  Abstract
  To perform the inspection of cargo containers a radioscopic screening is performed by switching between 6 and 9 MeV of boundary energies as rapidly as 200 times per second and measuring the penetration levels in the contents of cargo passing through the boards [1]. This technology facilitates the material identification via the analyses of the ratios of dual energy signals and the signal obtained at 6 and 9 MeV level. The techniques are developed for (a) visualizing the contents to produce an image suitable for a fast inspection by a human operator and for (b) prompting the custom personnel about the location and discrimination of suspicious objects. The experiments have been conducted with K9 device designed by Varian Medical Systems, Inc. The results show the capability of detecting suspicious objects through 10 inches of the steel shield. The developed tool secures the robust cargo inspection at the customs with a minimum involvement of the manual labor.
