The general concern about the state of the environment has focused the attention of many countries in recent years on the need to remediate areas affected by radioactive residues. The present assessment was requested by the Government of the Republic of the Marshall Islands, with the purpose of obtaining an independent view of the radiological situation on Bikini Atoll, the site of nuclear weapons testing in the period 1946 -1958. In particular, questions were posed about whether the former inhabitants should be permitted to return to their homes and about the nature and extent of any remedial actions which might be necessary. This report presents the results and conclusions of a meeting of international experts convened by the IAEA and chaired by K. Lokan, Australia, in December 1995 to review the available information on the subject.
Coral reefs are the largest landforms built by plants and animals. Their study therefore incorporates a wide range of disciplines. This encyclopedia approaches coral reefs from an earth science perspective, concentrating especially on modern reefs. Currently coral reefs are under high stress, most prominently from climate change with changes to water temperature, sea level and ocean acidification particularly damaging. Modern reefs have evolved through the massive environmental changes of the Quaternary with long periods of exposure during glacially lowered sea level periods and short periods of interglacial growth. The entries in this encyclopedia condense the large amount of work carried out since Charles Darwin first attempted to understand reef evolution. Leading authorities from many countries have contributed to the entries covering areas of geology, geography and ecology, providing comprehensive access to the most up-to-date research on the structure, form and processes operating on Quaternary coral reefs.
“Engineering” has firmly taken root in the entangled bank of biology even as proposals to remake the living world have sent tendrils in every direction, and at every scale. Nature Remade explores these complex prospects from a resolutely historical approach, tracing cases across the decades of the long twentieth century. These essays span the many levels at which life has been engineered: molecule, cell, organism, population, ecosystem, and planet. From the cloning of agricultural crops and the artificial feeding of silkworms to biomimicry, genetic engineering, and terraforming, Nature Remade affirms the centrality of engineering in its various forms for understanding and imagining modern life. Organized around three themes—control and reproduction, knowing as making, and envisioning—the chapters in Nature Remade chart different means, scales, and consequences of intervening and reimagining nature.
Reports on the outcome of an IAEA coordinated research project in the area of measurement and characterization of radioactive particles in the environment. This publication summarizes the achievements and findings of the project participants and gives guidance for application of the techniques for evaluation of contaminated areas.
This book on Marine Radioactivity sets out to cover most of the aspects of marine radioactivity which have been the focus of scientific study in recent decades. The authors and their reviews divide into topic areas which have defined the field over its history. They cover the suite of natural radioisotopes which have been present in the oceans since their formation and quantitatively dominate the inventory of radioactivity in the oceans. Also addressed are the suite of artificial radionuclides introduced to the oceans as a consequence of the use of the atom for development of nuclear energy, nuclear weapons and various applications of nuclear science. The major source of these continues to derive from the global fallout of atmospheric tests of nuclear weapons in the 1950s and 1960s but also includes both planned and accidental releases of radioactivity from both civilian and military nuclear technology. The other division of the major study direction depends on whether the objective is to use the radionuclides as powerful tools to study oceanic processes, to describe and understand the ocean distribution of the various natural or artificial radionuclides or to assess the different radionuclides' impact on and pathways to man or marine organisms. The oceans cover 70% of the Earth's surface and thus contains a corresponding large share of the Earth's radioactivity. Marine Radioactivity covers topics of recent scientific study in this young field. It examines both natural radioactivity (radioactivity naturally present in oceans since their formation) and artificial radioactivity (radioactivity introduced by man and use of atomic and nuclear energy) with regard to possible effects on the global environment.
This case study describes the role an applied anthropologist takes to help Marshallese communities understand the impact of radiation exposure on the environment and themselves, and addresses problems stemming from the U.S. nuclear weapons testing program conducted in the Marshall Islands from 1946-1958. The author demonstrates how the U.S. Government limits its responsibilities for dealing with the problems it created in the Marshall Islands. Through archival, life history, and ethnographic research, the author constructs a compelling history of the testing program from a Marshallese perspective. For more than five decades, the Marshallese have experienced the effects of the weapons testing program on their health and their environment. This book amplifies the voice of the Marshallese who share their knowledge about illnesses, premature deaths, and exile from their homelands. The author uses linguistic analysis to show how the Marshallese developed a unique radiation language to discuss problems related to their radiation exposure problems that never existed before the testing program. Drawing on her own experiences working with the government of the Marshall Islands, the author emphasizes the role of an applied anthropologist in influencing policy, and empowering community leaders to seek meaningful remedies.
