Download or read book DETERMINATION OF 237NP AND PU ISOTOPES IN LARGE SOIL SAMPLES BY INDUCTIVELY COUPLED PLASMA MASS SPECTROMETRY written by and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A new method for the determination of 237Np and Pu isotopes in large soil samples has been developed that provides enhanced uranium removal to facilitate assay by inductively coupled plasma mass spectrometry (ICP-MS). This method allows rapid preconcentration and separation of plutonium and neptunium in large soil samples for the measurement of 237Np and Pu isotopes by ICP-MS. 238U can interfere with 239Pu measurement by ICP-MS as 238UH mass overlap and 237Np via 238U peak tailing. The method provides enhanced removal of uranium by separating Pu and Np initially on TEVA Resin, then transferring Pu to DGA resin for additional purification. The decontamination factor for removal of uranium from plutonium for this method is greater than 1 x 106. Alpha spectrometry can also be applied so that the shorter-lived 238Pu isotope can be measured successfully. 239Pu, 242Pu and 237Np were measured by ICP-MS, while 236Pu and 238Pu were measured by alpha spectrometry.

This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A new method that allows rapid preconcentration and separation of plutonium and neptunium in water samples was developed for the measurement of 237Np and Pu isotopes by inductively-coupled plasma mass spectrometry (ICP-MS) and alpha spectrometry; a hybrid approach. 238U can interfere with 239Pu measurement by ICP-MS as 238UH mass overlap and 237Np via peak tailing. The method provide enhanced removal of uranium by separating Pu and Np initially on TEVA Resin, then moving Pu to DGA resin for additional removal of uranium. The decontamination factor for uranium from Pu is almost 100,000 and the decontamination factor for U from Np is greater than 10,000. This method uses stacked extraction chromatography cartridges and vacuum box technology to facilitate rapid separations. Preconcentration is performed using a streamlined calcium phosphate precipitation method. Purified solutions are split between ICP-MS and alpha spectrometry so that long and short-lived Pu isotopes can be measured successfully. The method allows for simultaneous extraction of 20 samples (including QC samples) in 4 to 6 hours, and can also be used for emergency response. 239Pu, 242Pu and 237Np were measured by ICP-MS, while 236Pu, 238Pu, and 239Pu were measured by alpha spectrometry.

Download or read book Strategy and Methodology for Radioactive Waste Characterization written by International Atomic Energy Agency and published by IAEA. 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.

This book was released on 2007-12-31 with total page 4059 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Chemistry of the Actinide and Transactinide Elements is a contemporary and definitive compilation of chemical properties of all of the actinide elements, especially of the technologically important elements uranium and plutonium, as well as the transactinide elements. In addition to the comprehensive treatment of the chemical properties of each element, ion, and compound from atomic number 89 (actinium) through to 109 (meitnerium), this multi-volume work has specialized and definitive chapters on electronic theory, optical and laser fluorescence spectroscopy, X-ray absorption spectroscopy, organoactinide chemistry, thermodynamics, magnetic properties, the metals, coordination chemistry, separations, and trace analysis. Several chapters deal with environmental science, safe handling, and biological interactions of the actinide elements. The Editors invited teams of authors, who are active practitioners and recognized experts in their specialty, to write each chapter and have endeavoured to provide a balanced and insightful treatment of these fascinating elements at the frontier of the periodic table. Because the field has expanded with new spectroscopic techniques and environmental focus, the work encompasses five volumes, each of which groups chapters on related topics. All chapters represent the current state of research in the chemistry of these elements and related fields.
Download or read book Trace Analysis By Mass Spectrometry written by Arthur J. Ahearn and published by Elsevier. This book was released on 2012-12-02 with total page 475 pages. Available in PDF, EPUB and Kindle. Book excerpt: Trace Analysis by Mass Spectrometry deals with trace analysis of solids and liquids by mass spectrometric techniques. Topics include the physics and techniques of electrical discharge ion sources, transmission of ions through double focusing mass spectrometers, and detection and measurement of ions by ion-sensitive plates. The ion sources used are principally electrical discharge type sources. This book is comprised of 14 chapters. The first several chapters focus on the basic physics of electrical discharge ion sources, double focusing mass spectrometry, and the measurement of arrays of mass resolved ion beams by electrical detection methods and with ion sensitive emulsions. The discussion then shifts to the problem of obtaining the chemical composition of the recorded mass resolved ion sample and relating this composition to that of the original sample. The chapters that follow describe specific techniques for analyzing special samples such as insulators, powders, microsamples, biological materials, reactive and low melting point substances, radioactive materials, and gases in solids. The remaining chapters include the use of laser ion sources in the analysis of solids and the analysis of surfaces particularly with sputter ion sources. This book will be of interest to students and practitioners of physics and chemistry.
