Sommario/riassunto |
|
Performance specifications and testing methods for the evaluation of handheld instruments (also known as radionuclide identification devices or RIDs) used for the detection and identification of radionuclides, which emit gamma rays and, in some cases, neutrons, are contained in this standard. The specifications for general, radiological, environmental, electromagnetic and mechanical performances are given and the corresponding testing methods are described. The documentation to be provided by the manufacturer is listed as part of the requirements. Normative and informative annexes that provide guidance for the implementation of this standard are also included. (The PDF of this standard is available at no cost compliments of the Department of Homeland Security Domestic Nuclear Detection Office. http://standards.ieee.org/getN42/download/N42.34-2015.pdf). Scope: This standard specifies general, radiological, environmental, electromagnetic, and mechanical requirements,and associated test methods for handheld radionuclide identification devices (RIDs). Successful completion of the tests described in this standard should not be construed as an ability to identify all radionuclides in all environments. Purpose: This standard addresses instruments that are used to detect and identify radionuclides, display gamma-ray exposure rates, and when provided, indicate the presence |
|
|
|
|
|
|
|
|
|
|
|
|
|
of neutron radiation. The identification requirements established by this standard are based on the sources and source configurations defined in this standard. When an RID is used operationally, the configuration of a source or object being analyzed is typically unknown, which may cause other radionuclides or isotopes to be identified. |

Sommario/riassunto |
|
Light pollution (light smog, light pollution or light emissions) is a fundamental problem in metropolises with effects on flora, fauna and people. Accordingly, the first section of the book discusses the basics of light pollution and its effects on various organisms. The characteristics of light smog in the cities of Hanover, Warsaw, Boston, New York City and Toronto are then analysed and compared. But how can the problem be tackled? Existing measures for the prevention of light pollution are discussed and further novel approaches are shown by comparing the metropolises. The book is aimed primarily at practitioners in this field and helps to identify sources of emissions and identify suitable reduction measures. The Content What is light pollution ? Effects of artificial light after dark International comparative analysis Simulation of urban scenarios and spaces Interdisciplinary solutions for reducing urban light pollution The Target Groups City and regional planners, architects, civil engineers, urbanists, light planners, biologists Lecturers and teachers in urban and spatial planning training courses About the Author Emlyn Etienne Goronczy holds an academic degree in architecture with a focus on lighting design. He works in an international planning office and was awarded the Fritz-Schumacher-Preis of the City of Hamburg in the junior category. This book is a translation of the original German edition „Lichtverschmutzung in Metropolen“ by Emlyn Etienne Goronczy, published by Springer Fachmedien Wiesbaden GmbH in 2018. The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). A subsequent human revision was done primarily in terms of content, so that the book will read stylistically differently from a conventional translation. Springer Nature works continuously to further the development of tools for the production of books and on the related technologies to support the authors. |
