Radionuclide Behaviour in the Natural Environment

Radionuclide Behaviour in the Natural Environment PDF Author: Christophe Poinssot
Publisher: Elsevier
ISBN: 0857097199
Category : Technology & Engineering
Languages : en
Pages : 737

Book Description
Understanding radionuclide behaviour in the natural environment is essential to the sustainable development of the nuclear industry and key to assessing potential environmental risks reliably. Minimising those risks is essential to enhancing public confidence in nuclear technology. Scientific knowledge in this field has developed greatly over the last decade.Radionuclide behaviour in the natural environment provides a comprehensive overview of the key processes and parameters affecting radionuclide mobility and migration.After an introductory chapter, part one explores radionuclide chemistry in the natural environment, including aquatic chemistry and the impact of natural organic matter and microorganisms. Part two discusses the migration and radioecological behavior of radionuclides. Topics include hydrogeology, sorption and colloidal reactions as well as in-situ investigations. Principles of modelling coupled geochemical, transport and radioecological properties are also discussed. Part three covers application issues: assessment of radionuclide behaviour in contaminated sites, taking Chernobyl as an example, estimation of radiological exposure to the population, performance assessment considerations related to deep geological repositories, and remediation concepts for contaminated sites.With its distinguished editors and international team of expert contributors, Radionuclide behaviour in the natural environment is an essential tool for all those interested or involved in nuclear energy, from researchers, designers and industrial operators to environmental scientists. It also provides a comprehensive guide for academics of all levels in this field. - Provides a comprehensive overview of the key processes and parameters affecting radionuclide mobility and migration - Explores radionuclide chemistry in the natural environment - Discusses the migration and radioecological behaviour of radionuclides

Geochemical Prospecting for Thorium and Uranium Deposits

Geochemical Prospecting for Thorium and Uranium Deposits PDF Author: R.W. Boyle
Publisher: Elsevier
ISBN: 0444597638
Category : Technology & Engineering
Languages : en
Pages : 509

Book Description
Developments in Economic Geology, 16: Geochemical Prospecting for Thorium and Uranium Deposits focuses on the analysis of various geochemical methods applicable in the search for all types of thorium and uranium deposits. The publication first ponders on the general chemistry and geochemistry of thorium and uranium, deposits of thorium and uranium and their indicator elements, and geochemical prospecting for thorium and uranium. Discussions focus on radiation surveys, selection of areas, primary mineralization, supergene oxidation, and secondary enrichment of endogenic thorium and uranium deposits, and equilibrium in the natural radioactive series. The book then ponders on lithochemical, pedochemical, hydrochemical, and biogeochemical surveys of the geochemical prospecting for thorium and uranium. Topics include heavy and light mineral surveys of stream, river, pond, and lake sediments, detailed litochemical surveys utilizing primary halos, and case histories. The text takes a look at sampling procedures and analytical methods for estimating thorium and uranium and miscellaneous methods and atmochemical surveys on the geochemical prospecting for thorium and uranium, including isotopic methods, remote sensing and geothermal methods, and liquid inclusion and thermoluminescent methods. The book is a valuable source of data for researchers wanting to explore geochemical prospecting for thorium and uranium deposits.

Karst Bauxites

Karst Bauxites PDF Author: G. Bárdossy
Publisher: Elsevier
ISBN: 0444597530
Category : Nature
Languages : en
Pages : 450

Book Description
Karst Bauxites: Bauxite Deposits on Carbonate Rocks presents a comparison of bauxite regions using mathematical statistics methods. This book is divided into eight chapters that highlight the quantitative processing and assessment of the information available for bauxites. The opening chapters present observational and analytical evidence concerning karst bauxite, with particular emphasis on Hungarian bauxite deposits. The typical features of bauxites are analyzed from a variety of aspects and results from different bauxite regions are compared. Other chapters consider the feature of metamorphosed karst bauxites. The remaining chapters discuss the conditions of formation of karst bauxites and with the factors controlling their geographic and stratigraphic distribution. This book will prove useful to geologists, mineralogists, and researchers.

Uranium PDF Author: Peter C. Burns
Publisher: Walter de Gruyter GmbH & Co KG
ISBN: 1501509195
Category : Science
Languages : en
Pages : 696

Book Description
Volume 38 of Reviews in Mineralogy provides detailed reviews of various aspects of the mineralogy and geochemistry of uranium. We have attempted to produce a volume that incorporates most important aspects of uranium in natural systems, while providing some insight into important applications of uranium mineralogy and geochemistry to environmental problems. The result is a blend of perspectives and themes: historical (Chapter 1), crystal structures (Chapter 2), systematic mineralogy and paragenesis (Chapters 3 and 7), the genesis of uranium ore deposits (Chapters 4 and 6), the geochemical behavior of uranium and other actinides in natural fluids (Chapter 5), environmental aspects of uranium such as microbial effects, groundwater contamination and disposal of nuclear waste (Chapters 8, 9 and 10), and various analytical techniques applied to uranium-bearing phases (Chapters 11-14). This volume was written in preparation for a short course by the same title, sponsored by the Mineralogical Society of America, October 22 and 23, 1999 in Golden, Colorado, prior to MSA's joint annual meeting with the Geological Society of America.

Mineralogy of Uranium and Thorium

Mineralogy of Uranium and Thorium PDF Author: R. J. Lauf
Publisher:
ISBN: 9780764351136
Category : Mineralogy
Languages : en
Pages : 0

Book Description
"For students of geology, this book offers a systematic overview of uranium and thorium minerals, which are known for their intense ultraviolet fluorescence and are critically important as our source of nuclear energy. Learn about the geochemical conditions that produce significant ore deposits and view more than 600 maps, structure diagrams, color photos, and electron micrographs. A web link allows readers to view the more than 130 crystal structures in three dimensions for a richer appreciation of their details. The minerals are arranged to emphasize how they fit into chemical groups, and a thorough description is provided for each mineral. Major occurrences of interest to mineral collectors are arranged geographically, with maps showing the important deposits in uranium-producing countries. With the resurgence of interest in nuclear power, this book will be invaluable to mineral collectors and exploration geologists as well as to nuclear scientists and engineers interested in radioactive deposits."]c--Book jacket.
