Signatures of fissile materials: high-energy g rays following fission

Abstract

The spectral and temporal dependence of b-delayed g rays in the range EX3:0 MeV from thermal–neutron-induced fission are shown to be characteristic signatures of U and Pu: For the interrogation of large sea-going cargo containers filled with hydrogenous materials, b-delayed g rays can offer an increase in sensitivity for the detection of these and other fissile materials by as much as 10–10 compared to the detection of b-delayed neutrons. r 2003 Elsevier B.V.
