AbstractAbstract
[en] An activation neutron detector made as a moulded and cured composition of a material capable of being neutron-activated is described. The material is selected from a group consisting of at least two chemical elements, a compound of at least two chemical elements and their mixture, each of the chemical elements and their mixture, each of the chemical elements being capable of interacting with neutrons to form radioactive isotopes having different radiation energies when disintegrating. The material capable of being neutron-activated is distributed throughout the volume of a polycondensation resin inert with respect to neutrons and capable of curing. 17 Claims, No Drawings

AbstractAbstract
[en] The present invention concerns a neutron activation detector made from a moulded and hardened composition. According to the invention, that composition contains an activable substance constituted by at least two chemical elements and/or compounds of at least two chemical elements. Each of these chemical elements is capable of reacting with the neutrons forming radio-active isotopes with vatious levels of energy during desintegration. This neutron detector is mainly suitable for measuring integral thermal neutron and fast neutron fluxes during irradiation of the sample, and also for measuring the intensities of neutron fields

La presente invention concerne un detecteur a radio-activite pour neutrons qui est une composition moulee et durcie. Suivant l'invention, la composition contient une matiere activable constituee d'au moins deux elements chimiques. Chacun des elements chimiques est capable de reagir avec les neutrons formant des isotopes radioactifs qui presentent diverses energies d'emission au cours de la desintegration. On applique essentiellement le detecteur des neutrons propose pour mesurer les flux integraux de neutrons thermiques et rapides au cours de l'irradiation de l'echantillon ainsi que pour la mesure des intensites des champs neutroniquesOriginal Title

AbstractAbstract
[en] A detecting material capable of being activated by neutrons is mixed with a liquid polycondensation resin capable of thermal hardening. The obtained mixture is heated until the resin is transformed into a fusible product that is then cooled to room temperature. This hardened mixture is ground into powder suitable for pressing into tablets
