The two penetrameter types are wire type and plaque type. Which option reflects the two types?

• A. wire type and plaque type
• B. disk type and needle type
• C. block type and sheet type
• D. tube type and ring type

Answer: (A)

In radiographic testing, penetrameters (image quality indicators) come in two physical forms: wire type and plaque type. A wire-type penetrameter uses a fine wire as a reference element, creating a known density pattern on the film that helps assess image quality and penetration. A plaque-type penetrameter is a flat plate with predefined apertures or steps, producing a stepped density pattern on the radiograph to verify exposure and film response. Both forms serve the same purpose of providing a reliable standard for evaluating radiographic sensitivity and image quality, and the option that lists these two forms matches the established types.
