An exposure in any monitoring period that exceeds normal values is called what?

• A. Abnormal exposure
• B. IRSO
• C. All source total equivalent dose estimate
• D. Eye dose equivalent

Answer: (A)

When monitoring radiation, doses are compared to what’s normally expected during a given period. If the measurement in that period goes higher than those expected values, it’s described as an abnormal exposure. This flag signals that something out of the ordinary happened—perhaps an overexposure, a temporary spike in work activity, or a measurement/instrument issue—and it should prompt investigation and corrective action to determine the cause and prevent recurrence. Other terms like eye dose equivalent or cumulative dose estimates refer to specific metrics or calculations, not to a period-by-period exceedance of normal values, so they don’t fit this idea.
