Originally published in 1980. A clear understanding of how radioactivity moves through the environment is essential to discussions on nuclear power. This book describes, in didactic rather than polemic style, the nature of radioactivity, how it arises in the day-to-day running of nuclear reactors, how and why a small fraction is introduced into the environment in a controlled manner, and on what basis judgements on these processes should be made.

Natural radiation arises from many sources, from the unstable atoms within our own bodies and in the materials around us, from the Sun, and even from beyond the Solar System. Additional sources include the legacy of testing nuclear weapons, nuclear waste, and nuclear accidents. All these sources have provided means of dating environmental materials and tracing the movements of substances through land, sea, and air. But ionising radiation also interacts with DNA, which has led to a remarkable range of studies to examine how and how quickly these unstable atoms are accumulated by both humans and biota, and their various effects on both. Providing an overview of the sources, uses and impacts of ionising radiation in the environment, and the frameworks developed to manage exposures to them, this is a valuable reference for graduate students and researchers interested in radioecology, environmental science and radiological protection.
