This book reevaluates the health risks of ionizing radiation in light of data that have become available since the 1980 report on this subject was published. The data include new, much more reliable dose estimates for the A-bomb survivors, the results of an additional 14 years of follow-up of the survivors for cancer mortality, recent results of follow-up studies of persons irradiated for medical purposes, and results of relevant experiments with laboratory animals and cultured cells. It analyzes the data in terms of risk estimates for specific organs in relation to dose and time after exposure, and compares radiation effects between Japanese and Western populations.

The Manhattan Project was the first real, large-scale, use of Nuclear materials. During the Manhattan project, radiation was not well understood and proper safeguards were not put in place yet. This work discusses radiation safety issues associated with the Manhattan Project and how the project began to establish safeguards for handling radiation. The role of key individuals in shaping policy is objectively demonstrated for both strategic defense as well as safety issues.

Yellow Dirt offers readers a window into a dark chapter of modern history that still reverberates today. From the 1940s into the early twenty-first century, the United States knowingly used and discarded an entire tribe for the sake of atomic bombs. Secretly, during the days of the Manhattan Project and then in a frenzy during the Cold War, the government bought up all the uranium that could be mined from the hundreds of rich deposits entombed under the sagebrush plains and sandstone cliffs. Despite warnings from physicians and scientists that long-term exposure could be harmful, even fatal, thousands of miners would work there unprotected. A second set of warnings emerged about the environmental impact. Yet even now, long after the uranium boom ended, and long after national security could be cited as a consideration, many residents are still surrounded by contaminated air, water, and soil. The radioactive 'yellow dirt' has ended up in their playgrounds, in their bread ovens, in their churches, and even in their garbage dumps. And they are still dying.

Four million tons of uranium ore were extracted from mines on the Navajo reservation primarily for developing the U.S. nuclear weapons stockpile. For over 30 years, the Navajo people have lived with the environmental and health effects of uranium contamination from this mining. In 2008, five federal agencies adopted a 5-year plan that identified targets for addressing contaminated abandoned mines, structures, water sources, former processing sites, and other sites. Federal agencies also provide funding to Navajo Nation agencies to assist with the cleanup work. This book examines the extent to which the agencies achieved the targets set in the 5-year plan and the reasons why or why not; what is known about the future scope of work, time frames, and costs; and any key challenges faced by the agencies in completing this work and any opportunities to overcome them.

Wastelanding tells the history of the uranium industry on Navajo land, asking why landscapes and the peoples who inhabit them are 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.
