  1. 1. Development and Applications of some Radioanalytical Procedures: Analysis of β- and α-Emitting Radionuclides Using Radiometric and ICP-MS Detection Methods

    Författare :Henrik Ramebäck; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; diffusion; plutonium; 90Sr; curium; uranium; 99Tc; bentonite clay; analysis; UO2 fuel; leaching; americium; neptunium;

    Sammanfattning : Analyses of radionuclides are important in environmental monitoring and in research. However, as in the analysis of many other species, interferences may be a problem. In a-spectrometric detection, 238Pu interferes with 241Am, owing to their similar decay energies. LÄS MER

  3. 2. Determination of Sr-90 in environmental samples

    Författare :Ingvar Friberg; Chalmers tekniska högskola; []
    Nyckelord :90Sr; fission products; environment; 89Sr; leaching; Cherenkov radiation; solvent extraction; 90Y;

    Sammanfattning : .... LÄS MER

  5. 4. Radioanalytical chemistry in emergency preparedness

    Författare :Ulrika Nygren; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry of Interfaces; Gränsytors kemi;

    Sammanfattning : Radioactive nuclides present a potential health hazard due to the ionising radiation emitted during their decay. The release of large amounts of radioactive nuclides is of concern both for man and the environment. LÄS MER

  7. 5. Interception and storage of wet deposited radionuclides in crops : field experiments and modelling

    Författare :Stefan Bengtsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The emission of radionuclides into the atmosphere from various sources, such as nuclear power plant accidents and nuclear bomb explosions, can result in the interception and uptake of radionuclides by crops in the agricultural ecosystem. These radionuclides e.g. LÄS MER
