Automated non-intrusive cargo inspection system using gamma-ray imaging (ROBOSCAN 1M)

摘要

Non-intrusive inspection of cargo containers has become a key issue in recent years to parry terrorist activities and to easily verify the shipping content at customs in order to avoid contraband. Such systems are mainly based on X- and gamma-ray radiography which offer inside images of the cargos. In this article we present a non-intrusive inspection system based on gamma-ray imaging called ROBOSCAN 1M. The system has a lower radiation field compared to existing X-ray systems, providing a smaller operational area and exclusion safety zone. It requires also less maintenance at a lower cost. It is also able to scan containers, vehicles, rail cars, while automatically detecting radioactive materials.
