Customs lorry X-ray. Monitor view of a scanning X- ray of the rear end of a lorry made during a customs check. This X-ray was produced by a Sycoscan X-ray machine which scans large objects like vehicles, gradually producing a composite image of them. Any suspect areas can be magnified on the screen and then, if necessary, checked by hand. Photographed at Roissy/Charles de Gaulle Airport in Paris, France.
