The objective of this book is to present a comprehensive picture, first of the fundamentals of general contamination of solid surfaces and water, and in the second part, to review the main practical procedures and means of applied decontamination used in the fields of activity. The most emphasis on radioactive contamination deals with decontamination of the operational facilities in nuclear power plants. Other special decontamination branches of current interest are also dealt with briefly.The art of decontamination is being enriched by the progress achieved in relevant scientific disciplines and employs these relative advances. The current volume discusses in detail the following trends in Firstly, the development and use of new decontamination methods that are highly efficient, non-agressive to decontaminated materials, and economically feasible; secondly, the utilization of progressive elements of automation and robotics; thirdly, the development and use of such decontamination formulations that would minimize the volume of wastes and would produce wastes in a form in which they could be either easily further treated or safely disposed of without risk to human health or the environment; finally, the choice of suitable materials used both for the structural and the technological parts of nuclear installations with regard to their minimal contaminability and ease of decontamination.

Auf einer nächtlichen Bahnreise durch das winterliche Russland entspinnt sich zwischen wechselnden Fahrgästen ein langes Gespräch über Liebe, Ehe, Moral und Gesellschaft. Gegen Ende erzählt der ehemalige Gutsbesitzer Posdnyschew einem Mitreisenden vom tragischen Verlauf seiner Ehe und legt ein erschütterndes Geständnis ab: Zunehmend enttäuscht und von unbegründeter Eifersucht zerfressen hat er seiner Frau das Leben genommen. Meisterhaft setzt Leo Tolstoi die authentische Geschichte in Literatur um und entfaltet subtil das innere Drama seiner Figuren. Zugleich ist dieses bedeutende Alterswerk Ausdruck der eigenen sozialkritischen und moralischen Positionen.
