FIELD: food industry. SUBSTANCE: method involves positioning focal spot of radiation source in the plane remote from can cover surface at a distance of h1=3-30 mm to enable one to take picture. Detector unit is placed outside of external side of seam. Focal distance is selected to be of the same order of value with ring-shaped joint diameter. The distance between the focal spot and detector is 1.5-3 times as large as the distance between the focal spot and the surface of the area under study. When taking picture, the radiation flow is directed at an angle of α1=1-45 deg to the cover surface. EFFECT: received full-scale seam image all over its height and in two projections; high accuracy of measurements. 2 cl, 5 dwg
