Book Description
This report contains the first International Atomic Energy Agency projection of uranium supply and demand to 2050 and provides an understanding of how some alternative uranium supply scenarios could evolve over the period. The analysis is based on the current knowledge of uranium resources and production facilities, and takes into account the premise that they can operate with minimal environmental impact and employ the best practices in planning, operations, decommissioning and closure.

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.

Book Description
The book emphasizes various aspects of processing secondary sources for recovery of uranium. The field of secondary resource processing is gaining ground over the last few years as it is eco-friendly, economical and in tune with the philosophy of sustainable development. The book is the first one of its type in the area and includes a succint and comprehensive description of related areas of ore mineralogy, resource classification, processing principles involved in uranium solubilisation followed by separation and safety aspects. The clear organisation and the carefully selected figures and tables makes the treatment invaluable for practising engineers, research workers and academic institutions.

Book Description
Uranium mining in the Commonwealth of Virginia has been prohibited since 1982 by a state moratorium, although approval for restricted uranium exploration in the state was granted in 2007. Uranium Mining in Virginia examines the scientific, technical, environmental, human health and safety, and regulatory aspects of uranium mining, milling, and processing as they relate to the Commonwealth of Virginia for the purpose of assisting the Commonwealth to determine whether uranium mining, milling, and processing can be undertaken in a manner that safeguards the environment, natural and historic resources, agricultural lands, and the health and well-being of its citizens. According to this report, if Virginia lifts its moratorium, there are "steep hurdles to be surmounted" before mining and processing could take place within a regulatory setting that appropriately protects workers, the public, and the environment, especially given that the state has no experience regulating mining and processing of the radioactive element. The authoring committee was not asked to recommend whether uranium mining should be permitted, or to consider the potential benefits to the state were uranium mining to be pursued. It also was not asked to compare the relative risks of uranium mining to the mining of other fuels such as coal. This book will be of interest to decision makers at the state and local level, the energy industry, and concerned citizens.

Book Description
This book focuses on the engineering aspects of phosphorus (P) recovery and recycling, presenting recent research advances and applications of technologies in this important and challenging area of engineering. It highlights full-scale applications to illustrate the performance and effectiveness of the new technologies. As an essential element for all living organisms, P cannot be replaced by any other element in biochemical processes, humans ultimately rely its availability. Today, P is mostly obtained from mined rock phosphate (Pi). However, natural reserves of high-grade rock Pi are limited and dwindling on a global scale. As such, there have been increased efforts to recycle P from secondary sources, including sewage sludge, animal manure, food waste, and steelmaking slag, and so close the anthropogenic P cycle. In addition to various aspects of phosphorus covered by other literature, including chemistry, biochemistry, ecology, soil-plant systems and sustainable management, this book is a valuable and comprehensive source of information on the rapidly evolving field of P recovery and recycling engineering for students, researchers, and professionals responsible for sustainable use of phosphorus.

Book Description
Uranium is a naturally occurring, ubiquitous heavy metal. In various chemical forms, natural uranium is found in all soils, rocks, seas and oceans. It is also present in drinking water and food. Uranium was discovered in 1781 by Klaprot, a pharmacist in Berlin, in the Joachisthal silver mines. This book starts with a short history of uranium. It continues with the legacy of uranium mining and the authors go on to discuss the environmental and health effects of depleted uranium, which has the unique potential to threaten all natural resources, including human society because of its radiotoxic effects. Uranium migration properties are explored through the geological structures and the groundwater systems based on the determination of its total concentration essential for environmental studies. Other chapters examine the recovery of uranium from phosphate rock; the influence of uranium on the environment and the studies of content of uranium in soil, building materials, drinking water and even in the urine of specific population such as in the Czech Republic, a uranium rich territory; the types of uranium deposits; uranium bioremediation as an eco-friendly, promising approach, which will play an irreplaceable role in global nuclear energy development; discussions on uranium as one of the most widespread contaminants in groundwater in mining areas, as well as in surface waters in Brazil; and an examination of fuel materials that have been developed for use in nuclear power reactors including uranium. Bulk uranium-based systems are very complex and it is difficult to draw unambiguous conclusion on their properties and reaction mechanisms from experiments. Therefore in this book, laboratory experiments using simple model systems - thin films, for single effect studies which have a ground-breaking nature are explored in detail in this book.

Book Description
This report assesses the levels and effects of exposure to ionizing radiation. Scientific findings underpin radiation risk evaluation and international protection standards. This report comprises a report with two underpinning scientific annexes. The first annex recapitulates and clarifies the philosophy of science as well as the scientific knowledge for attributing observed health effects in individuals and populations to radiation exposure, and distinguishes between that and inferring risk to individuals and populations from an exposure. The second annex reviews the latest thinking and approaches to quantifying the uncertainties in assessments of risk from radiation exposure, and illustrates these approaches with application to examples that are highly pertinent to radiation protection.
