Approaching an understanding of risk: a subject for the EFNDT working group 5 'NDT technology for public security and safety'

  • Safety and security both entail freedom from danger, i.e. unacceptable risk, whatever the cause might be. This entails an understanding of the term 'risk' that is broadly used in areas such as economics, health, insurance etc. According a rather popular definition used in the economical sciences for a long time (KNIGHT), risk has a lot in common with uncertainty while the former is regarded quantifiable and the latter one is not. However, it has to be taken into account that there are other understandings of 'uncertainty'. Particularly encountering rare events never experienced before and recent contemporary definitions are weakening Knightfs differentiation. This is reflected in some recent standard definitions. Attempts have been made to define a risk as common as possible covering not only societal, ecological and financial areas but also natural and technical, ones. This is of particular concern in non-destructive testing. This raises the question how far this can be achieved in aSafety and security both entail freedom from danger, i.e. unacceptable risk, whatever the cause might be.

This is of particular concern in non-destructive testing. This raises the question how far this can be achieved in a common understanding, i.e. the discussion on this term seems not at all finished yet. It is a common ambition to lower the risk by several actions including detection technologies. This entails that a risk could be estimated somehow. The existence of numerous approaches indicates the complexity of this question. The EFNDT (European Federation for Non-Destructive Testing) Working Group 5 took a commitment also to tackle this central aspect of safety and security in its understanding as a bridging forum between these two areas.zeige mehrzeige weniger
