  1. 1. Radiocesium in the forest and forest industry, Studies on the flow, occurrence and technological enhancement of radionuclides in the forest industry with emphasis on radiocesium

    Author : Aaro Ravila; Lund Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; forestry technology; forestry; recovery; Recycling; enhancement; fallout; radiocesium; wood; ash; biofuel; Silviculture; radiation.; Skogsvetenskap; skogsbruk; skogsteknik;

    Abstract : In the aftermath of the nuclear weapons testing and as compared with agriculture, the forest industry has received relatively little attention in spite of its large-scale use of radiocesium- contaminated wood and water. After the Chernobyl nuclear power plant accident in 1986, numerous studies of the forest environment have been conducted with respect to radionuclide transfer through the forest ecosystem or its many components.

    Abstract : 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. READ MORE

  3. 3. Studies of Long-lived Radionuclides in the Environment - with Emphasis on 99Tc, 237Np and Pu Isotopes

    Author : Patric Lindahl; Lund Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nuclear medicine; radiobiology; Nukleärmedicin; radiobiologi; atomic ratio; environmental samples; nuclear weapons fallout; Chernobyl fallout; bioindicators; activated carbon; Sellafield; plutonium; neptunium; ICP-MS; technetium;

    Abstract : Studies of the long-lived anthropogenic radionuclides 99Tc, 237Np, 239Pu and 240Pu were performed in marine and terrestrial areas contaminated by different accidental and controlled releases of radioactive materials. The three main sources discussed in this thesis are nuclear weapons tests, nuclear reprocessing plants and the Chernobyl accident. READ MORE

  5. 5. Anthropogenic Radionuclides in the Arctic Ocean: Distribution and Pathways

    Author : Dan Josefsson; Lund Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; americium; plutonium; iodine; strontium; cesium; Sellafield; Chernobyl; global fallout; currents; shelf; ocean; radioactivity; Arctic; Ecology; Ekologi;

    Abstract : Anthropogenic radionuclide concentrations have been determined in seawater and sediment samples collected in 1991, 1994 and 1996 in the Eurasian Arctic shelf and interior. Global fallout, releases from European reprocessing plants and the Chernobyl accident are identified as the three main sources. READ MORE
