Which item is not part of the information shown on the radiograph?

• A. Date
• B. Owner's contact ID
• C. Radiographic ID number
• D. Material heat number

Answer: (D)

The item not shown on a radiograph is the material heat number. A radiograph label typically includes date, a unique radiographic ID number, and sometimes the owner's contact ID to ensure traceability and proper job linkage. The heat number, which identifies the specific batch/heat of steel from the mill, is part of material traceability records and quality documentation, not the radiograph image itself.
