Radiograph
A permanent image produced by transmission of penetrating radiation through an object onto film or a digital detector. Radiographs reveal internal structure, defects, and density variations. They are considered a definitive record of the inspection condition and are often retained for the life of a structure. Radiograph quality and proper interpretation are critical for reliable weld inspection and defect detection.
