CRI Report Writing & Documentation 2 — Questions and Answers
Question 1: When documenting a linear indication in a weld radiograph, which measurement must always be included in the report?
- Depth of the indication
- Length of the indication (Correct answer)
- Width of the indication
- Volume of the indication
Correct answer: Length of the indication
Linear indications are characterized and reported by their length, as acceptance criteria in codes like ASME and AWS are length-based.
Question 2: A CRI report references 'IQI sensitivity achieved.' What does this statement confirm?
- The film density is within required limits
- The required image quality has been demonstrated on the radiograph (Correct answer)
- The radiation source was correctly selected
- The exposure time was properly calculated
Correct answer: The required image quality has been demonstrated on the radiograph
IQI (image quality indicator) sensitivity achieved means the required wire or hole is visible, confirming adequate radiographic technique and image quality.
Question 3: Which document section of a radiographic test report typically records the source-to-film distance (SFD)?
- Indication description
- Accept/reject summary
- Technique parameters (Correct answer)
- Personnel qualifications
Correct answer: Technique parameters
SFD is a technique parameter that affects geometric unsharpness and must be recorded in the technique section of the RT report.
Question 4: When a radiographic report must be revised after final sign-off, what is the correct documentation practice?
- Discard the original and issue a new report with the same number
- Cross out errors with a single line, initial, and date, then add the correction
- Use correction fluid to remove the error before correcting
- Issue a revised report with a new revision identifier and retain the original (Correct answer)
Correct answer: Issue a revised report with a new revision identifier and retain the original
Revisions require a new revision level (e.g., Rev. 1) while the original is retained, creating a complete audit trail per quality system requirements.
Question 5: In a radiographic report, what is the purpose of recording the 'object-to-film distance' (OFD)?
- To calculate the required film type
- To determine geometric unsharpness and magnification (Correct answer)
- To establish the minimum source strength needed
- To confirm the correct penetrameter was used
Correct answer: To determine geometric unsharpness and magnification
OFD is used in the geometric unsharpness formula (Ug = f × OFD/SFD) and affects image magnification, making it a critical documented parameter.
Question 6: A report states 'indication at 2-4T.' What does the 'T' reference indicate?
- The indication is located near the top surface of the material
- The indication location is expressed as a multiple of material thickness (Correct answer)
- The type of indication is a transverse crack
- The test was performed at 2 to 4 Tesla magnetic field strength
Correct answer: The indication location is expressed as a multiple of material thickness
In radiographic reports, 'T' denotes material thickness; '2-4T' means the indication is located between two and four times the material thickness from a reference datum.
Question 7: Which element is NOT typically required in the final sign-off section of an RT report per NDE Level III standards?
- Interpreter's certification level
- Interpreter's signature and date
- Customer's approval signature (Correct answer)
- Employer's name or stamp
Correct answer: Customer's approval signature
RT reports are certified by the qualified NDE interpreter; customer approval signatures are a contractual matter, not a standard NDE documentation requirement.
