Study on Differential Decay Analysis of Pulsed Neutron for Special Nuclear Material

摘要

In recent years,with the frequent occurrence of smuggling of nuclear materials and other radioactive materials,the governments of all countries strengthened the nuclear safety inspection efforts and inspection scope.Terrorists using their rough nuclear device(IND)to carry out low-power ground nuclear explosion will cause instantaneous compound damage and serious radioactive contamination,which are mainly caused by early nuclear radiation.The differential decay analysis of pulsed neutrons is studied by China Institute of Atomic Energy to detect nuclear materials.
