How is unplanned radiation exposure defined?

• A. A radiation dose higher than what was expected for the job and area being worked
• B. A planned extra dose
• C. A dose below the expected range
• D. The routine exposure schedule

Answer: (A)

Unplanned exposure means a radiation dose that occurs outside what was expected for the specific job and area, typically a dose higher than what was anticipated. It signals that something went beyond the established plan and requires review to determine the cause and prevent recurrence. A planned extra dose is something that was anticipated and included in the work plan, so it isn’t unplanned. A dose below the expected range is underexposure, not unplanned exposure, and the routine exposure schedule is the normal, planned exposure.
