of a vector shift (Vdec) is included representing the group of shifted escape contributions for the escapee energy (E1) associated with the probability alpha i and the corrected vector calculation VB = VA - Vdec. |
