  1. 11. Experimental determination of shielding factor for a Swedish farmhouse

    University essay from Lunds universitet/Fysiska institutionen

    Author : Mikael Westin; [2014]
    Keywords : Shielding factor Protection factor Location factor Fallout gamma radiation; Physics and Astronomy;

    Abstract : The protection that different types of buildings can provide against gamma radiation from radioactive fallout has been investigated since the late 1950s. The DCPA Standard Method has served as the basis to determine this protection, which is given by the so called “protection factor”. Several studies in the U.S. READ MORE

  3. 12. Radioktivt cesium (Cs-137) i vildsvin (Sus scrofa) från Tjernobyldrabbade områden i Sverige

    University essay from SLU/Dept. of Soil and Environment

    Author : Emilie Hallqvist; [2013]
    Keywords : Cs-137; vildsvin; vildsvinskött; Tjernobylolyckan; radioekologi; strålning;

    Abstract : In April 1986 an accident occurred at the nuclear power station in Chernobyl. Radionuclides were spread all over Europe including Sweden. Today there are still measurable concentrations of 137Cs in the different ecosystems in the contaminated parts of Sweden. READ MORE

  4. 13. Transfer of radiocaesium (137Cs) to lynx (Lynx lynx) and brown bear (Ursus arctos) in Chernobyl affected areas in Sweden

    University essay from SLU/Dept. of Soil and Environment

    Author : Yury Chaiko; [2012]
    Keywords : radiocaesium; lynx; brown bear;

    Abstract : In this study, 137Cs activity concentration was measured in 266 lynxes hunted in early spring during the years 2006-2011 in central and northern Sweden and in 161 bears hunted in the end of August until October during the years 2010 and 2011. Highest activity concentrations of 137Cs were observed in lynx and bear coming from counties with highest radiocaesium fallout after the Chernobyl accident. READ MORE

  5. 14. Studies of the transfer of radionuclides and dose rate assessments in the pasture lands located in the counties of Uppsala and Jämtland

    University essay from SLU/Dept. of Soil and Environment

    Author : Yosief Tesfatsion; [2012]
    Keywords : radionuclides; dose rate; transfer factor; migration; Chernobyl accident;

    Abstract : The study was conducted in the pastoral lands of two Counties, Uppsala and Jämtland Counties. Soil and grass samples were collected from six study areas. Two from Uppsala County: Lövstalöt and Möjsjövik, and four from Jämtland County: Backfors, Hallen, Myrviken and Vikdrolet. READ MORE

  6. 15. Activity concentration and transfer factors ofnatural and artificial radionuclides in the Swedishcounties of Uppsala and Jämtland

    University essay from SLU/Dept. of Soil and Environment

    Author : Nicola Pallavicini; [2011]
    Keywords : natural radionuclides; 137Cs; Transfer Factors;

    Abstract : The study was performed in two areas of Sweden respectively with high natural radioactivitybackground (County of Jämtland), and high 137Cs deposition area deriving from Chernobylfallout (County of Uppsala.Aims of the study were the calculation of activity concentration and transfer factors for all 6radionuclides in the two areas and analysis of influence of soil characteristics on radionuclidesbehavior.
