Experimental research on detecting explosives with pulsed fast/thermal neutron analysis

In this article, the experimental research on the detection of explosives with pulsed fast/thermal neutron analysis is introduced. The elemental composition and contents of the tested materials can be determined by analyzing the characteristic gamma ray spectra. The explosives differ in the content and ratio of elements, such as H, C, O and N, from other non-explosives, which leads to their identification.
