INES 2: Incident

Impact on People and Environment:
  • Exposure of a member of the public in excess of 10 mSv.
  • Exposure of a worker in excess of the statutory annual limits.
Impact on Radiological Barriers and Control:
  • Radiation levels in an operating area of more than 50 mSv/h.
  • Significant contamination within the facility into an area not expected by design.
Impact on Defence-in-Depth:
  • Significant failures in safety ­provisions but with no actual ­consequences.
  • Found highly radioactive sealed orphan source, device or transport package with safety provisions intact.
  • Inadequate packaging of a highly radioactive sealed source.
