Radioactive Isotope Tracer Techniques

"The book entitled Radio Tracer Techniques for Agriculturists and Biologist narrates the fundamentals and principles behind radio tracer techniques. Its application in agriculture and biological sciences and also the instrumentation and laboratory set up with safety aspects required to be followed while working with radio active substances. This is a comprehensive collection useful to all concerned with radio tracers."

The idea of using tracers (chemical tracers, dyes, etc.) in the investigation of complex physical phenomena has always attracted the attention of scientists and engineers. When radioactive isotopes became available it was immediately recognized that they offered an almost ideal solution to tracer selection. Extensive experience has been gathered all over the world in the application of radioactive tracers in industry. This guide is devoted to reviewing the present status of the tracer method as such and to its applications to those branches of industry which have derived large benefits from the use of this technology.

Radioactive Tracers in Biology: An Introduction to Trace Methodology, Second Edition focuses on the biochemical and physiological aspects of tracer research, including medical applications of tracer techniques, radioactivity, radiation hazards, and radioactive isotopes. The book first offers information on atomic nuclei, radioactivity, and the production of radioactive isotopes and radiation characteristics of tracer atoms. Discussions focus on nuclear reactions, neutron-induced and deuteron-induced transmutations, properties of atomic nuclei, and target techniques and radiochemistry. The manuscript also ponders on the procedures for radioactive assay and radiation hazards. The text examines the biochemical, medical, and physiological applications of tracer methodology. The manuscript also takes a look at radioactive hydrogen, short-lived and long-lived radioactive carbon, radioactive phosphorus and sulfur, and alkali metal and alkaline earth tracers. Topics include synthesis of organic intermediates for tracer carbon studies; biosynthesis of labeled carbon compounds; and general survey of alkali metal tracers. The publication is a dependable reference for readers interested in radioactive tracers.

The latest of a series of publications based on workshops sponsored by the Committee on Military Nutrition Research, this book's focus on emerging technologies for nutrition research arose from a concern among scientists at the U.S. Army Research Institute of Environmental Medicine that traditional nutrition research, using standard techniques, centered more on complex issues of the maintenance or enhancement of performance, and might not be sufficiently substantive either to measure changes in performance or to predict the effects on performance of stresses soldiers commonly experience in operational environments. The committee's task was to identify and evaluate new technologies to determine whether they could help resolve important issues in military nutrition research. The book contains the committee's summary and recommendations as well as individually authored chapters based on presentations at a 1995 workshop. Other chapters cover techniques of body composition assessment, tracer techniques for the study of metabolism, ambulatory techniques for the determination of energy expenditure, molecular and cellular approaches to nutrition, the assessment of immune function, and functional and behavioral measures of nutritional status.

This 1958 book sets out the elementary precautions to be taken by anyone handling radioactive isotopes in laboratories. The introductory sections explain the types of radiation encountered, and enumerate the possible dangers from external sources, accidental ingestion and contamination of the body. The safety techniques for various laboratory experiments and the proper methods of disposal of radioactive waste are described in some detail. A final section on laboratory administration is followed by a convenient summary of 'dos' and do nots' for safe working. The appendices include a classified table of isotopes and their toxicity, diagrams of protective equipment, and details of the shielding necessary for emissions of given energy. Dr Boursnell confines his discussion to the common essentials of all laboratory techniques; his book will be of value to anyone with an interest in the active materials.

Isotopic Tracers in Biology: An Introduction to Tracer Methodology, Third Edition focuses on stable isotopes, structures, composition, and reactions of nitrogen and oxygen, and radioactive tracers. The book first takes a look at atomic nuclei, radioactivity, and the production of radioactive isotopes and radiation characteristics of tracer atoms. Topics include nuclear reactions, general properties of nuclei, radioactivity, target techniques and radiochemistry, and beta and gamma radiations. The text also discusses isotopic assay, radiation hazards, procedures related with sample preparation for radioactive assay, and combustion of labeled materials. The manuscript examines the biochemical, physiological, and medical aspects of tracer methodology, as well as biochemical applications, value of tracer methods for biology, intermediary metabolism, and applications to clinical research. The text also ponders on the isotopes of hydrogen, carbon, oxygen, nitrogen, phosphorus, and sulfur. Concerns include assay of deuterium and tritium, short-lived and heavy stable carbon, and oxygen, nitrogen, sulfur, and phosphorus isotopes. The publication is a dependable reference for readers interested in isotopic tracers.

This book serves as a practical guide and a manual on the application of isotopic tracers in understanding the cellular processes (e.g. molecular interactions, protein synthesis) in growth, development, and disease conditions. The techniques described in the book have been carefully chosen to underscore the role and relevance of isotopic tracers in the identification of molecular targets and mechanisms, and preclinical validation of potential therapeutics. This book is intended to be a valuable resource to non-experts that may include students, researchers, educators/teachers, and others who have an interest to understand the application of isotopic tracers in research. Each chapter includes a background, an outline of the method and underlying principles, and a detailed step-wise protocol. To augment the clarity and intellectual grasp, the chapters also include relevant illustrations and study questions. More importantly, the book covers techniques involving radioactive as well as non-radioactive tracers to expand the scope of isotopes in preclinical research including basic and applied science.
