In Wynnes contribution May the Sheep Safely Graze? to the book Risk, Environment and Modernity (1996), he elaborates on the responses of sheep farmers in Cumbria, who had been subjected to administrative restrictions due to radioactive contamination, allegedly caused by the nuclear accident at Chernobyl in 1986. The sheep farmers suffered economical losses, and it turned out that the source of radioactivity was actually the nuclear reprocessing complex Sellafield, thus the experts who were responsible for the duration of the restrictions, were mistaken. This particular case illustrates how the exercise of scientific interpretation controlled the farmers and furthermore how scientific knowledge neglects specialist lay knowledges, as it defines lay resistances as based on ignorance or irrationality. It also indicates the social basis of scientific knowledge and its public credibility. This is a development in the field of the Risk Society, as developed by Ulrich Beck and Anthony Giddens (Links needed).
