  4. 2. Nuclear structure studies in the vicinity of the doubly closed shell nuclei ¹³²Sn and ²⁰⁸Pb by means of beta and alpha decay

    Author : Peter Carlé; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Experimental data of neutron-rich even tin, antimony and tellurium nuclei studied in beta decay are presented. Some of these nuclei are differing from the doubly closed shell nucleus 132Sn in only a few nucleons. The alpha decay of astatine and polonium nuclei in the vicinity of the doubly closed shell nucleus 208Pb has also been studied. READ MORE

  5. 3. Radon in natural waters : Analytical Methods; Correlation to Environmental Parameters; Radiation Dose Estimation; and GIS Applications

    Abstract : Investigations of radon in natural water and its relation to physical and chemical parameters are outlined in this thesis. In particular, a method for measuring 222Rn in water at low concentrations (~20 mBq. READ MORE

  6. 4. The Prevalence of Radioactivity in a Number of Non-Nuclear Industries

    Author : Torbjörn Gäfvert; Lund Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kärnfysik; Nuclear physics; zircon; ceramics industry; thorium; TIG welding; waterworks; calcium chloride; dicalcium phosphate; phosphate industry; non-nuclear industries; TENORM; Natural radioactivity; NORM;

    Abstract : Four different non-nuclear industries have been investigated regarding the presence of radioactive elements, with the focus on natural radioactivity. The aim of the studies was to investigate the flow of radionuclides in the processes and/or to estimate doses to exposed workers. READ MORE

  7. 5. Activity concentrations of radionuclides in energy production from peat, wood chips and straw

    Author : Robert Hedvall; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Radionuclides; peat; wood; chips; straw; bioenergy; biomass; district heating; emission; Cs; Physics; Chernobyl; Radioactivity; Fysik; Technological sciences; Teknik; Fysicumarkivet A:1997:Hedvall;

    Abstract : In this thesis quantitative analyses of radionuclide concentrations in bioenergy fuels such as peat, wood chips and straw are presented. For comparison a brief description is included of radionuclide concentrations and radiation doses from other sources of power and also from some industrial applications. READ MORE
