Indices."Publisher Marketing: The book offers the opinions of experts regarding the interaction of radionuclides with the environment, and possible ways to immobilize and dispose of nuclear waste. The relevant areas span the spectrum from pure science, such as the fundamental physics and chemistry of the actinides, geology, environmental transport mechanisms, to engineering issues such as reactor operation and the design of nuclear waste repositories. The cross-fertilization between these various areas means that the material in the book should be accessible to seasoned scientists who may wish to obtain an overview of the state of the art in the field of environmental remediation of radionuclides, as well as to beginning scientists embarking on a career in this field.
