This publication describes a study of international, European and national legislation which protect the environment from radiation. Countries covered include Australia, Canada, France, Japan, the United Kingdom and the United States. The analysis of the legislation draws conclusions about how well the environment is protected from radiation, and identifies strengths and weaknesses of current approaches as well as trends in regulation. The book will be useful reading for regulators and policy makers in radiological protection, but also for those interested in environmental regulation more generally.
