Abstract

Dispositif et procédé servant à cribler des objets inanimés dans le but de détecter des substances radioactives cachées. Ce dispositif et ce procédé mettent en application une combinaison d'au moins un détecteur à émissions gamma et la génération d'une image de transmission afin d'évaluer de façon non invasive le contenu d'un objet inanimé, tel qu'un réservoir, afin de déterminer la présence ou l'absence d'une substance radioactive. On peut utiliser une variété de configurations de détecteurs à émission gamma et de détecteurs de transmission afin de balayer rapidement les objets dans le but de rechercher la présence ou l'absence d'une substance radioactive.
