Sample item

What is the SI unit of absorbed radiation dose?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

C. Gray

The central Radiation physics principle supports Gray; it is the answer that most directly explains the image finding, modality choice, or oral-health feature described.

Option by option

  • A. Pascal

    Pascal may be used elsewhere but is not the strongest answer here.

  • B. Tesla

    Tesla does not fit the stated radiation physics context.

  • C. Gray (correct)

    Correct. Gray best matches the key information in this scenario.

  • D. Joule per mole

    Joule per mole is not supported by the imaging or dental clue provided.
