It is only with the ending of the Cold War that the issue of environmental hazards at many former nuclear testing sites around the world has attracted international scientific interest. This book discusses the environmental, ecological and health problems associated with nuclear testing. Topics treated include dose assessment, risk, speciation and transport of radionuclides, measurement and separation of radionuclides, and remedial options. The nuclear test sites examined include Semipalatinsk (Kazakhstan), Nevada (USA), the Pacific atolls and Maralinga (Australia). The volume also discusses the additional release sites of Chelyabinsk (Russia), Chernobyl (Ukraine), Palomares (Spain), Los Alamos (USA) and others. A compendium of radiological problems for a wide spectrum of readers, from non-specialist to expert.
