Available in PDF, EPUB and Kindle. Book excerpt: The marine environment, in addition to a not insignificant background of “natural” radioactivity, has continued to receive inputs of radionuclides directly or indirectly through atomic fallout, discharges from the nuclear industry or from nuclear accidents. After their introduction, the fate of these radionuclides is complex with modifications of physicochemical forms, dispersion in marine water masses and adsorption onto sedimentary particles. Marine organisms then bioaccumulate these radionuclides to a greater or lesser extent, dispersing them via their burrowing activities, horizontal and vertical migrations or through food webs. All of these phenomena lead to very variable radioactive contamination, depending on location and the nature of the marine environments concerned, and consequently, to very different doses of irradiation to marine organisms. The harmful effects of ionizing radiation on living marine organisms are felt at varying levels of biological organization from the molecule to the ecosystem, passing through the cell, the organ, the individual and the population. In the end, the radioactive risk for marine organisms can decline according to several situations, which can be normal, programmed or accidental.

Book excerpt: Tropical Radioecology is a guide to the wide range of scientific practices and principles of this multidisciplinary field. It brings together past and present studies in the tropical and subtropical areas of the planet, highlighting the unique aspects of tropical systems. Until recently, radioecological models for tropical environments have depended upon data derived from temperate environments, despite the differences of these regions in terms of biota and abiotic conditions. Since radioactivity can be used to trace environmental processes in humans and other biota, this book offers examples of studies in which radiotracers have been used to assess biokinetics in tropical biota. This book: Features chapters co-authored by world experts that explain the origins, inputs, distributions, behaviour, and consequences of radioactivity in tropical and subtropical systems. Provides comprehensive lists of relevant data and identifies current knowledge gaps to allow for targeted radioecological research in the future. Integrates radioecological information into the most recent radiological consequences modelling and best-practice probabilistic ecological risk analysis methodology, given the need to understand the implications of enhanced socio-economic development in the world's tropical regions. John Twining has published research and conducted field and laboratory studies on the nuclear industry's impact on the environment over four decades. While much of this work has been related to Australia's role as a uranium supplier, he has also evaluated this impact at the Maralinga test sites in the deserts of central Australia and the effects of French testing in the central Pacific. John also focused on the uptake of radionuclides by crops and the use of isotopes as tracers of biological processes. Much of this work was accomplished in tropical or subtropical environments, and this experience proved valuable for Tropical Radioecology. John is now associate editor for the Journal of Environmental Radioecology and a self-employed consultant radioecologist.

This book was released on 2013-06-29 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: This reference explores oceanographic and biological conditions involved in the transfer and accumulation of radionuclides in marine sediment and biota of the Northern European seas. Much of the content synthesizes decades of work by the Murmansk Marine Biological Institute. This forms the basis of a new methodological and theoretical framework describing radionuclide bioaccumulation by marine invertebrate and vertebrate animals, with special attention to marine food webs leading to humans.

Available in PDF, EPUB and Kindle. Book excerpt: Considerable experience with radioecological and related ecological research on terrestrial and aquatic ecosystems has been achieved, especially after the Chernobyl accident. The combined effects of the radiation, chemical and biological factors, after a contamination of the environment and during its remediation have shown an interactive complexity that highlights the need for equidosimetrical evaluations of the influence of the various stressors and the need for their ecological normalization. In radioecology and radiation protection, methods of radiation dosimetry are key for dose assessment. It is therefore highly desirable to develop a clear theoretical approach as well as a practical method of equidosimetry that would allow for an ecological normalization of the different stressors in unified uniform units, especially for comparison purposes.

Available in PDF, EPUB and Kindle. Book excerpt: During the twenty years the authors have been associated with the field of radiation ecology, there has been a diversified and increasing use of radionuclides in applied and basic biological research. Prior to the advent of the atomic age in the 1940s the use of radionuclides as tracers was initiated, and following that period one observed a dramatically increased use in many disciplines. Concurrent with this increase there appeared many books and articles on radionuclide tech niques useful to biologists in general. Although only a few ecological applications were evident in these early years, ecologists were quick to see the opportunities available in their field. In the United States, major centers for such activities included Oak Ridge National Laboratory and the U. S. Atomic Energy Com mission's Savannah River Plant. At Oak Ridge National Laboratory Dr. Stanley I. Auerbach, director of ecological activities, encouraged with remarkable suc cess the use of tracers by his associates. Dr. Eugene P. Odum had the foresight to see that radionuclide tracers provided the means to solve many problems of interest to ecologists. Consequently, his research included some unique radio tracer applications at the Savannah River Plant. In addition he encouraged others involved in ecological activities at the Savannah River Plant to do likewise. Ecologists such as Dr. Robert C. Pendleton at the U. S. Atomic Energy Com mission's Hanford Works applied radionuclides in their research. To these early investigators and to those who followed we owe the oppportunity to write this book.
