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 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.

Book Description
This book shares the latest insights into the genetic basis of molecular communication between plants and their microbial consortia. Further, the book highlights the capabilities of the rhizosphere and endosphere, which help manage ecosystem responses to climate change, nutrient cycling and sequestration of carbon; and discusses their application to the development and management of renewable energy sources. In their natural environments, plants are surrounded by a tremendous number of microorganisms. Some microbes directly interact with plants in a mutually beneficial fashion, while others colonize plants solely for their own advantage. In addition, microbes can indirectly affect plants by drastically altering their environments. Understanding the complex nature of the plant-microbe interface (PMI) can pave the way for novel strategies to improve plant productivity in an eco-friendly manner. The PMI approach focuses on understanding the physical, molecular, and chemical interactions between organisms in order to determine their functional roles in biological, physical, chemical and environmental systems. Although several metabolites from plants and microbes have now been fully characterized, their roles in chemical interactions between these associates remain poorly understood, and require further investigation.

Book Description
Accurate uranium analysis, and particularly for isotope measurements, is essential in many fields, including environmental studies, geology, hydrogeology, the nuclear industry, health physics, and homeland security. Nevertheless, only a few scientific books are dedicated to uranium in general and analytical chemistry aspects in particular. Analytical Chemistry of Uranium: Environmental, Forensic, Nuclear, and Toxicological Applications covers the fascinating advances in the field of analytical chemistry of uranium. Exploring a broad range of topics, the book focuses on the analytical aspects of industrial processes that involve uranium, its presence in the environment, health and biological implications of exposure to uranium compounds, and nuclear forensics. Topics include: Examples of procedures used to characterize uranium in environmental samples of soil, sediments, vegetation, water, and air Analytical methods used to examine the rigorous specifications of uranium and its compounds deployed in the nuclear fuel cycle Health aspects of exposure to uranium and the bioassays used for exposure assessment Up-to-date analytical techniques used in nuclear forensics for safeguards in support of non-proliferation, including single particle characterization Each chapter includes an overview of the topic and several examples to demonstrate the analytical procedures. This is followed by sample preparation, separation and purification techniques where necessary. The book supplies readers with a solid understanding of the analytical chemistry approach used today for characterizing the different facets of uranium, providing a good starting point for further investigation into this important element.

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
From 1978 to 1998, Uranium Mill Tailings Remedial Action (UMTRA) Project contractors removed and secured nearly forty million cubic yards of low-level radioactive uranium reduction mill tailings waste from abandoned mill sites in eleven states and four Indian reservations, enough material to bury 2300 football fields in ten feet of radioactive sand. The contractors also decontaminated over five thousand residential, commercial, and public properties that had been polluted with tailings. In addition to these federal efforts, the private uranium industry interred millions of tons of tailings generated by their mill operations. The UMTRA Project was the world??'s largest materials management program designed to shield the public from potentially hazardous radioactive materials. This is the story of that project, contextualized within the history of American atomic power and uranium mining. "Warm Sands" explores the structural factors that drove the formation of tailings policy, focusing on certain variables such as the legal centralization of authority over atomic energy in the federal government, the autonomy of the Atomic Energy Commission (AEC) and Congress??'s Joint Committee on Atomic Energy (JCAE), public health concerns, and traditional American democracy???vital to understanding the evolution of milling policy. Mogren discovered that non-elected governmental technocrats, scientists, lawyers, and administrators played a more influential role than did politicians or the public in the policy-making process. Furthermore, governmental organizations and semi-autonomous atomic bureaucrats did not function in predictable ways in the formation of mill tailings policy.
