Download or read book Polyatomic Interferences on High Precision Uranium Isotope Ratio Measurements by MC ICP MS written by and published by . This book was released on 2015 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern mass spectrometry and separation techniques have made measurement of major uranium isotope ratios a routine task; however accurate and precise measurement of the minor uranium isotopes remains a challenge as sample size decreases. One particular challenge is the presence of isobaric interferences and their impact on the accuracy of minor isotope 234U and 236U measurements. Furthermore, we present techniques used for routine U isotopic analysis of environmental nuclear safeguards samples and evaluate polyatomic interferences that negatively impact accuracy as well as methods to mitigate their impacts.

Download or read book MC ICP MS Analysis of Uranium and Plutonium in Keratinous Samples for the Purposes of Nuclear Forensic and Biomarker Establishment written by John W. N. Brown (IV) and published by . This book was released on 2017 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: One objective of nuclear forensics is to identify the source of interdicted nuclear materials in order to help ensure the safety and security of special nuclear materials. Since 1995, The International Atomic Energy Agency (IAEA) has reported at least 16 different cases involving the illegal possession and transportation of either plutonium or enriched uranium. A non-invasive assay capable of identifying whether a person of interest has been exposed to special nuclear materials, either environmentally or occupationally, would greatly aid in an investigation of the suspected handling and transport of enriched uranium or plutonium. Human hair and nail are used as effective biomonitors for exposure and intake of numerous trace-elements and potential toxins. The objective of this work was to investigate the hypothesis that the isotopic ratio composition of U and Pu in human hair and nail are reflective of exposure to special nuclear materials. Fingernail, toenail, and hair samples were collected from volunteers from national labs (Idaho, Oakridge, LLNL, Y-12) who self-reported exposure to either U or Pu, under the purview of a DOE CENTRAL IRB and control samples were collected from individuals living in the Columbia, MO region who had no exposure to enriched or depleted uranium or plutonium. Both the concentration and U and Pu isotopic composition was determined using the analytical procedure developed as part of this work. Average uranium recovery was 105 ± 4%. [superscript 242]Pu recovery ranged from 65-101%. Both [superscript 235]U and [superscript 236]U isotope ratios indicated exposure to special nuclear materials in several occupationally exposed volunteers. [superscript 234]U isotope ratios were not correlated between controls or exposed workers. Additionally, concentration measurements for [superscript 238]U were not correlated with either controls or exposures. Four volunteers had measurable amounts of [superscript 239]Pu in their hair, nails, or toenails.

Download or read book The New Nuclear Forensics written by Vitaly Fedchenko and published by Oxford University Press. This book was released on 2015 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nuclear material changes its form and properties as it moves through the nuclear fuel cycle, from one facility to another. Each step of the fuel cycle or each use of the material will inevitably leave its mark. The science of determining the history of a sample of nuclear material through the study of these characteristics is known as nuclear forensics. While nuclear forensic analysis has normally been associated with investigations and prosecutions in the contextof trafficking of nuclear materials or nuclear terrorism, it had wider applications in in national security contexts, such as nuclear non-proliferation, disarmament, and arms control. The New Nuclear Forensics is the first book to give a definitive guide to this broader definition of nuclear forensic analysis. This book describes the various methods used in nuclear forensics, giving first a broad introduction to the process followed by details of relevant measurement techniques and procedures. In each case, the advantages and limitations are outlined. To put these methods in context, the book also recounts the history of the discipline anddescribes the diverse contemporary applications of nuclear forensics.
