Book Description
This comprehensive volume offers readers a progressive and highly detailed introduction to the complex behavior of neutrons in general, and in the context of nuclear power generation. A compendium and handbook for nuclear engineers, a source of teaching material for academic lecturers as well as a graduate text for advanced students and other non-experts wishing to enter this field, it is based on the author’s teaching and research experience and his recognized expertise in nuclear safety. After recapping a number of points in nuclear physics, placing the theoretical notions in their historical context, the book successively reveals the latest quantitative theories concerning: • The slowing-down of neutrons in matter • The charged particles and electromagnetic rays • The calculation scheme, especially the simplification hypothesis • The concept of criticality based on chain reactions • The theory of homogeneous and heterogeneous reactors • The problem of self-shielding • The theory of the nuclear reflector, a subject largely ignored in literature • The computational methods in transport and diffusion theories Complemented by more than 400 bibliographical references, some of which are commented and annotated, and augmented by an appendix on the history of reactor physics at EDF (Electricité De France), this book is the most comprehensive and up-to-date introduction to and reference resource in neutronics and reactor theory.

Book Description
Receptaculitids are extinct high-level fossils that provide a window into the history of life. After the discovery and analysis of a deposit of phosphatized receptaculitids on the Baltic Sea island of Öland, the authors conclude that receptaculitids possess an attribute not found in any other group of organisms, living or fossil.

Book Description
Radioecological Concentration Processes present the overall model for problems of environmental contamination in terms of system analysis. This book discusses the major investigational approaches to study of environmental contamination with radioactivity. Organized into 90 chapters, this book starts with an overview of the results of the experimental investigations into the distribution of strontium in soils and the uptake of this nuclide by plants. This text then presents the comparison of the distribution character in different soil types, which shows clearly that ploughed soils differ from virgin soils by a more uniform and similar character of radioisotope distribution in them. Other chapters consider the migration of 90Sr in the mostly podzolic and water-logged soils of moderately northern latitudes of Russia. The final chapter deals with the experiments with the shore crab Carcinus maenas, which shows that the crab is able to regulate the zinc content of its body against changes in the zinc content of food or of surrounding water. Biochemists will find this book useful.
