    CASE FILE COPY NASA SP-7031 Properties of Selected Radioisotopes A Bibliography PART I: UNCLASSIFIED LITERATURE NATIONAL AERONAUTICS AND SPACE ADMINISTRATION NASA SP-7031 PROPERTIES OF SELECTED RADIOISOTOPES A Bibliography Part I: Unclassified Literature A selection of annotated references to technical papers, journal articles, and books This bibliography was compiled and edited by DALE HARRIS and JOSEPH EPSTEIN Goddard Space Flight Center Greenbelt, Maryland Scientific and Technical Information Division / OFFICE OF TECHNOLOGY UTILIZATION 1968 USP. NATIONAL AERONAUTICS AND SPACE ADMINISTRATION Washington, D.C. PREFACE The increasing interest in the application of substantial quantities of radioisotopes for propulsion, energy conversion, and various other thermal concepts emphasizes a need for the most recent and most accurate information available describing the nuclear, chemical, and physical properties of these isotopes. A substantial amount of progress has been achieved in recent years in refining old and developing new techniques of measurement of the properties quoted, and isotope processing. This has resulted in a broad technological base from which both the material and information about the material is available. Un- fortunately, it has also resulted in a multiplicity of sources so that information and data are either untimely or present properties without adequately identifying the measurement techniques or describing the quality of material used. The purpose of this document is to make available, in a single reference, an annotated bibliography and sets of properties for nine of the more attractive isotopes available for use in power production. Part I contains all the unclassified information that was available in the literature surveyed. Part II is the classified counterpart to Part I.

  • Measurement of Cerium in Human Breast Milk and Blood
    Measurement of cerium in human breast milk and blood Vera Höllriegl, Montserrat Gonzáles-Estecha*, Elena M. Trasobares*, Augusto Giussani, Uwe Oeh, Miguel Angel Herraiz**, Bernhard Michalkea Institute of Radiation Protection and aInstitute of Ecological Chemistry, Helmholtz Zentrum München, German Research Center for Environmental Health, Ingolstädter Landstrasse 1, 85764 Neuherberg, Germany *Trace Element Unit, Department of Laboratory Medicine and **Department of Obstetrics and Gynaecology, Hospital Clinico Universitario San Carlos, 28040 Madrid, Spain Abstract The aim of this study was to evaluate the relationship between cerium content in human breast milk and blood plasma or serum and the influence due to the environmental exposure. Blood samples and breast milk at various stages of lactation, from 5 days to 51 weeks post partum, were donated by 42 healthy breast-feeding mothers from Munich, Germany and by 26 lactating Spanish mothers from Madrid at 4 weeks post partum. Inductively coupled plasma mass spectrometry was applied for the determination of cerium in the biological samples. Cerium concentration in the digested milk samples from Munich showed low values and the arithmetic mean values ranged between the quantification limit of 5 ng/L up to 65 ng/L. The median value amounted to 13 ng/L. The cerium concentrations in the Spanish breast milk samples amounted to similar low values. The data were about a factor of eight lower than values found in a former study of samples from an eastern German province. All cerium concentrations in the German plasma samples, except for two, were at the quantification limit of 10 ng/L. Interestingly, the serum samples of the Spanish mothers 1 showed cerium values ranging between 21.6 and 70.3 ng/L; these higher data could be explained by an enhanced intake of cerium by humans in Madrid.

It is named after the asteroid Ceres, which had been discovered just two years earlier. Cerium is a grayish lustrous metal that is malleable and has four allotropic modifications. The common γ-form occurs at ordinary temperatures and atmospheric pressures. The β-form occurs at -16 ºC, the α-form occurs below -172 ºC, and the δ-form occurs at elevated temperatures above 725 ºC. Cerium reacts with water, while the metal is stable in dry air at ordinary temperatures. Compounds of cerium have many important industrial applications as catalysts, especially in the glass industry. Misch metal, an alloy of cerium with other lanthanides, is a pyrophoric substance and is used to make gas lighters and ignition devices. Some other applications of the metal or its alloys are in solid-state devices, rocket propellant compositions, as a getter in vacuum tubes, and as a diluent for plutonium in nuclear fuel.

In the present work, results of the clearance of Ce in blood plasma are 24 shown after simultaneous intravenous and oral administration of a Ce tracer. Inductively coupled 25 plasma mass spectrometry was used to determine the tracer concentrations in plasma. The results show 26 that about 80% of the injected Ce citrate cleared from the plasma within the five minutes post- 27 administration. The data obtained are compared to a revised biokinetic model of cerium, which was 28 initially developed by the International Commission on Radiological Protection (ICRP). The measured 29 plasma clearance of Ce citrate was mostly consistent with that predicted by the ICRP biokinetic model. 30 Furthermore, in an effort to quantify the uncertainty of the model prediction, the laboratory animal 31 data on which the ICRP biokinetic Ce model is based, was analyzed.

  • Using Biomolecules to Separate Plutonium
    USING BIOMOLECULES TO SEPARATE PLUTONIUM by Jarrod Gogolski A thesis submitted to the Faculty and the Board of Trustees of the Colorado School of Mines in partial fulfillment of the requirements for the degree of Master of Science (Nuclear Engineering). Golden, Colorado Date ________________________ Signed: __________________________ Jarrod Gogolski Signed: __________________________ Dr. Mark Jensen Thesis Advisor Golden, Colorado Date ______________________ Signed: _________________________ Dr. Mark Jensen Professor and Director Nuclear Science and Engineering Program ii ABSTRACT Used nuclear fuel has traditionally been treated through chemical separations of the radionuclides for recycle or disposal. This research considers a biological approach to such separations based on a series of complex and interdependent interactions that occur naturally in the human body with plutonium. These biological interactions are mediated by the proteins serum transferrin and the transferrin receptor. Transferrin to plutonium in vivo and can deposit plutonium into cells after interacting with the transferrin receptor protein at the cell surface. Using cerium as a non-radioactive surrogate for plutonium, it was found that cerium(IV) required multiple synergistic anions to bind in the N-lobe of the bilobal transferrin protein, creating a conformation of the cerium-loaded protein that would be unable to interact with the transferrin receptor protein to achieve a separation. The behavior of cerium binding to transferrin has contributed to understanding how

  • Discovery of Cesium, Lanthanum, Praseodymium and Promethium Isotopes
    Discovery of Cesium, Lanthanum, Praseodymium and Promethium Isotopes E. May, M. Thoennessen∗ National Superconducting Cyclotron Laboratory and Department of Physics and Astronomy, Michigan State University, East Lansing, MI 48824, USA Abstract Currently, forty-one cesium, thirty-five lanthanum, thirty-two praseodymium, and thirty-one promethium, isotopes have been observed and the discovery of these isotopes is discussed here. For each isotope a brief synopsis of the first refereed publication, including the production and identification method, is presented. arXiv:1109.1784v1 [nucl-ex] 8 Sep 2011 ∗Corresponding author.
