When is the outline of the shim required on the radiograph?

• A. Always
• B. Only if applicable
• C. Never
• D. Only when used for calibration

Answer: (B)

In radiographic inspection, you only mark or show a shim on the film if that shim was used during the exposure. The outline serves as a reference, helping the reader see where the calibration or thickness step sits and how the film density relates to a known value. If no shim was used for that radiograph, there’s nothing to outline, so it isn’t required. So the outline should appear only when a shim is actually employed.
