Abstract
An improved way of using radiographic imagery to capture internal characteristics of a concrete structure, wherein radiographic film is placed on one side of the concrete structure and X-rays are transmitted towards the film from the other side. A target which is selectively radiographically impervious may be interposed to generate location or guidance indicia on the film. The target may itself be non-symmetric, such as being L-shaped, or alternatively or in addition, the location indicia may be non-symmetrically located on the target or alternatively, may be arrayed about the circumference of the target similar to numerals of a clock face. Imagery resulting from radiographic imagery may or may not display inclusions and other anomalies of the concrete structure.
