Book Description
To achieve successful solutions to the problems resulting from local, distant and global radioactive fallout after nuclear explosions and accidents and to achieve successful retrospective analyses of the radiation conditions from recent observations, certain information is needed: the distribution of the exposure dose rate in the atmosphere and in a country; the distribution of radionuclides in natural environments and the nuclide composition of the radioactive fallout; the features of formation of the aerosol particle-carriers of the radioactivity and of the nuclide distribution of the particles of different sizes formed under different conditions; the processes involved in the migration of radioactive products in different zones and environments; the external and internal effects of nuclear radiation on human beings.This monograph is devoted to a number of these problems, namely, to studies of the radioactive fallout composition, the formation of the aerosol particles that transport the radioactive products and to the analysis of the external radiation doses resulting from nuclear explosions and/or accidents. Problems of restoration and rehabilitation of contaminated land areas are also touched upon in the monograph. To solve such problems one requires knowledge of the mobility of radionuclides, an understanding of their uptake by plants, their transportation within the food chain and finally their uptake by animal and/or human organisms.The results of many years of study of radioactive fallout from atmospheric and underground nuclear explosions and accidents are summarized in this book. It is intended for various specialists - geophysicists, ecologists, health experts and inspectors, as well as those who are concerned with radioactive contamination of natural environments.

Book Description
Underground facilities are used extensively by many nations to conceal and protect strategic military functions and weapons' stockpiles. Because of their depth and hardened status, however, many of these strategic hard and deeply buried targets could only be put at risk by conventional or nuclear earth penetrating weapons (EPW). Recently, an engineering feasibility study, the robust nuclear earth penetrator program, was started by DOE and DOD to determine if a more effective EPW could be designed using major components of existing nuclear weapons. This activity has created some controversy about, among other things, the level of collateral damage that would ensue if such a weapon were used. To help clarify this issue, the Congress, in P.L. 107-314, directed the Secretary of Defense to request from the NRC a study of the anticipated health and environmental effects of nuclear earth-penetrators and other weapons and the effect of both conventional and nuclear weapons against the storage of biological and chemical weapons. This report provides the results of those analyses. Based on detailed numerical calculations, the report presents a series of findings comparing the effectiveness and expected collateral damage of nuclear EPW and surface nuclear weapons under a variety of conditions.

Book Description
The National Academies of Sciences, Engineering, and Medicine held a workshop on August 22â€"23, 2018, in Washington, DC, to explore medical and public health preparedness for a nuclear incident. The event brought together experts from government, nongovernmental organizations, academia, and the private sector to explore current assumptions behind the status of medical and public health preparedness for a nuclear incident, examine potential changes in these assumptions in light of increasing concerns about the use of nuclear warfare, and discuss challenges and opportunities for capacity building in the current threat environment. This publication summarizes the presentations and discussions from the workshop.

Book Description
Radioactive iodines are produced during the operation of nuclear power plants and during the detonation of nuclear weapons. In the event of a radiation incident, radioiodine is one of the contaminants that could be released into the environment. Exposure to radioiodine can lead to radiation injury to the thyroid, including thyroid cancer. Radiation to the thyroid from radioiodine can be limited by taking a nonradioactive iodine (stable iodine) such as potassium iodide. This book assesses strategies for the distribution and administration of potassium iodide (KI) in the event of a nuclear incident. The report says that potassium iodide pills should be available to everyone age 40 or youngerâ€"especially children and pregnant and lactating womenâ€"living near a nuclear power plant. States and municipalities should decide how to stockpile, distribute, and administer potassium iodide tablets, and federal agencies should keep a backup supply of tablets and be prepared to distribute them to affected areas.

Book Description
Do persons exposed to radiation suffer genetic effects that threaten their yet-to-be-born children? Researchers are concluding that the genetic risks of radiation are less than previously thought. This finding is explored in this volume about the children of atomic bomb survivors in Hiroshima and Nagasakiâ€"the population that can provide the greatest insight into this critical issue. Assembled here for the first time are papers representing more than 40 years of research. These documents reveal key results related to radiation's effects on pregnancy termination, sex ratio, congenital defects, and early mortality of children. Edited by two of the principal architects of the studies, J. V. Neel and W. J. Schull, the volume also offers an important comparison with studies of the genetic effects of radiation on mice. The wealth of technical details will be immediately useful to geneticists and other specialists. Policymakers will be interested in the overall conclusions and discussion of future studies.

Book Description
This open access book presents the findings from on-site research into radioactive cesium contamination in various agricultural systems affected by the Fukushima Daiichi Nuclear Power Plant accident in March 2011. This third volume in the series reports on studies undertaken at contaminated sites such as farmland, forests, and marine and freshwater environments, with a particular focus on livestock, wild plants and mushrooms, crops, and marine products in those environments. It also provides additional data collected in the subsequent years to show how the radioactivity levels in agricultural products and their growing environments have changed with time and the route by which radioactive materials entered agricultural products as well as their movement between different components (e.g., soil, water, and trees) within an environmental system (e.g., forests). The book covers various topics, including radioactivity testing of food products; decontamination trials for rice and livestock production; the state of contamination in, trees, mushrooms, and timber; the dynamics of radioactivity distribution in paddy fields and upland forests; damage incurred by the forestry and fishery industries; and the change in consumers’ attitudes. Chapter 19 introduces a real-time radioisotope imaging system, a pioneering technique to visualize the movement of cesium in soil and in plants. This is the only book to provide systematic data on the actual change of radioactivity, and as such is of great value to all researchers who wish to understand the effect of radioactive fallout on agriculture. In addition, it helps the general public to better understand the issues of radio-contamination in the environment. The project is ongoing; the research groups from the Graduate School of Agricultural and Life Sciences of The University of Tokyo continue their work in the field to further evaluate the long-term effects of the Fukushima accident.

Book Description
"Nuclear weapons, since their conception, have been the subject of secrecy. In the months after the dropping of the atomic bombs on Hiroshima and Nagasaki, the American scientific establishment, the American government, and the American public all wrestled with what was called the "problem of secrecy," wondering not only whether secrecy was appropriate and effective as a means of controlling this new technology but also whether it was compatible with the country's core values. Out of a messy context of propaganda, confusion, spy scares, and the grave counsel of competing groups of scientists, what historian Alex Wellerstein calls a "new regime of secrecy" was put into place. It was unlike any other previous or since. Nuclear secrets were given their own unique legal designation in American law ("restricted data"), one that operates differently than all other forms of national security classification and exists to this day. Drawing on massive amounts of declassified files, including records released by the government for the first time at the author's request, Restricted Data is a narrative account of nuclear secrecy and the tensions and uncertainty that built as the Cold War continued. In the US, both science and democracy are pitted against nuclear secrecy, and this makes its history uniquely compelling and timely"--

Book Description
An investigation into our complicated 8-decade-long relationship with nuclear technology, from the bomb to nuclear accidents to nuclear waste. From Hiroshima to Chernobyl, Fukushima to the growing legacy of lethal radioactive waste, humanity’s struggle to conquer atomic energy is rife with secrecy, deceit, human error, blatant disregard for life, short-sighted politics, and fear. Fallout is an eye-opening odyssey through the first eight decades of this struggle and the radioactive landscapes it has left behind. We are, he finds, forever torn between technological hubris and all-too-human terror about what we have created. At first, Pearce reminds us, America loved the bomb. Las Vegas, only seventy miles from the Nevada site of some hundred atmospheric tests, crowned four Miss Atomic Bombs in 1950s. Later, communities downwind of these tests suffered high cancer rates. The fate of a group of Japanese fishermen, who suffered high radiation doses from the first hydrogen bomb test in Bikini atoll, was worse. The United States Atomic Energy Commission accused them of being Red spies and ignored requests from the doctors desperately trying to treat them. Pearce moves on to explore the closed cities of the Soviet Union, where plutonium was refined and nuclear bombs tested throughout the ’50s and ’60s, and where the full extent of environmental and human damage is only now coming to light. Exploring the radioactive badlands created by nuclear accidents—not only the well-known examples of Chernobyl and Fukushima, but also the little known area around Satlykovo in the Russian Ural Mountains and the Windscale fire in the UK—Pearce describes the compulsive secrecy, deviousness, and lack of accountability that have persisted even as the technology has morphed from military to civilian uses. Finally, Pearce turns to the toxic legacies of nuclear technology: the emerging dilemmas over handling its waste and decommissioning of the great radioactive structures of the nuclear age, and the fearful doublethink over the world’s growing stockpiles of plutonium, the most lethal and ubiquitous product of nuclear technologies. For any reader who craves a clear-headed examination of the tangled relationship between a powerful technology and human politics, foibles, fears, and arrogance, Fallout is the definitive look at humanity’s nuclear adventure.
