ABSTRACT:
It comprises a first assembly (E1) constituted by a neutron radiation source (6), a hydrogenated material block (4) having a recess for receiving said source (6) and a first neutron detector (10); a second assembly (E2) constituted by a hydrogenated material block (14) surrounded by a material stopping the thermal neutrons (18) and a second neutron detector (16) placed in the hydrogenated material block (14); the first assembly (E1) and the second assembly (E2) being placed on either side of the area to be controlled (2). A foldback protective casket (8) can receive the neutron radiation source (6).
