Analysis of gamma-ray nuclear resonant absorption (NRA) images for automatic explosives detection

A method developed for explosives detection via NRA image analysis is discussed. The results of processing simulated images, as well as experimental NRA-images are presented. The experimental images were obtained by scanning aviation cargo along with mock explosives provided by the US Federal Aviation Administration (FAA) using the NRA system developed at Soreq NRC. NRA is a novel transmission radiography technique that was originally developed at Soreq NRC for airline-baggage and cargo-container inspection.
