Which of the following can cause a radiograph to be rejected?

The option that indicates a cause for rejecting a radiograph focuses on the clarity and visibility of the weld image. In radiographic inspection, the quality of the image is paramount to accurately assess the integrity of the weld. An image with a light representation of a character, such as a "B," on a darker background may not provide sufficient contrast to clearly identify defects or inconsistencies in the weld. The lack of contrast makes it difficult for inspectors to analyze the radiograph properly, as critical details might become obscured, leading to misinterpretation of the weld’s quality.

In contrast, the absence of visible markings on the film indicates that the film has not been exposed correctly, which typically leads to rejection as well. However, if the film appears with a uniform density, it suggests that there are no variations that could indicate defects, which is generally acceptable in films that are not intended to reveal part details, unless other criteria apply. Similarly, a film that appears overly dark might be rejected due to the potential loss of detail, yet in some contexts, it can still provide contrast, although the risk of losing finer details is higher.

In summary, insufficient contrast, such as that seen with a light image of significant markers mixed with darker tones, plays a
