Agricultural Implications of the Fukushima Nuclear Accident (III)


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.

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.




Soils of Georgia


Book Description

This book describes a wide range of soils, from the humid subtropical coast of the Black Sea to the frozen peaks of the High Caucasus with more than 5.000 meters above sea level and from extremely humid areas in the West to dry, semi-desert regions in the East, with an enormous variety of rock parent materials, a very accentuated hydrology and a topography, ranging from large plains, hilly regions to steep and strongly dissected slopes and gorges in the High and Lower Caucasus. There is no other country in the world the size of Georgia with such a variety of soil forming conditions and soils. Therefore, V V Dokuchaev, one of the founders of the genetic soil classification, called Georgia an "Open-Air Museum of Soils". The book is subdivided into 6 chapters. In Chapter 1, the physiography of Georgia and the factors of soil formation such as topography, geology, climate and vegetation are described, followed by Chapter 2, with the detailed description of 21 soil groups, their morphological, physical and chemical characteristics, their many different subtypes and variations, and their ecology, based on 72 tables, 25 figures and 20 photos. Moreover, the location of each soil and its surface in % of the total surface of Georgia are explained, including the history of their discovery and investigation together with the relevant literature. In Chapter 3, the overall ecological conditions, especially problems of soil erosion by water and wind and the soil contamination by heavy metals and radionuclides are described, followed by Chapter 4 with an explanation of the soil use, based on physical and chemical soil characteristics. Two further chapters with references and soil photos conclude the book, which is written by Professor Tengiz F Urushadze from the Agricultural University of Georgia in Tbilisi and Professor Winfried E H Blum from the University of Natural Resources and Life Sciences (BOKU) in Vienna, Austria.




Radiation Dose Reconstruction for Epidemiologic Uses


Book Description

Growing public concern about releases of radiation into the environment has focused attention on the measurement of exposure of people living near nuclear weapons production facilities or in areas affected by accidental releases of radiation. Radiation-Dose Reconstruction for Epidemiologic Uses responds to the need for criteria for dose reconstruction studies, particularly if the doses are to be useful in epidemiology. This book provides specific and practical recommendations for whether, when, and how studies should be conducted, with an emphasis on public participation. Based on the expertise of scientists involved in dozens of dose reconstruction projects, this volume: Provides an overview of the basic requirements and technical aspects of dose reconstruction. Presents lessons to be learned from dose reconstructions after Chernobyl, Three Mile Island, and elsewhere. Explores the potential benefits and limitations of biological markers. Discusses how to establish the "source term"â€"that is, to determine what was released. Explores methods for identifying the environmental pathways by which radiation reaches the body. Offers details on three major categories of dose assessment.




Low-Dose Radiation Effects on Animals and Ecosystems


Book Description

This open access book summarizes the latest scientific findings regarding the biological effects of the Fukushima Daiichi Nuclear Power Plant (FNPP) accident in 2011. Various cases of changes in animals and organisms have been reported since the FNPP accident. However, it is often unknown whether they are actually due to radiation, since the dose or dose-rate are not necessarily associated with the changes observed. This book brings together the works of radiation biologists and ecologists to provide reliable radioecology data and gives insight into future radioprotection. The book examines the environmental pollution and radiation exposure, and contains valuable data from abandoned livestock in the ex-evacuation zone and from wild animals including invertebrates and vertebrates, aqueous and terrestrial animals, and plants that are subjected to long-term exposure in the area still affected by radiation. It also analyzes dose evaluation, and offers new perspectives gained from the accident, as well as an overview for future studies to promote radioprotection of humans and the ecosystem. Since the biological impact of radiation is influenced by various factors, it is difficult to scientifically define the effects of low-dose/low-dose-rate radiation. However, the detailed research data presented can be combined with the latest scientific and technological advances, such as artificial intelligence, to provide new insights in the future. This book is a unique and valuable resource for researchers, professionals and anyone interested in the impact of exposure to radiation or contamination with radioactive materials.

Radioactive Contamination of the Tokyo Metropolitan Area


Book Description

This book presents the 5-year monitoring of radioactive contamination in the Tokyo metropolitan area due to the Fukushima accident, covering radiation monitoring of soil, litter, river, water, seawater, aquatic sediments, fish and shellfish, and plants in urban areas. Based on spatial and temporal data, it evaluates the environmental radiation contamination of the Tokyo metropolitan following the first nuclear accident affecting an urban area since Chernobyl. Since little is known about the contamination in Kiev city, this data is particularly valuable, offering insights into the dynamics of radioactive contamination in metropolitan areas, which are of interest in relation to the behavior of radionuclides resulting not only from nuclear accidents but also from nuclear terrorism? As such, this book will be appeal to nuclear and radiation experts, environmental administration professionals and specialists in environmental protection groups, as well as student and academics in the related fields.
