Download or read book Nuclear Non proliferation and Arms Control Verification written by Irmgard Niemeyer and published by Springer Nature. This book was released on 2020-03-12 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book strives to take stock of current achievements and existing challenges in nuclear verification, identify the available information and gaps that can act as drivers for exploring new approaches to verification strategies and technologies. With the practical application of the systems concept to nuclear disarmament scenarios and other, non-nuclear verification fields, it investigates, where greater transparency and confidence could be achieved in pursuit of new national or international nonproliferation and arms reduction efforts. A final discussion looks at how, in the absence of formal government-to-government negotiations, experts can take practical steps to advance the technical development of these concepts.

Download or read book NUSIMEP 6 Uranium Isotope Amount Ratios in Uranium Particles written by and published by . This book was released on 2008 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Additional Protocol (AP) authorizes safeguards authorities to verify the absence of undeclared nuclear activities in all parts of a state's nuclear fuel cycle as well as any other location where nuclear material is or may be present. As part of the Additional Protocol, environmental sampling has become an important tool for the detection of non-declared nuclear activities. In environmental sampling micrometer-sized uranium particles with an isotopic composition characteristic for the processes at the inspected facility need to be collected, identified and analysed. Considering the potential consequences of the analyses, these measurements need to be subjected to a rigorous quality management system. NUSIMEP-6 focused on measurements of Uranium isotope amount ratios in uranium particles aiming to support laboratories involved in uranium particle analysis. It was the first NUSIMEP on particle analysis coordinated by IRMM and was also intended as a pilot interlaboratory comparison in this field to gather feedback towards future optimisation and improvements. NUSIMEP-6 was open for participation to all laboratories in the field of particle analysis, particularly also to the IAEA network of analytical laboratories for environmental sampling (NWAL). The NUSIMEP test samples were prepared by controlled hydrolysis of well certified uranium hexafluoride close to natural uranium isotopic composition. Participating laboratories in NUSIMEP-6 received a test sample of uranium particles on a graphite planchet with undisclosed isotope amount ratio values n(234U)/n(238U), n(235U)/n(238U) and n(236U)/n(238U). The uranium isotope amount ratios were to be measured using their routine analytical procedures. Measurement of the major ratio n(235U)/n(238U) was obligatory; measurements of the minor ratios n(234U)/n(238U) and n(236U)/n(238U) were optional. 15 institutes reported measurement results using different analytical methods, among those 7 NWAL laboratories. The participants' measurement results were evaluated against the certified reference values. In addition, zeta scores were calculated. The results of NUSIMEP-6 confirm the capability of laboratories in measuring the ratio n(235U)/n(238U) and n(234U)/n(238U) in uranium particles. Difficulties were particularly observed for the ratio n(236U)/n(238U). In addition feedback from the participants was collected in view of improvements and optimisation of future NUSIMEP interlaboratory comparisons for uranium isotope amount ratios in uranium particles.

Download or read book PET Chemistry written by P.A. Schubiger and published by Springer Science & Business Media. This book was released on 2007-01-19 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Personalized medicine employing patient-based tailor-made therapeutic drugs is taking over treatment paradigms in a variety of ?elds in oncology and the central nervous system. The success of such therapies is mainly dependent on ef?cacious therapeutic drugs and a selective imaging probe for identi?cation of potential responders as well as therapy monitoring for an early bene?t assessment. Molecular imaging (MI) is based on the selective and speci?c interaction of a molecular probe with a biological target which is visualized through nuclear, magnetic resonance, near infrared or other methods. Therefore it is the method of choice for patient selection and therapy monitoring as well as for speci?c e- point monitoring in modern drug development. PET (positron emitting tomography), a nuclear medical imaging modality, is ideally suited to produce three-dimensional images of various targets or processes. The rapidly increasing demand for highly selective probes for MI strongly pushes the development of new PET tracers and PET chemistry. ‘PET chemistry’ can be de?ned as the study of positron-emitting compounds regarding their synthesis, structure, composition, reactivity, nuclear properties and processes and their properties in natural and - natural environments. In practice PET chemistry is strongly in?uenced by the unique properties of the radioisotopes used (e. g. , half-life, che- cal reactivity, etc. ) and integrates scienti?c aspects of nuclear-, organic-, inorganic- and biochemistry.

Download or read book Radionuclides in the Environment written by David A. Atwood and published by John Wiley & Sons. This book was released on 2013-02-19 with total page 546 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nuclear energy is the one energy source that could meet the world's growing energy needs and provide a smooth transition from fossil fuels to renewable energy in the coming decades and centuries. It is becoming abundantly clear that an increase in nuclear energy capacity will, and probably must, take place. However, nuclear energy and the use of radionuclides for civilian and military purposes lead to extremely long-lived waste that is costly and highly problematic to deal with. Therefore, it is critically important ot understand the environmental implications of radionuclides for ecosystems and human health if nuclear energy is to be used to avoid the impending global energy crisis. The present volume of the EIC Books series addresses this critical need by providing fundamental information on environmentally significant radionuclides. The content of this book was developed in collaboration with many of the authors of the chapters. Given the enormity of the subject the Editor and the Authors had to be judicious in selecting the chapters that would appropriately encompass and describe the primary topics, particularly those that are of importance to the health of ecosystems and humans. The resulting chapters were chosen to provide this information in a book of useful and appropriate length. Each chapter provides fundamental information on the chemistry of the radionuclides, their occurrence and movement in the enivornment, separation and analyses, and the technologies needed for their remediation and mitigation. The chapters are structured with a common, systematic format in order to facilitate comparions between elements and groups of elements. About EIC Books The Encyclopedia of Inorganic Chemistry (EIC) has proved to be one of the defining standards in inorganic chemistry, and most chemistry libraries around the world have access either to the first of second print editon, or to the online version. Many readers, however, prefer to have more concise thematic volumes, targeted to their specific area of interest. This feedback from EIC readers has encouraged the Editors to plan a series of EIC Books, focusing on topics of current interest. They will appear on a regular basis, and will feature leading scholars in their fields. Like the Encyclopedia, EIC Books aims to provide both the starting research student and the confirmed research worker with a critical distillation of the leading concepts in inorganic and bioinorganic chemistry, and provide a structured entry into the fields covered. This volume is also available as part of Encyclopedia of Inorganic Chemistry, 5 Volume Set. This set combines all volumes published as EIC Books from 2007 to 2010, representing areas of key developments in the field of inorganic chemistry published in the Encyclopedia of Inorganic Chemistry.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides an overview of the phenomenology, technology and application of secondary ion mass spectrometry as a technique for materials analysis. This approach is developing into one of the most effective methods of characterizing the composition and chemical state of the surface and sub-surface layers of solid materials. The first three chapters introduce the basic physical and chemical principles involved and the theories which have been proposed to explain the process. Subsequent chapters describe the instrumental components of the SIMS apparatus, the use of SIMS as an analytical tool, and the development of the techniques of sputtered neutral mass spectrometry and laser microprobe and plasma desorption mass spectrometry. Many practical examples are featured to illustrate the application of SIMS to real problems, possible pitfalls are pointed out, and data of use to analysts are collected in appendices. The book is a practical guide suitable for scientists in all fields who wish to use this valuable analytical technique.

Available in PDF, EPUB and Kindle. Book excerpt: The Conference on the Benthic Boundary Layer was held under the auspices of the NATO Science Committee as part of its continuing effort to promote the useful progress of science through international cooperation. Science Committee Conferences are deliberately designed to focus attention on unsolved problems, with carefully selected participants invited to provide complementary expertise from a variety of relevant disciplines. Through inten sive discussion in small groups they seek to reach a consensus on assessments and recommendations for future research emphasis, which it is hoped will be of value to the larger scientific community. The subjects treated over the past few years have been as varied as science itself-e.g., computer software engineering, chemical catalysis, and materials and energy research. The present effort evolved from informal discussions between marine geolo gists, chemists, and biologists which underlined the desirability of improved communication among those concerned with the benthic layer. In both scien tific and technological terms this is an exciting frontier, rich in promise but poorly understood at present. It is particularly striking to realize that there are at least as many definitions of the benthic layer as there are disciplines involved, and it seemed clear that there was much to be gained by a detailed exchange of views on research capabilities, trends, and priorities. The results of the meeting appear to have confirmed the hopes of the sponsors.

Available in PDF, EPUB and Kindle. Book excerpt: This book gives an overview of various aspects of blue carbon dynamics from each country bordering the Indian Ocean. Given the importance of the topic of blue carbon, it can be assumed that in near future, more and more researchers from the Indian Ocean countries will pursue environmental research in this domain. This book is a ready reference to all those who are interested to have a holistic understanding about the ground scenario of blue carbon in the Indian Ocean. There are many research institutes situated in the periphery of the Indian Ocean that are devoted to nurturing the new avenues of marine carbon research. Researchers and scholars interested in this domain will find this book provides a good overview, wherein all the necessary information on the status and functioning of these blue carbon ecosystems are detailed in a concise way. The book is also helpful to postgraduate students of ‘marine science’ or those who have a specialization in ‘marine biogeochemistry’ or ‘chemical oceanography’ to develop a basic understanding about the very concept of ‘blue carbon’ from the perspective of the Indian Ocean.
