A level 2 on the INES is an Incident. A major Accident would be a level 7.

A level 2 is not that bad : 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.
