  1. 16. Determination of Sr90 and the Transuranium Elements in the Event of a Nuclear Accident

    Författare :Ingvar Friberg; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; transuranium TRU elements; nuclear accident; Sr90; solvent extraction; radioanalysis; HDEHP; Cherenkov; DMDBTDMA;

    Sammanfattning : To reduce the health effects of a nuclear accident, it is essential that suitable analytical methods are available for determinations of radionuclides released to the environment. Sr90 and the transuranium (TRU) elements are of great radiological importance, and they are more difficult to measure than many other radionuclides. LÄS MER

  3. 17. Tellurium interaction with surfaces in the containment and sea-salt residue

    Författare :Fredrik Espegren; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; server nuclear accident; Keywords: tellurium; seawater; deposition; chemistry; containment;

    Sammanfattning : In the event of a nuclear accident, the release of radionuclides is always a concern. The extent of such releases is affected by several factors, for example type of atmosphere, temperature, and what structural materials are present during the accident. LÄS MER

  4. 18. Radiation and radionuclide measurements at radiological and nuclear emergencies. Use of instruments and methods intended for clinical radiology and nuclear medicine

    Författare :Ünal Ören; Malmö Medicinsk strålningsfysik; []
    Nyckelord :radiological and nuclear emergencies; detectors; imaging modalities; clinical radiology; nuclear medicine;

  5. 19. Nitride fuel production by the internal sol gel process

    Författare :Marcus Hedberg; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nitride fuels; ZrN; internal sol gel;

    Sammanfattning : AbstractDuring operation of a fourth generation reactor system it is necessarily not desirable to utilize an oxide fuel matrix as in light water reactor systems. One type of chemical compounds that has been suggested is nitride based nuclear fuel. LÄS MER

  7. 20. Applications of Magnetic Tracers in the Human Lung and Gastrointestinal Tract

    Författare :Mikael Forsman; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; inverse solution; gastrointestinal motility; inhaled particles; gastric emptying; welding dust; MPG; pulmonary clearance; occupational health; magnetopneumography; multipole analysis; transit time;

    Sammanfattning : The use of ferrimagnetic material as a tracer represents a noninvasive approach in physiological measurements. Concerning the lung, magnetopneumography, MPG, is a unique technique to estimate retained dust in the lung, using the magnetizable dust fraction as a tracer. First a strong constant magnetic field is briefly applied to the thorax. LÄS MER
