What is a radiograph?

A radiograph is defined as the permanent record produced by radiographic testing. This image is created as a result of exposing a radiographic-sensitive film or digital detector to radiation as it passes through an object being tested. The radiograph serves to visualize internal structures, including flaws or discontinuities within materials, which is essential for quality assurance and compliance with safety standards in various industries.

Radiographs are crucial in the evaluation process because they provide an accurate and reliable way to document the findings of the inspection. Once produced, the radiograph can be archived, studied, and referenced for future assessments, which reinforces its role as a permanent record.

Other options do not accurately capture the definition of a radiograph. While temporary records, digital files, and summary reports may play a role in the broader context of radiographic testing, none of these represent the actual image produced during the inspection that is essential for evaluating the integrity of the material. Thus, the identification of a radiograph as the permanent image distinguishes it clearly within the radiographic testing process.
