Controversies about risks to public health regularly hit the news, whether about food safety, environmental issues, medical interventions, or lifestyle risks such as drinking. To those trying to manage or regulate risks, public reactions sometimes seem bizarre. To the public, the behaviour of those supposedly in charge can seem no less odd. Trust is currently at a premium. This volume brings together a wide variety of perspectives on risk communication, from the health professions, academia, campaigning organisations, government and its advisory committees, and independent consultancies and think tanks. It should be of interest not only to those involved in risk assessment or communication but to anyone interested in the role of science and the media in the political process, and how one bit of the system is responding to demands for greater openness and participation.
