U-M Nuclear Engineering and Radiological Science professor Igor Jovanovic discusses a new project in the realm of nuclear security. Special nuclear material (SNM), such as uranium or plutonium, is difficult to detect using the current methods of inspection with millions passing through each year. Jovanovic notes that a new technique, active interrogation, is more promising as the “suspicious material is irradiated by penetrating radiation.” Nuclear engineers want to combine this technique with an imaging technique to help detect specific materials inside containers,  explaining how these combined techniques will work in the field.
