Active Interrogation

  • Edward C. MorseEmail author
Part of the Advanced Sciences and Technologies for Security Applications book series (ASTSA)


Active interrogation is defined and general properties of active interrogation systems are described for various applications. Active interrogation with fast neutron sources are detailed, including differential die-away analysis, delayed neutrons from fission, and delayed gammas from fission. Next a treatment of neutron transport for fast neutrons is given, along with concepts from age theory and methods to treat hydrogenous media. Next photofission active interrogation is explored. Then nuclear resonance fluorescence (NRF) is studied from the nuclear physics involved, and from potential practical implementations. Photon sources for NRF are studied, including bremsstrahlung, laser Compton upshift, and laser wakefield acceleration combined with Compton upshift. Lastly, the health physics aspects applicable to these systems are presented, with some examples of radiation dose calculations for neutron-based and photon-based systems.
