Under which conditions is a 24-hour notification to the Radiological Health Branch required?

• A. 1 and 2
• B. 1 and 3
• C. 2 and 3
• D. 1, 2, and 3

Answer: (D)

Timely reporting to the Radiological Health Branch is required whenever events or conditions have the potential to impact radiation safety or public health. A 24-hour notification ensures authorities are informed quickly so they can assess the situation, identify root causes, and take corrective actions to prevent recurrence. If each of the three conditions described in the item constitutes a reportable event, then any one of them triggers the 24-hour requirement. Including all three ensures every possible reportable scenario is covered, so the option that lists all three is the correct choice. This approach safeguards safety, maintains regulatory compliance, and supports prompt oversight and response.
