Risk assessment: Choosing and managing technology-induced risk: How much risk should we choose to live with? How should we assess and manage the risks we face?

For pt.I see ibid., vol.18, no.11, p.58 (1981). This is the second of two articles on risk assessment. In the first, the author developed a framework for thinking about risk. In this framework, two processes-exposures and effects, at left in figure-act upon natural processes and human activities to produce some effect or change. The other two processes-perception and evaluation-act upon this change and develop some notion of risk through costs and benefits, and this is developed upon.
