This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "During sampling or remediation of radiologically contaminated sites quantitative results are needed to determine where to sample or where to excavate soils. Although some portable gamma spectroscopy equipment does exist for field identification of radionuclides, they are not commonly used during remedial investigations. The current, and very common, process for sampling involves scanning soil with field portable gross measuring radiation detectors (i.e. sodium iodide, scintillation, etc.) that measure counts per minute of ionizing radiation; this does not give any information on the nuclides present or their concentrations in the soil. Samples are then collected at biased locations, based on the results of the field detectors, and sent to an on-site or off-site laboratory for analysis (i.e. gamma-spectroscopy, alpha-spectroscopy, etc. ) to determine what nuclides are in the soil and quantitate their concentration. If an on-site laboratory is not used it may take a few weeks to receive data back from off-site analysis, which inhibits real-time decision making while sampling and adds costs to a project. One potential method to determine real-time concentrations of metals in soil is through the use of a field portable x-ray fluorescence (XRF) device. This thesis will examine the relationship between laboratory isotopic thorium and uranium to XRF results of elemental uranium and thorium which are contaminants of concern found at Formally United Remedial Action Program (FUSRAP) sites. The FUSRAP properties were contaminated during the United States early atomic weapons era and are being remediated by the United States Army Corps of Engineers (USACE) as part of a federal remediation program. Both thorium and uranium are radioactive metals that will be investigated to determine if XRF devices can detect their presence at environmental levels of significance to assist in the investigation and remediation of future FUSRAP projects."--Abstract.

This book was released on 2022-10-19 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last two decades, advances in the design, miniaturization, and analytical capabilities of portable X-ray fluorescence (pXRF) instrumentation have led to its rapid and widespread adoption in a remarkably diverse range of applications in research and industrial fields. The impetus for this volume was that, as pXRF continues to grow into mainstream use, analysts should be increasingly empowered with the right information to safely and effectively employ pXRF as part of their analytical toolkit. This volume provides introductory and advanced-level users alike with readings on topics ranging from basic principles of pXRF and qualitative and quantitative approaches, through to machine learning and artificial intelligence for enhanced applications. It also includes fundamental guidance on calibrations, the mathematics of calculating uncertainties, and an extensive reference index of all elements and their interactions with X-rays. Contributing authors have provided a wealth of information and case studies in industry-specific chapters. These sections delve into detail on current standard practices in industry and research, including examples from agricultural and geo-exploration sectors, research in art and archaeology, and metals industrial and regulatory applications. As pXRF continues to grow in use in industrial and academic settings, it is essential that practitioners continue to learn, share, and implement informed and effective use of this technique. This volume serves as an accessible guidebook and go-to reference manual for new and experienced users in pXRF to achieve this goal.

Download or read book X Ray Fluorescence Spectrometry XRF in Geoarchaeology written by M. Steven Shackley and published by Springer Science & Business Media. This book was released on 2010-10-17 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the 1960s, x-ray fluorescence spectrometry (XRF), both wavelength and energy-dispersive have served as the workhorse for non-destructive and destructive analyses of archaeological materials. Recently eclipsed by other instrumentation such as LA-ICP-MS, XRF remains the mainstay of non-destructive chemical analyses in archaeology, particularly for volcanic rocks, and most particularly for obsidian. In a world where heritage and repatriation issues drive archaeological method and theory, XRF remains an important tool for understanding the human past, and will remain so for decades to come. Currently, there is no comprehensive book in XRF applications in archaeology at a time when the applications of portable XRF and desktop XRF instrumentation are exploding particularly in anthropology and archaeology departments worldwide. The contributors to this volume are the experts in the field, and most are at the forefront of the newest applications of XRF to archaeological problems. It covers all relevant aspects of the field for those using the newest XRF technologies to deal with very current issues in archaeology.

Book excerpt: X-ray fluorescence spectrometry (XRF) is a well-established analytical technique for qualitative and quantitative elemental analysis of a wide variety of routine quality control and research samples. Among its many desirable features, it delivers true multi-element character analysis, acceptable speed and economy, easy of automation, and the capacity to analyze solid samples. This remarkable contribution to this field provides a comprehensive and up-to-date account of basic principles, recent developments, instrumentation, sample preparation procedures, and applications of XRF analysis. If you are a professional in materials science, analytic chemistry, or physics, you will benefit from not only the review of basics, but also the newly developed technologies with XRF. Those recent technological advances, including the design of low-power micro- focus tubes and novel X-ray optics and detectors, have made it possible to extend XRF to the analysis of low-Z elements and to obtain 2D or 3D information on a micrometer-scale. And, the recent development and commercialization of bench top and portable instrumentation, offering extreme simplicity of operation in a low-cost design, have extended the applications of XRF to many more analytical problems.
