Radiographic Testing is a well-established NDT method that uses Gamma or X-rays to produce the image of a material onto a photographic film. Radiography provides quality, cost-effective, and permanent records with high volume capabilities due to simple operation and portability.

Applications include wall loss detection (profile radiography) and sizing in pipes and plates through to manufacturing defects in welds, forgings castings, etc.
Commonly used radioactive isotopes include Iridium 192, Cobalt 60, and Selenium 75.[
