Abstract

L'invention appartient au domaine de l'analyse des matériaux par rayonnement de neutrons et peut s'utiliser en premier lieu pour détecter des substances explosives contenant de l'azote dans les objets à contrôler sans les ouvrir. Selon l'invention, on irradie avec des neutrons thermiques une chambre équipée d'une protection contre les rayonnements et d'au moins un détecteur de rayons gamma; on enregistre le rayonnement gamma par la transformation des quanta gamma en impulsions électriques et par la comparaison de leurs amplitudes avec la valeur de seuil; on détermine le spectre énergétique des rayonnements gamma dans un intervalle d'énergie de quanta gamma, y compris une valeur de 2,23 MeV, et dans l'intervalle d'énergie de quanta gamma qui comprennent le seuil supérieur des valeurs d'énergie des quanta gamma émis pendant l'interaction avec les neutrons thermiques par les noyaux des atomes de l'élément chimique qui entre dans la composition des matériaux de la chambre, de la radioprotection ou du détecteur de rayons gamma; on détermine le point maximal et le point de chute du spectre énergétique dans les intervalles d'énergie indiqués, on détermine les amplitudes des impulsions électriques des quanta gamma avec des énergies qui correspondent à celles du point maximal et du point de chute; et l'on fait en sorte que ces amplitudes des impulsions électriques correspondent aux valeurs de calcul. Après cela on dispose l'objet à contrôler dans la chambre, on l'irradie avec des neutrons thermiques, on enregistre le rayonnement gamma dans l'intervalle d'énergie des quanta gamma comprenant la valeur de 2,23 MeV, on détermine le point maximal du spectre énergétique, on détermine l'amplitude des impulsions électriques provenant des quanta gamma avec une énergie qui correspond à l'énergie du point maximal, on détermine en tenant compte de l'amplitude indiquée les valeurs de seuil supérieure et inférieure pour l'émission d'impulsions électriques avec une amplitude proportionnelle à l'énergie des quanta gamma d'environ 10,8 MeV, on émet des impulsions électriques ayant une amplitude proportionnelle à l'énergie des quanta gamma d'environ 10,8 MeV par la comparaison de leurs amplitudes avec les valeurs de seuil supérieure et inférieure, on calcule les impulsions électriques émises et l'on tire une conclusion sur l'éventuelle présence d'un explosif dans l'objet contrôlé si les quantités mesurées dépassent une valeur de seuil. L'invention réduit les probabilités d'une fausse alerte ou de non-détection d'un explosif.
