A cargo inspection apparatus and process includes scanning containers with x-rays along two different planes. Outputs from x-ray sensors along the two different planes are collected for use in establishing the presence of contraband within the container. Using the sensor output data, images of the container are provided and suspicious areas and background areas are identified on the images. By using representative suspicious area and background area geometry and compensating in the suspicious area for the effective estimated background thereat, the average atomic number and density of the suspicious contraband is established. The average atomic number and density is then compared with known atomic numbers and densities of contraband materials and an output indicative of whether the suspicious area falls within the parameters of actual contraband material is provided.
