Abstract

Method for examining the content of containers, which includes weighing the container, comparing the weight of the container with a total weight derived from the net weight of a given load and the product of the volume and the packing weight of the given load, transilluminating the container with a spatially limited high energy X-ray beam, moving the container relative to the X-ray, and determining and evaluating the distribution of the mass attenuation coefficient over at least one surface of the container, and an apparatus for carrying out the method.
