    Sammanfattning : This thesis concerns a nuclear accident that occurred in the Thule (Pituffik) area, NW Greenland in 1968, called the Thule accident. Results are based on different analytical techniques, i.e. gamma spectrometry, alpha spectrometry, ICP-MS, SEM with EDX and different sediment models, i. LÄS MER

  3. 2. Development of the Lund AMS Facility for the Detection of 59Ni – with Applications in the Nuclear Industry

    Författare :Per Persson; Kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; AMS; Accelerator mass spectrometry; 59Ni; nuclear waste; chemical cobalt reduction; gas stripper; Nuclear engineering and technology; Kärnteknik; Fysicumarkivet A:2002:Persson;

    Sammanfattning : Accelerator mass spectrometry (AMS) is a highly sensitive method for counting atoms and it is used for detecting very low concentrations of both radionuclides and stable isotopes in small samples. The two major advantages of the AMS method are that the required amount of sample material is very small, but also that the efficiency is rather high, it takes less than an hour to analyse a sample.

    Författare :Achim Klüppelberg; Per Högselius; Kati Lindström; Anna Storm; Melanie Arndt; KTH; []
    Nyckelord :HUMANIORA; HUMANITIES; Nuclear power; water; technocratic culture; USSR; energy system; hydro-nuclear entanglements; Atomkraft; Wasser; technokratische Kultur; Sowjetunion; Energiesystem; hydronukleare Verflechtungen; Kärnkraft; vatten; teknokratisk kultur; Sovjetunionen; energisystem; hydronukleära sammanflätningar; History of Science; Technology and Environment; Historiska studier av teknik; vetenskap och miljö;

    Sammanfattning : After the development of nuclear weapons, civil applications were seen as a way through which protagonists of Soviet modernity could embrace a new future, which Josephson called atomic-powered communism. Where hydro-powered communism had reached its boundaries, nuclear energy was to take over. LÄS MER

  5. 4. Household salt as an emergency radiation dosemeter for retrospective dose assessments using optically stimulated luminescence

    Författare :Maria Christiansson; Malmö Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Optically stimulated luminescence OSL ; household salt; NaCl; retrospective dosimetry; accident dosimetry;

    Sammanfattning : In the event of a radiation accident, it is crucial to make rapid estimates of the absorbed dose received by both emergency workers, so-called first responders, and members of the public. Today, only personnel in rescue teams responding to nuclear emergencies have access to individual dosemeters. LÄS MER
