Abstract

This paper describes the work performed to assess the effectiveness of scanners based on X-ray and gamma-ray transmission techniques for scanning cargo containers before entering different ports. Scanning by X-rays was done using X-ray machine operating at  135 KV and current of 4 mA. However, Scanning by gamma-rays was performed using collimated slit beam of 1 cm width and 5 cm height emitted from 0.5 Ci Cobalt-60 source. The transmitted gamma-rays through the container and the hidden object was measured by a gamma counting system applies NaI(Tl) detector. Objects of different physical and chemical composition were used in this study. The obtained images by X-ray transmission technique show incapability to distinguish between objects of nearly the same density. However the obtained images resulting from scanning by gamma-rays shows more capability to distinguish between all the examined objects.
