Role of the Linear Accelerator (LINAC) in Security and Cargo Inspection – Part I

By:  Samy Hanna, PhD, PE. - Consultant Many ports around the world rely on X-ray scanners to inspect cargo for nuclear materials or weapons and prevent contraband from entering their countries. Conventionally, these have been gamma-ray scanners based on radioactive isotopes such as cobalt-60 or the common DC X-ray tubes. In spite of the recent advancement in X-ray tube technology, they are still ...
