FIELD: non-destructive testing. SUBSTANCE: several radiographic films are exposed simultaneously according to the method described. Intermediate screens are installed among the films. Total thickness of the screens corresponds to difference in thickness to be subjected to radiographic test for radiation attenuation. Defects are revealed at each film which are presented at specific depth range. Beam defects sizes are evaluated by means of standard plate which has grooves at bevelled edge of the plate. EFFECT: widened range of thicknesses of metal being subjected to radiographic test during single exposure. 3 dwg, 1 tbl
