  1. 11. Rapid analysis of actinide isotopes using quadrupole ICP-MS for emergency preparedness and environmental monitoring

    Författare :Christina Greis; Stefan Karlsson; Bert Allard; Anders Düker; Håkan Pettersson; Gi-Hoon Hong; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; quadrupole ICP-MS; actinides; plutonium; preparedness; NATURAL SCIENCES; NATURVETENSKAP; Chemistry; Kemi; Environmental chemistry; Miljökemi; Enviromental Science; Miljövetenskap;

    Sammanfattning : Transuranium elements in the environment are mainly derived from nuclear weapons testing and the nuclear fuel cycle. Of growing concern are illicit nuclear trafficking and the threat of terror acts. LÄS MER

  3. 12. Internal Dosimetry in Nuclear Fuel Fabrication : Occupational Exposure to Uranium Aerosols

    Författare :Edvin Hansson; Mats Eriksson; Håkan Pettersson; Per Roos; Michael Sandborg; Bastian Breustedt; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Uranium; Aerosol; Internal; Dose; Nuclear;

    Sammanfattning : The production of nuclear fuel can be associated with occupational exposure to ionizing radiation from radioactive decay of uranium. Such exposure must be sufficiently low and radiation doses adequately determined. Radiation doses from internal exposure, i.e. LÄS MER

  4. 13. Gold Electrodeposition in Semiconductor Nanowire Technology

    Författare :Reza Jafari Jam; Håkan Pettersson; Lars Samuelson; Magnus T. Borgström; Mikael Björk; Sweden Lund Lund University; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Semiconductor nanowires are widely considered as promising candidates for next generations of electronics and optoelectronics. Gold seed particles have so far been recognized as the most important catalyst for growth of nanowires. LÄS MER

  5. 14. Radon in natural waters : Analytical Methods; Correlation to Environmental Parameters; Radiation Dose Estimation; and GIS Applications

    Författare :Isam M. Musa Salih; Eva Lund; Håkan B.L. Pettersson; Christer Samuelsson; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radon analysis; radiation effects; Water chemistry; Water pollution; radioactive analysis; Radiological physics; Radiofysik;

    Sammanfattning : Investigations of radon in natural water and its relation to physical and chemical parameters are outlined in this thesis. In particular, a method for measuring 222Rn in water at low concentrations (~20 mBq. LÄS MER

  7. 15. Bridge Edge Beams : LCCA and Structural Analysis for the Evaluation of New Concepts

    Författare :José Javier Veganzones Muñoz; Lars Pettersson; Costin Pacoste; Raid Karoumi; Håkan Sundquist; Morgan Johansson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Civil and Architectural Engineering; Byggvetenskap;

    Sammanfattning : Bridge edge beams in Sweden may involve up to 60% of the life-cyclemeasure costs incurred along the road bridge’s life span. Moreover, usercosts as means of traffic disturbances are caused. Consequently, the SwedishTransport Administration started a project to find better alternativeedge beam design proposals for the society. LÄS MER
