What does a radiology badge indicate?

• A. Your department assignment.
• B. Your personal identification number.
• C. The amount of radiation you were exposed to.
• D. Your parking assignment.

Answer: (C)

A radiology badge is a dosimeter that records how much ionizing radiation you have been exposed to while working near X-ray equipment. Its primary purpose is safety: by accumulating your radiation dose over time, it helps ensure your exposure stays within regulatory limits and supports the ALARA principle (as low as reasonably achievable). The badge isn’t used to show where you park, your department assignment, or your personal ID number, and it doesn’t provide real-time dose readings on the spot; instead, it provides a recorded exposure that is read by radiation safety personnel to determine your total dose.
