Radiochemical measurement uncertainties The art of expressing measurement uncertainties can be a lifelong pursuit. The first three steps are the most difficult to do: (1) describing the measurement model, (2) listing standard uncertainty components and estimating values for each, and (3) combining the standard uncertainties. This work, primarily based on ANSI Standard Guide D8293-19, provides starter lists of uncertainty components, and suggestions for addressing correlations among them. The net effect of this effort is to assist the reader to recognize a number of heretofore "dark uncertainty" [unidentified] components in their measurement process so that they may be successfully reduced, understood, and controlled.

Radiochemistry and nuclear chemistry workforce The disciplines of radiochemistry and nuclear chemistry have direct applications in the fields of national security, nuclear medicine, nuclear power production, and environmental management. Although, often, nuclear and radiochemistry are grouped together and many experts work in both areas, the definition for each field is slightly different. For example, radiochemistry may be defined as the application of the phenomena of radioactive decay and techniques common to nuclear physics so as to solve problems in the field of chemistry. In contrast, nuclear chemistry may be defined as the application of procedures and techniques common to chemistry to study the structure of the atomic nucleus. This chapter provides a brief update of the current state of, and critical U.S. needs for, nuclear chemistry and radiochemistry expertise as the Assuring a Future U.S.?Based Nuclear and Radiochemistry Expertise report was published by National Academy of Sciences (NAS) in 2012.

Scintillation Counting The Theory and Practice of Scintillation Counting is a comprehensive account of the theory and practice of scintillation counting. This text covers the study of the scintillation process, which is concerned with the interactions of radiation and matter; the design of the scintillation counter; and the wide range of applications of scintillation counters in pure and applied science. The book is easy to read despite the complex nature of the subject it attempts to discuss. It is organized such that the first five chapters illustrate the fundamental concepts of scintillation counting. Chapters 6 to 10 detail the properties and applications of organic scintillators, while the next four chapters discuss inorganic scintillators. The last two chapters provide a review of some outstanding problems and a postscript. Nuclear physicists, radiation technologists, and postgraduate students of nuclear physics will find the book a good reference material.

radiochemical methods The aim of this book is to give an account of the principal radiochemical methods used in chemical analysis. It is assumed that the reader already has some background knowledge of radioactivity, available from several general textbooks. For this reason, some subjects, e. g. the fundamentals of radio activity, the properties of radiation, statistics of counting procedures, the precautions needed in working with radioactive materials, which could have occupied half the text, are not considered in detail. The different aspects of radiochemical analysis have been covered by specialized books and reviews, e. g. on activation analysis, gamma spectrometry, radiometric titrations. A good deal of information is in the form of reports of meetings and symposia and liquid scintillation counting, for instance, has been mainly covered in this way. There are also a large number of journals. It is therefore hoped that this book will help fill the gap between the introductory texts and the specialized sources, many of which are referred to in the chapter references. The first three chapters in the present volume deal with the methods of measurement of radioactive nuclides. Chapter I gives a general account of detection and measurement techniques. The next two chapters are devoted to two specialized techniques: gamma-ray spectrometry and liquid scintillation counting.

gamma spec, detection, uncertainty analysis Dedicated specifically to nuclear analytical techniques, this publication is intended to assist scientists using alpha, beta and gamma spectrometries, neutron activation and XRF analyses, and other nuclear analytical methods, in assessing and quantifying the sources of uncertainty in their daily measurements. It complements the ‘Guide to the Expression of Uncertainty in Measurement’ published by ISO and other organizations in 1993, and the EURACHEM Guide on ‘Quantifying Uncertainty in Analytical Measurement’, the second edition of which was published in 2000. Thirteen selected examples of quantification of measurement uncertainty covering a number of nuclear analytical techniques and different measurand/matrix combinations are elaborated in detail. This publication may therefore be used as a course material as well as guidance in the assessment of competence for accreditation and similar purposes for laboratories applying nuclear analytical techniques.

nuclear chemistry, radiochemistry, radiotracers The third edition of this classic in the field is completely updated and revised with approximately 30% new content so as to include the latest developments. The handbook and ready reference comprehensively covers nuclear and radiochemistry in a well-structured and readily accessible manner, dealing with the theory and fundamentals in the first half, followed by chapters devoted to such specific topics as nuclear energy and reactors, radiotracers, and radionuclides in the life sciences. The result is a valuable resource for both newcomers as well as established scientists in the field.
