Interpretation of radiograph is the analysis of the shadow image formed on the film by radiation transmission pattern of the test specimen. The image is evaluated in terms of internal and external discontinuities of the specimen. Supporting information such as radiography test parameters, part geometry etc. and good knowledge about metallurgy, manufacturing process and flaw detection capability of radiographic technique is required for proper interpretation.

Competence in interpretation is acquired gradually by experience and critical analysis of the indications, sometimes supported by other NDT methods or metallographic. Though training cannot replace the experience but it can definitely act as catalyst and considerably accelerate the learning process
