Download or read book Liquid Scintillation Alpha Spectrometry written by W. McDowell and published by CRC Press. This book was released on 2018-01-18 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alpha liquid scintillation was developed to obtain accurate analytical determinations of alpha-emitting nuclides where no other methods were sufficiently accurate. With the present emphasis on clean-up of radiation contamination, alpha liquid scintillation has become an important tool in the determination of low concentrations of alpha-emitting nuclides. This book is the first to address the subject of alpha liquid scintillation in its entirety. It also examines how alpha spectrometry by liquid scintillation can be done without interference from beta/gamma radiation. Scientists interested in the analysis of alpha-emitting nuclides for environmental monitoring, remediation clean-up, accountability, and research will find this to be a valuable book.

Book excerpt: Liquid Scintillation: Science and Technology contains the proceedings of the International Conference on Liquid Scintillation: Science and Technology held on June 14-17, 1976 at the Banff Centre in Alberta, Canada. The book presents papers on the mechanisms of the liquid scintillation process; liquid scintillation alpha counting and spectrometry and its application to bone and tissue samples; and measurement by liquid scintillator of labelled compounds (3H or 14C) dropped onto supports. The text also includes papers on the heterogeneous counting on filter support media; liquid scintillation in medical diagnosis; and the theory and application of Cerenkov counting. The radioassay of chlorine using a liquid scintillation spectrometer; some factors influencing external standardization; and the study of the sizes and distributions of colloidal water in water-emulsifier-toluene systems are also considered. The book further tackles the external standard method of quench correction; the liquid scintillation counting of novel radionuclides; and Cerenkov counting and liquid scintillation counting for the determination of fluorine. The text also looks into the absolute disintegration rate determination of beta-emitting radionuclides by the pulse height shift-extrapolation method; automatic data processing in scintillation counting; and the standardization in liquid scintillation counting. Biochemists and scientists involved in the study of chemical biodynamics will find the book invaluable.
Download or read book Liquid scintillation Alpha detection Techniques written by and published by . This book was released on 1983 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Accurate, quantitative determinations of alpha-emitting nuclides by conventional plate-counting methods are difficult because of sample self-absorption problems in counting and because of non-reproducible losses in conventional sample separation methods. Liquid scintillation alpha spectrometry offers an attractive with no sample self-absorption or geometry problems and with 100% counting efficiency. Sample preparation may include extraction of the alpha emitter of interest by a specific organic-phase-soluble compound directly into the liquid scintillation counting medium. Detection electronics use energy and pulse-shape discrimination to yield alpha spectra without beta and gamma background interference. Specific procedures have been developed for gross alpha, uranium, plutonium, thorium, and polonium assay. Possibilities for a large number of other applications exist. Accuracy and reproducibility are typically in the 1% range. Backgrounds on the order of 0.01 cpm are readily achievable. The paper will present an overview of liquid scintillation alpha counting techniques and some of the results achieved for specific applications.

The first volume contains 37 papers mainly dealing with the physical aspects of liquid scintillation science and technology. The present volume contains papers that cover sample preparation, flow counting, and emulsion (solgel) counting. It also includes studies on applications of liquid scintillation counting, such as chemiluminescence and bioluminescence, environmental monitoring, and biomedical and radioimmunoassays.

Available in PDF, EPUB and Kindle. Book excerpt: Biological Applications of Liquid Scintillation Counting, based on a series of lectures given at the Worcester Foundation for Experimental Biology, discusses the various biological applications of liquid scintillation counting and presents its principles in a manner that is simple, practical, and useful. This book explains the fundamentals of scintillators and the scintillation process, from sample preparation to testing and setting up a counter and the application of radiotracers. This text is organized into six chapters and begins with a historical overview of liquid scintillation counting, emphasizing two major events that stimulated its development: the discovery of organic compounds called ""scintillators"" and the introduction of photomultiplier tubes. This book considers the factors that affect the performance of photomultiplier tubes, including temperature and magnetic fields, and the use of liquid scintillation counting to measure radioactivity. The discussion then shifts to the factors that must be taken into account when choosing a method for preparing samples, including the physical and chemical characteristics of the sample, the isotope or isotopes of the sample, and the anticipated level of radioactivity. The following chapters look at the general considerations when installing a liquid scintillation counter, procedures for applying radiotracers, and practical aspects of sample preparation. This book is intended for physicists and experimental biologists.

This book was released on 1977 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two sample changers are described that were designed for liquid scintillation counting of alpha-emitting samples prepared using solvent-extraction chemistry. One operates manually but changes samples without exposing the photomultiplier tube to light, allowing the high voltage to remain on for improved stability. The other is capable of automatically counting up to 39 samples. An electronic control for the automatic sample changer is also described.
Download or read book Liquid Scintillation Alpha Counting and Spectrometry and Its Application to Bone and Tissue Samples written by and published by . This book was released on 1976 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Three methods for determination of alpha-emitting nuclides using liquid scintillation counting are compared, and the pertinent literature is reviewed. Data showing the application of each method to the measurement of plutonium concentration in tissue and bone samples are presented. Counting with a commercial beta-liquid scintillation counter and an aqueous-phase-accepting scintillator is shown to be accurate only in cases where the alpha activity is high (several hundred counts/min or more), only gross alpha counting is desired, and beta-gamma emitters are known to be absent from the sample or present at low levels compared with the alpha activity. Counting with the same equipment and an aqueous immiscible scintillator containing an extractant for the nuclide of interest (extractive scintillator) is shown to allow better control of alpha peak shift due to quenching, a significant reduction of beta-gamma interference, and, usually, a low background. The desirability of using a multichannel pulse-height analyzer in the above two counting methods is stressed. The use of equipment and procedures designed for alpha liquid scintillation counting is shown to allow alpha spectrometry with an energy resolution capability of 200 to 300 keV full-peak-width-at-half-peak-height and a background of 0.3 to 1.0 counts/min, or as low as 0.01 counts/min if pulse-shape discrimination methods are used. Methods for preparing animal bone and tissue samples for assay are described.
