Book excerpt: Incidents in the past have made scientists aware of the need for accurate methods of radionuclide analyses in order to estimate the risk to the public from released radioactivity. This book is an authoritative, up-to-date collection of research contributions presented at the 12th International Symposium on Environmental Radiochemical Analysis. Representing the work of leading scientists from across the globe it presents information on radiochemical analysis, measurement of radioactivity, naturally occurring radioactive materials, radioactively contaminated land, fate of radionuclides in natural and engineered environments and behaviour and analysis of radionuclides in radioactive wastes. This essential work will be a key reference for graduates and professionals who work across fields involving analytical chemistry, environmental science and technology, and waste disposal.
