At what multiple of the intended exposure should overexposure be notified to the Health and Safety Executive (HSE)?

At what multiple of the intended exposure should overexposure be notified to the Health and Safety Executive (HSE)?

• A. Two times the intended exposure
• B. Five times the intended exposure
• C. Ten times the intended exposure
• D. Twenty times the intended exposure

Answer: (D)

Significant overexposure reporting thresholds are about when regulatory action is triggered for dosimetric misadministrations. In diagnostic radiography, a formal notification to the HSE is required only when the dose delivered is a large, unacceptable multiple of what was intended. The twentyfold threshold is used to flag truly major deviations that point to serious errors in technique, equipment, or process, prompting investigation and corrective action. In practice, you compare the actual dose delivered to the planned dose; if the actual is twenty times or more of the intended exposure, you must notify the HSE. For example, if the intended exposure was 1 unit, an actual exposure of 20 units or more would require notification. This high threshold keeps regulatory reporting focused on significant incidents while smaller variances are handled through internal records and quality assurance processes.
