ABSTRACT:
It comprises an enclosure, a neutron emitting source (29) for bombarding said fissile material, means (28, 30) for introducing source (29) into the enclosure and for removing said source from the enclosure, neutron radiation detection means (9), moderator means (2, 4, 6) for thermalizing a fission radiation emitted by said fissile material interposed between the neutron radiation detection means (9) and the fissile material. It also has gamma radiation detection means (6, 14), which comprises a scintillator (6) and at least one photomultiplier (14) associated with said scintillator (6) and the scintillator material also constituting the moderator for thermalizing the fast neutrons directly emitted by the source (29), as well as the neutrons from the spontaneous fissions of the .alpha., n reaction and the neutrons from the fissions induced in the fissile material, the neutron radiation detectors (9) being embedded in the scintillator material (6) constituting the moderator.
