Reasonably Foreseeable

The term Reasonably Foreseeable is used in a number of areas of Radiation Protection, including Risk Assessment, Safety Cases and Probabilistic Safety Assessments (PSA). Reasonably foreseeable can be taken to mean an incident or accident which is thought to be Credible. It can be expressed numerically and this value will differ depending on the situation being assessed (but perhaps in the range of 10-5 to 10-6). The term does not appear to be defined exactly in legislation and there is certainly an interchange in interpretation with 'Credible'.

The definition of 'safe' is not strictly an engineering term; it's a societal term. Does it mean absolutely no loss of life? Does it mean absolutely no contamination with radiation? What exactly does 'safe' mean?
