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.

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.

This book was released on 2007 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past decade significant progress has been achieved in the development of waste characterization and control procedures and equipment as a direct response to ever-increasing requirements for quality and reliability of information on waste characteristics. Failure in control procedures at any step can have important, adverse consequences and may result in producing waste packages which are not compliant with the waste acceptance criteria for disposal, thereby adversely impacting the repository. The information and guidance included in this publication corresponds to recent achievements and reflects the optimum approaches, thereby reducing the potential for error and enhancing the quality of the end product. -- Publisher's description.

Available in PDF, EPUB and Kindle. Book excerpt: Applications of Liquid Scintillation Counting deals with liquid scintillation counting and its applications in fields such as the biosciences, medicine, environmental and space sciences, chemistry, and physics. These applications include dual-labeled counting; Cerenkov counting; radioimmunoassay, chemiluminescence and bioluminescence; pulse shape discrimination; flow cell counting; and large-volume counters. This book is comprised of 18 chapters and begins with a historical overview of the liquid scintillation method, the first liquid scintillation counters, and early scintillator solutes. The following chapters focus on the theory of liquid scintillation counting; the components of the liquid scintillator solution; and the development of the liquid scintillation counter and multiplier phototubes. The discussion then turns to the detection and measurement of different types of particles produced by radionuclides using liquid scintillation techniques; the techniques and problems of sample preparations (homogeneous and heterogeneous); oxidation techniques; and importance and difference of several types of counting vials. The sources of quenching in counting samples and methods of monitoring and correction for variable quench within samples are also considered. Several special applications of liquid scintillation techniques are presented, including dual-labeled counting, radioimmunoassay, and flow cell counting. In conclusion, the statistical considerations involved in determining the reliability and accuracy of data obtained by nuclear counting techniques are highlighted. This monograph will serve as a reliable source of information for those who are already using or starting to use liquid scintillation counting techniques.

Download or read book New Advanced in Alpha Spectrometry by Liquid Scintillation Methods written by and published by . This book was released on 1979 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Although the ability to count alpha particles by liquid scintillation methods has been long recognized, limited use has been made of the method because of problems of high background and alpha energy identification. In recent years some new developments in methods of introducing the alpha-emitting nuclide to the scintillator, in detector construction, and in electronics for processing the energy analog and time analog signals from the detector have allowed significant alleviation of the problems of alpha spectrometry by liquid scintillation. Energy resolutions of 200 to 300 keV full peak width at half maximum and background counts of 0.01 counts/min with rejection with rejection of 99% of all beta plus gamma interference is now possible. Alpha liquid scintillation spectrometry is now suitable for a wide range of applications, from the accurate quantitative determination of relatively large amounts of known nuclides in laboratory-generated samples to the detection and identification of very small, subpicocurie amounts of alpha emitters in environmental-type samples. Suitable nuclide separation procedures, sample preparation methods, and instrument configurations are available for a variety of analyses.
Download or read book Alpha Particle Analysis Using PEARLS Spectrometry written by and published by . This book was released on 1984 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Alpha particle assay by conventional plate-counting methods is difficult because chemical separation, tracer techniques, and/or self-absorption losses in the final sample may cause either non-reproducible results or create unacceptable errors. PEARLS (Photon-Electron Rejecting Alpha Liquid Scintillation) Spectrometry is an attractive alternative since radionuclides may be extracted into a scintillator in which there would be no self-absorption or geometry problems and in which up to 100% chemical recovery and counting efficiency is possible. Sample preparation may include extraction of the alpha emitter of interest by a specific organic-phase-soluble compound directly into the liquid scintillator. Detection electronics use energy and pulse-shape discrimination to provide discrete alpha spectra and virtual absence of beta and gamma backgrounds. Backgrounds on the order of 0.01 cpm are readily achievable. Accuracy and reproducibility are typically in the 100 +-1% range. Specific procedures have been developed for gross alpha, uranium, plutonium, thorium, and polonium assay. This paper will review liquid scintillation alpha counting methods and reference some of the specific applications. 8 refs., 1 fig.
