Texas Industrial Radiography Gamma Practice Test

What non-destructive testing method utilizes penetrating radiation to detect flaws in components?

1. Detection Radiography

2. Mechanical Radiography

3. Image Testing

4. Industrial Radiography

The correct answer is: Industrial Radiography

Industrial Radiography is the non-destructive testing method that uses penetrating radiation, such as gamma rays or X-rays, to examine the internal structure of components and detect any flaws or defects. This technique is widely used in various industries for quality control, as it allows for an internal inspection without causing any damage to the item being tested. In Industrial Radiography, a radiation source is used to expose a film or digital detector positioned on the opposite side of the component being tested. The radiation penetrates through the component and creates an image that reveals variations in density and thickness, helping to identify cracks, inclusions, voids, or other irregularities within the material. This process is crucial for ensuring the integrity and safety of critical components, particularly in the aerospace, automotive, and construction industries. While other methods may involve different approaches or technologies for non-destructive testing, Industrial Radiography distinctly relies on the use of penetrating radiation to achieve its inspections.
