Book Description
Most of the nuclear facilities built since the Second World War have ceased active operation and have been decommissioned. Some of the sites are heavily contaminated with radioactive substances. Correct and efficient action to mitigate the radiological consequences of such contamination will only be possible when the behaviour of radionuclides in the terrestrial environment is sufficiently well known. Yet radioecologists often find it difficult to study the transfer of radioactivity in agricultural land and semi-natural ecosystems, because of the complexity and diversity of such environments. The present book presents an analysis of all the factors that affect the behaviour of radionuclides as they move from their point of release through the environment and then enter the tissues of biota living in the ecosystems, in particular plants and animals consumed by humans. The course on which the book is based was held in a region that is heavily contaminated by radioactive discharges into the environment during nuclear weapons fabrication in the 1950s and '60s, and due to a severe accidental release following the explosion of a rad-waste tank in 1957. This allowed in situ training of the students. The book's main emphasis is on specific radioecological problems in severely contaminated areas in the former Soviet Union: the Southern Urals Trail, the rivers Techa-Isert-Tobol-Irtis-Ob, and the 30 km zone around Chernobyl. Systems examined include soils, arable and pasture land, forests, lakes and rivers. Special attention is paid to the effects of radiation on natural ecosystems: trees, soil-dwelling organisms, and aquatic organisms. Synergistic effects are also considered. Short, medium and long term countermeasures are discussed.

Book Description
This book provides extensive and comprehensive knowledge to the researchers/academics who are working in the field of cesium contaminated sites, and the impact on plants. This book is also helpful for graduate and undergraduate students who are specializing in radioecology or safe disposal of radioactive waste, remediation of legacies and the impact on the environment. Radiocesium (137Cs and 134Cs) was released into the environment as a result of nuclear weapons testing in 1950s and 1960s (~1x1018 Bq), and later due to the Chernobyl accident in 1986 (8.5x1016 Bq) and Fukushima Daiichi Nuclear Power Plant in 2011 (~1x1017 Bq). 137Cs is still of relevance due to its half-life of 30 years. The study of radioisotope 137Cs is important, as production and emission rates are high compared to other radioisotopes, due to high fission yield and high volatility. This book contains original work and reviews on how cesium is released into the environment on translocation from soil to plants and further on to animals and into the human food chain. Separate chapters focus on the effective half-life of cesium in plants and on how different cultivars are responding in accumulation of cesium. Other key chapters focus on cesium impact on single cells to higher plants and also on remediation measures as well as on basic mechanism used for remedial options and analysis of transfer factors. The book rounds off by contributions on cesium uptake and translocation and its toxicity in plants after the Chernobyl and Fukushima accidents.

Book Description
The classification of radioactive waste varies from state to state. This results in different management procedures for each country, while following IAEA and OECD/NEA recommendations. Radioactive waste comes from numerous sources. The largest volumes are generated by the decommissioning and dismantling of nuclear facilities. Long-lived, medium- and high-activity waste – categorized as the most hazardous types of waste – are in fact largely produced by nuclear power reactors, spent fuel reprocessing plants and nuclear accidents. Final disposal of very low-activity, low-activity and very short-lived waste is well controlled. However, final solutions for certain categories, including long-lived waste, sorted waste and spent graphite waste, are not yet in place. Management of Radioactive Waste reviews all the possible solutions and presents those chosen by the various states, including a chapter detailing policy on radioactive waste management, taking France as an example.

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.

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.
