Environmental Radiochemical Analysis III

The Editor Peter Warwick, BA, MSc, PhD, FRSC, CCHem is Professor of Environmental Radiochemistry, Director of the Centre for Environmental Studies and Head of the Department of Chemistry at Loughborough University. Professor Warwick is a part Chairman of the Radiochemical Methods Group, Analytical Division, the Royal Society of Chemistry and was awarded the Becquerel Medal by them in 2002 for "outstanding contributions to radiochemistry". His major research interests are in the chemistry of nuclear active wastes disposal and in developing new methods of analyses for decommissioning wastes.
