What is the primary purpose of industrial radiography?

The primary purpose of industrial radiography is to inspect materials and structures for internal defects using radiation. This method involves the use of radiation, typically gamma rays or X-rays, to penetrate materials and reveal internal structures that may not be visible through standard visual inspection methods. By capturing the radiation that passes through the material onto a film or a digital detector, operators can create images that show any irregularities, such as cracks, voids, or inclusions, within the material.

This technique is essential in various industries, including construction, aerospace, and manufacturing, where the integrity and reliability of materials and components are critical. The ability to detect internal flaws ensures safety and compliance with industry standards.

The other options, while related to inspections and measurements, do not capture the essence of industrial radiography's primary purpose, which focuses specifically on revealing internal defects through the use of radiation.
