Bibliographic information HMSO Books, PO Box 276, London SW8 5DT, United Kingdom, 1989. 30p. 32 ref. Price: GBP 4.00.
Abstract This paper examines ways in which risks can be assessed and the contribution such assessments make to decisions on the significance of risks for a particular situation. Topics covered include possible purposes of Quantified Risk Assessment (QRA), a general approach to risk regulation, quantification of the results of a major event expressed in terms of societal risk, and the extent and nature of risks and their effect upon prediction. Details are given of 16 cases in which a QRA was used in judging relative safety or applied to actual decisions. The varied nature of these analyses is examined together with decisions taken. It is concluded that there is no readily deductible and uniformly applicable upper level of acceptable societal risk. Although QRA contains some uncertainties, it should be a major component in risk decisions.
