<p>The invention concerns a method capable of discriminating between a gamma component and neutron component in an electronic signal (S1) resulting from the detection of gamma and/or neutron radiation, characterized in that it comprises the following steps: delaying by a time TAU and attenuating by a coefficient ALPHA the signal (S1), to obtain a delayed and attenuated signal (S2), subtracting the delayed and attenuated signal (S2) from the electronic signal (S1) to obtain a difference signal (S3) which comprises a gamma component and/or neutron component, and computing a magnitude sigma1 such that: sigma 1 =∫δT 2 S 3 ( t ) t whereδis an instant when the gamma component passes zero and T2 is a previously determined instant later than instantδchosen so that, in an interval [δref, T2], the magnitude sigma1 is negative for a gamma component and positive for a neutron component.</p> |
