Uranium in the Environment


Book Description

This book presents the results from the Uranium Mining and Hydrogeology Congress held in September 2005, in Freiberg, Germany. It addresses scientists and engineers involved in the areas of uranium mining and milling sites, clean-up measures, emissions of nuclear power plants and radioactive waste disposal, as well as political decision-makers. The topics covered are: impact on groundwater from radionuclide emission, analytical specification techniques, chemical toxicity, radioisotope plant uptake, microbiology, geochemical and reactive transport, case studies on active and abandoned uranium mines and milling sites, long-term storage of radioactive waste, passive in situ treatment techniques and risk assessment studies. The accompanying CD-ROM includes all papers in colour.




Uranium in Plants and the Environment


Book Description

In recent years, radioactive contamination in the environment by uranium (U) and its daughters has caused increasing concerns globally. This book provides recent developments and comprehensive knowledge to the researchers and academicians who are working on uranium contaminated areas worldwide. This book covers topics ranging from the beginning of the nuclear age until today, including historical views and epidemiological studies. Modelling practices and evaluation of radiological and chemical impact of uranium on man and the environment are included. Also covered are analytical methods used for the determination of uranium in geo/bio environments. Some chapters explore factors which influence uranium speciation and in consequence plant uptake/translocation. Last but not least, several chapters provide approaches and practices for remediation of uranium contaminated areas.




The Price of Nuclear Power


Book Description

Rising fossil fuel prices and concerns about greenhouse gas emissions are fostering a nuclear power renaissance and a revitalized uranium mining industry across the American West. In The Price of Nuclear Power, environmental sociologist Stephanie Malin offers an on-the-ground portrait of several uranium communities caught between the harmful legacy of previous mining booms and the potential promise of new economic development. Using this context, she examines how shifting notions of environmental justice inspire divergent views about nuclear power’s sustainability and equally divisive forms of social activism. Drawing on extensive fieldwork conducted in rural isolated towns such as Monticello, Utah, and Nucla and Naturita, Colorado, as well as in upscale communities like Telluride, Colorado, and incorporating interviews with community leaders, environmental activists, radiation regulators, and mining executives, Malin uncovers a fundamental paradox of the nuclear renaissance: the communities most hurt by uranium’s legacy—such as high rates of cancers, respiratory ailments, and reproductive disorders—were actually quick to support industry renewal. She shows that many impoverished communities support mining not only because of the employment opportunities, but also out of a personal identification with uranium, a sense of patriotism, and new notions of environmentalism. But other communities, such as Telluride, have become sites of resistance, skeptical of industry and government promises of safe mining, fearing that regulatory enforcement won’t be strong enough. Indeed, Malin shows that the nuclear renaissance has exacerbated social divisions across the Colorado Plateau, threatening social cohesion. Malin further illustrates ways in which renewed uranium production is not a socially sustainable form of energy development for rural communities, as it is utterly dependent on unstable global markets. The Price of Nuclear Power is an insightful portrait of the local impact of the nuclear renaissance and the social and environmental tensions inherent in the rebirth of uranium mining.




Radioactive Particles in the Environment


Book Description

Radioactive particles have been released to the environment from a number of sources, including nuclear weapon tests, nuclear accidents and discharges from nuclear installations. Particle characteristics influence the mobility, biological uptake and effects of radionuclides, hence information on these characteristics is essential for assessing environmental impact and risks. This publication presents a series of papers covering sources and source term characterisation, methodologies for characterizing particles, and the impact of particles on the behaviour of radioactive particles in the environment. Sources covered include the Chernobyl accident, nuclear weapons accidents at Thule and Palomares accident, the discharges from Dounreay and Krashnoyarsk, and depleted uranium in Kosovo and Kuwait. The overall aim is that an increased understanding of particle characteristics and behavior will help to reduce some of the uncertainties in environmental impact and risk assessment for particle contaminated areas.




The Navajo People and Uranium Mining


Book Description

Based on statements given to the Navajo Uranium Miner Oral History and Photography Project, this revealing book assesses the effects of uranium mining on the reservation beginning in the 1940s.




Wastelanding


Book Description

Wastelanding tells the history of the uranium industry on Navajo land in the U.S. Southwest, asking why certain landscapes and the peoples who inhabit them come to be targeted for disproportionate exposure to environmental harm. Uranium mines and mills on the Navajo Nation land have long supplied U.S. nuclear weapons and energy programs. By 1942, mines on the reservation were the main source of uranium for the top-secret Manhattan Project. Today, the Navajo Nation is home to more than a thousand abandoned uranium sites. Radiation-related diseases are endemic, claiming the health and lives of former miners and nonminers alike. Traci Brynne Voyles argues that the presence of uranium mining on Diné (Navajo) land constitutes a clear case of environmental racism. Looking at discursive constructions of landscapes, she explores how environmental racism develops over time. For Voyles, the “wasteland,” where toxic materials are excavated, exploited, and dumped, is both a racial and a spatial signifier that renders an environment and the bodies that inhabit it pollutable. Because environmental inequality is inherent in the way industrialism operates, the wasteland is the “other” through which modern industrialism is established. In examining the history of wastelanding in Navajo country, Voyles provides “an environmental justice history” of uranium mining, revealing how just as “civilization” has been defined on and through “savagery,” environmental privilege is produced by portraying other landscapes as marginal, worthless, and pollutable.




Chemical Separation Technologies and Related Methods of Nuclear Waste Management


Book Description

Separation technologies are of crucial importance to the goal of significantly reducing the volume of high-level nuclear waste, thereby reducing the long-term health risks to mankind. International co-operation, including the sharing of concepts and methods, as well as technology transfer, is essential in accelerating research and development in the field. The writers of this book are all internationally recognised experts in the field of separation technology, well qualified to assess and criticize the current state of separation research as well as to identify future opportunities for the application of separation technologies to the solution of nuclear waste management problems. The major emphases in the book are research opportunities in the utilization of innovative and potentially more efficient and cost effective processes for waste processing/treatment, actinide speciation/separation methods, technological processing, and environmental restoration.




Environmental Remediation and Restoration of Contaminated Nuclear and Norm Sites


Book Description

Nuclear sites become contaminated with radionuclides due to accidents and activities carried out without due consideration for the environment. Naturally-occurring radioactive materials (NORM) released by industrial processes such as coal power production and fertilizer manufacture may also require clean-up. Environmental remediation and restoration aim to reduce exposure to radiation from contaminated soil or groundwater. This book provides a comprehensive overview of this area. Part 1 provides an introduction to the different types of contaminated site and their characteristics. Part 2 addresses environmental restoration frameworks and processes. Part 3 then reviews different remediation techniques and methods of waste disposal. - Explores types and characteristics of contaminated nuclear and NORM sites - Provides an in depth guide to environmental restoration frameworks and processes including stakeholder involvement, risk assessment and cost-benefit analysis in the remediation and restoration of contaminated nuclear and NORM sites - Offers coverage of remediation techniques and waste disposal from electrokinetic remediation to in situ and ex situ bioremediation of radionuclides contaminated soils




Uranium


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.
