American Society for Nondestructive Testing (ASNT) Radiographic Testing Practice Test

Static marks are indeed a common indication of poor film handling during radiographic exposure. These marks occur when film is handled in such a way that static electricity builds up, leading to visible artifacts on the developed image. This issue can arise from a variety of factors including low humidity environments, certain types of film packaging, or improper handling techniques.

Static marks can significantly impact the quality of the radiographic image, making it difficult to interpret the results accurately. For instance, if a technician is not careful while handling multiple sheets of film, the friction can cause a discharge that leaves these unwanted marks, which can obscure details in the image.

The other options, while they may also be relevant in the context of film quality or handling issues, do not specifically address the artifacts caused by static electricity. Low image resolution might relate more to exposure settings or the quality of the radiographic equipment rather than handling. Films sticking together can be a result of humidity or poor storage conditions but do not inherently indicate film handling errors during exposure. Uneven film development relates to processing inconsistencies rather than handling errors prior to exposure.
