What type of exposure error is characterized by capturing two images on one film?

• A. Overexposure
• B. Underexposure
• C. Double exposure
• D. Motion blur

Answer: (C)

The phenomenon of capturing two images on one film is referred to as double exposure. This error occurs when a radiographic film is exposed multiple times without being properly processed in between exposures. As a result, the images overlap, leading to a confusing and often unusable final radiograph. Double exposure can occur due to operator error, such as forgetting to advance the film after the first exposure, or due to mechanical malfunctions in the imaging equipment. In this case, the correct identification of the exposure error as double exposure highlights the importance of careful operation and management of radiographic processes to ensure that each image is captured distinctly and accurately. Understanding this concept is crucial for radiologic technologists, as it directly impacts the quality and diagnostic value of the images they produce.
