What is the role of a radiographic film in gamma radiography?

The role of a radiographic film in gamma radiography is primarily to capture and record the radiation that passes through the object being examined. When gamma radiation interacts with the film, it causes a chemical change that results in the development of an image. This image provides critical information about the internal structure of the object, allowing for the identification of flaws, inconsistencies, or areas of interest that may not be visible from the outside.

In gamma radiography, the film serves as a medium to visualize the results of the radiography process. As the gamma rays penetrate the object, different materials absorb various amounts of radiation based on their density and composition. The film, after exposure, reveals these variations through differences in density, forming a clear representation of the internal features of the object.

Therefore, the key function of the radiographic film is its ability to record the gamma radiation exposure, enabling inspectors and technicians to analyze the resulting images for quality assurance and structural integrity assessments.
