In June 1995, a campaign by Greenpeace forced the multinational oil company Shell to cancel its planned disposal of a redundant oil installation in the Atlantic. The Brent Spar incident attracted massive publicity and was influential in changing government policy on marine disposal of waste. During and following their campaign, Greenpeace were criticised as emotive and irrational by Shell and academic scientists. This paper looks at the arguments used during the debate, using literature, interviews and questionnaires. We investigate the use (...) of key environmental words and phrases and ask what is meant by rationality in this context. We discuss some of the lessons that should be learnt from the incident by policy makers and scientists. (shrink)

It seems likely that there is no threshold for the induction of cancer by ionising radiation. Hence even small radiation doses may result in a finite number of premature deaths if a large number of people are exposed. Various arguments are used to demonstrate that such deaths, if they occur, are acceptable; these arguments are shown to be flawed. Many of the arguments, and the ICRP's principle of justification, appear rooted in a utilitarian system of moral philosophy. Such a system (...) is superficially attractive as it appears objective and rational; however, the objectivity may be an illusion masking the underlying aims of the interested parties. (shrink)
