Films moved rapidly can produce which artifact?

• A. Broken corners
• B. Yellow marks
• C. Heat burns
• D. Static marks

Answer: (D)

Static electricity on the film surface from rapid movement or friction can discharge and create static marks on the radiograph. These artifacts show up as black or gray, tree-like or branching patterns that don’t correspond to anatomy. They’re more likely in dry environments or when film is moved quickly, and they can be reduced by increasing humidity, using antistatic devices, and handling film more gently to minimize friction. Other issues like broken corners result from physical damage, yellow marks from chemical or aging problems, and heat burns from overheating during processing, which is why static marks are the best fit for rapid film movement.
