Title
(EN) HAND-HELD PORTABLE BACKSCATTER INSPECTION SYSTEM
(FR) SYSTÈME D’INSPECTION PAR RÉTRODIFFUSION PORTABLE PORTATIF
Abstract
(EN)
The present specification describes a compact, hand-held probe or device that uses the principle of X-ray backscatter to provide immediate feedback to an operator about the presence of scattering and absorbing materials, items or objects behind concealing barriers irradiated by ionizing radiation, such as X-rays. Feedback is provided in the form of a changing audible tone whereby the pitch or frequency of the tone varies depending on the type of scattering material, item or object. Additionally or alternatively, the operator obtains a visual scan image on a screen by scanning the beam around a suspect area or anomaly.
(FR)
La présente invention concerne une sonde ou un dispositif portatif, compact qui utilise le principe de rétrodiffusion des rayons X pour fournir un retour immédiat à un opérateur concernant la présence de matériaux, articles ou objets diffuseurs et absorbeurs derrière des barrières de protection irradiées par un rayonnement ionisant, tel que des rayons X. Un retour est fourni sous la forme d'une tonalité sonore changeante de sorte que la hauteur ou la fréquence de la tonalité varie suivant le type de matériau, article ou objet diffuseur. De plus ou en variante, l'opérateur obtient une image de balayage visuel sur un écran par balayage du faisceau autour d'une zone suspecte ou anomalie.
