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 Plutonium Bioassay by Inductively Coupled Plasma Mass Spectrometry ICP written by and published by . This book was released on 1993 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: The determination of plutonium in urine poses several analytical challenges, e.g., detectability, matrix, etc. We have investigated the feasibility of analyzing plutonium in processed urine by inductively coupled plasma mass spectrometry (ICP/MS). The urine samples are first spiked with [sup 244]Pu as a tracer and internal standard, then processed by co-precipitation and column chromatography using TRU-Spec[trademark], an extraction resin. By enhancing ICP/MS detection capabilities via improved sample introduction and data acquisition efficiencies, an instrumental detection limit of 5 to 50 fg (0.3 to 3 fCi for [sup 239]pu) is typically obtained, depending on the desired degree of quantitation. A brief summary of the analytical method as well as the basis for measuring radionuclides by ICP/MS are submitted; the separation procedure, methods of sample introduction, and data acquisition techniques are then highlighted.
Download or read book Radioactive Particles in the Environment written by Deborah Oughton and published by Springer. This book was released on 2009-07-31 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radioactive particles have been released to the environment from a number of sources, including nuclear weapon tests, nuclear accidents and discharges from nuclear installations. Particle characteristics influence the mobility, biological uptake and effects of radionuclides, hence information on these characteristics is essential for assessing environmental impact and risks. This publication presents a series of papers covering sources and source term characterisation, methodologies for characterizing particles, and the impact of particles on the behaviour of radioactive particles in the environment. Sources covered include the Chernobyl accident, nuclear weapons accidents at Thule and Palomares accident, the discharges from Dounreay and Krashnoyarsk, and depleted uranium in Kosovo and Kuwait. The overall aim is that an increased understanding of particle characteristics and behavior will help to reduce some of the uncertainties in environmental impact and risk assessment for particle contaminated areas.

Available in PDF, EPUB and Kindle. Book excerpt: The term “heavy metals” is used as a group name of toxic metals and metalloids (semimetals) causing contaminations and ecotoxicity. In strict chemical sense the density of heavy metals is higher than 5 g/cm3. From biological point of view as microelements they can be divided into two major groups. a. For their physiological function organisms and cells require essential microelements such as iron, chromium (III), cobalt, copper, manganese, molidenium, zinc. b. The other group of heavy metals is toxic to the health or environment. Of highest concern are the emissions of As, Cd, Co, Cu, Hg, Mn, Ni, Pb, Sn, Tl. The toxicity of heavy metals is well known at organizational level, while less attention has been paid to their cellular effects. This book describes the toxicity of heavy metals on microorganisms, yeast, plant and animal cells. Other chapters of the book deal with their genotoxic, mutagenic and carcinogenic effects. The toxicity of several metals touch upon the aspects of environmental hazard, ecosystems and human health. Among the cellular responses of heavy metals irregularities in cellular mechanisms such as gene expression, protein folding, stress signaling pathways are among the most important ones. The final chapters deal with biosensors and removal of heavy metals. As everybody is eating, drinking and exposed to heavy metals on a daily basis, the spirit of the book will attract a wide audience.
