  1. 1. Methods for the Assessment of Long-Lived Radionuclides in Humans Resulting from Nuclear Activities or Accidents - Fission track analysis of trace-amounts 239Pu and a copper hexacyanoferrate kit for monitoring radiocaesium

    Författare :Lena Johansson; Lund Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; caesium; plutonium; fission track analysis; urine; internal contamination; whole-body counting; Physics; Chernobyl; Fysik; Chemistry; Kemi;

    Sammanfattning : Fission track analysis (FTA) was developed to be applied to ultra-low levels of 239Pu in bioassay samples. An analytical protocol was established for the FTA processing. The detection limit was determined to 1.5 µBq and the calibration constant was 24 fission fragments per µBq 239Pu. LÄS MER

  4. 3. Digital speckle photography and digital holography for the study of transparent media

    Författare :Eva-Lena Johansson; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimentell mekanik; Experimental Mechanics;

    Sammanfattning : In the fields of combustion and fluid mechanics, temperature- and density fields are of interest to measure. Optical measurement methods may be used to study such transparent media. Flames, gases and liquids are examples of transparent media, often called phase objects in an optical context. LÄS MER

  5. 4. Optical methods for the study of transparent media

    Författare :Eva-Lena Johansson; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimental Mechanics; Experimentell mekanik;

    Sammanfattning : In the fields of combustion and fluid mechanics, temperature-, density- and velocity fields are of interest to measure. Optical methods may be used to study transparent media, even transient events. Flames, gases and liquids are examples on transparent media, often called phase objects. LÄS MER
