Radiographic testing is one of the most widely used techniques in the field of non-destructive testing (NDT) to detect internal discontinuities without altering the integrity of the material. Its physical principle, based on the differential attenuation of radiation as it passes through solids, reveals defects with high precision.<\/p>\n\n\n\n

Today, with the advent of industrial digital radiography, computed radiography (CR) and direct radiography (DR) systems have progressively replaced traditional films, offering instant imaging, digital traceability (DICONDE) and reduced radiological exposure. This breakthrough marks a turning point in the modern inspection and quality control industry.<\/p>\n\n\n\n

Fundamentals of radiographic testing<\/h2>\n\n\n\n

Radiographic testing uses ionizing radiation (X-rays or gamma rays) to examine the internal structure of a component.<\/p>\n\n\n\n

When a beam of radiation passes through a material, its intensity decreases according to the law of exponential attenuation, which depends on the density, thickness and composition of the object. A discontinuity, such as cracks, porosity or inclusions<\/a><\/strong>, alters this behavior, generating a visible contrast in the image.<\/p>\n\n\n\n
