Book Description
Just as an environmental model typically will be composed of a number of linked sub-models, representing physical, chemical or biological processes understood to varying degrees, this volume includes a series of linked chapters exemplifying the fundamental nature of environmental radioactivity models in all compartments of the environment. Why is a book on modelling environmental radioactivity necessary? There are many reasons why such a boook is necessary, perhaps the most important that: - modelling is an often misunderstood and maligned activity and this book can provide, to a broad audience, a greater understanding of modelling power but also some of the limitations. - modellers and experimentalists often do not understand and mistrust each other's work yet they are mutually dependent, in the sense that good experimental science can direct good modelling work and vice-versa; we hope that this book can dispel mistrust and engender improved understanding. - there is an increasing reliance on model results in environmental management, yet there is also often misuse and misrepresentation of these results. This book can help to bridge the gap between unrealistic expectations of model power and the realisation of what is possible, practicable and feasible in modelling of environmental radioactivity; and finally, - modelling tools, capacity and power have increased many-fold in a relatively short period of time. Much of this is due to the much-heralded computer revolution, but much is also due to better science. It is useful to consider what gap if any still remains between what is possible and what is necessary.

Book Description
After the Soviet Union's collapse, the newly independent nations that emerged from its wreckage were immediately confronted by a myriad of environmental problems, and continue to be plagued by them nearly a decade later. In a microcosm of the shortsighted planning, reckless development and lack of ecological concern that epitomized the Soviet era, 70 decommissioned nuclear submarines are currently moored in ports along the Kola Peninsula. Obsolete, damaged, or banned by strategic arms reductions treaties, they have been largely abandoned after being stripped of their offensive armament. Manned by skeleton crews, these toothless sharks hold within their poorly maintained hulls a total of nearly 30 times the amount of nuclear fuel that was in Chernobyl Reactor Number Four when it exploded in 1986. Reporters and ecologists (from Russia and elsewhere) have made a connection between that disaster and one they see unfolding in Russia's northwest, depicting the submarines as "floating Chernobyl" and "a Chernobyl in slow motion." This illustrates the irony of shifting perceptions in NATO countries about how these submarines threaten them. In their Cold War glory, these vessels were meticulously watched in the West. The threat they represented was defined in terms of the throw weights of the nuclear warheads they carried aboard. A decade after the Soviet implosion, these submarines are largely ignored. The threat they now pose is measured in metric tons of the spent fuel and radioactive waste carried within their decaying hulls.

Book Description
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.

Book Description
Shipping is responsible for transporting 90% of the world's trade. This book provides a comprehensive review of the impact shipping has on the environment. Topics covered include pollutant discharges such as atmospheric emissions, oil, chemical waste, sewage and biocides; as well as non-pollutant impacts including invasive species, wildlife collisions, noise, physical damage, and the environmental effects associated with shipwrecks and shipbreaking. The history of relevant international legislation is also covered. With chapters written by eminent international authors, this book provides a global perspective on the environmental impact of ships, making it a useful reference for advanced students and researchers of environmental science, as well as practitioners of maritime law and policy, and marine business.

Book Description
This book describes a new tool called the Generic Model System for simulations and assessment of potential radioactive spreading in the Arctic regions. It considers the present and future potential for spreading of radionuclear pollution from sources such as from the major Russian processing plants as well as from European sources such as the UK Sellafield plant. The book combines the expertise of professionals from the radionuclear and climate-change sciences.

Book Description
The goal of this book is to examine the complex state of radioactivity in the environment, and to understand the interplay of its two principal sources: man-made and natural. The text examines human contributions to release of radionuclides, with an eye to future reductions, and assesses natural occurrences in an evaluation of baseline radioactivity.
