  1. 1. 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

  3. 2. Downward migration and transfer to plants of radiocaesium in Scottish soil profiles : a comparison with earlier studies

    University essay from SLU/Dept. of Soil and Environment

    Author : Kristin Thored; [2010]
    Keywords : Radiocaesium; migration rate; migration depth; transfer factors; deposition; Scotland;

    Abstract : Following the accident at the nuclear power plant in Chernobyl in 1986, great volumes of137Cs were distributed over large parts of the former Soviet Union and Europe. Over Scotland,radiocaesium was deposited as wet deposition. READ MORE

  4. 3. Uptake of 137Cs by fungi and plants due to potassium fertilization in Heby municipality in response to the Chernobyl nuclear accident

    University essay from SLU/Dept. of Soil and Environment

    Author : Therèse Nilsson; [2009]
    Keywords : Radiocaesium; 137Cs; potassium; potassium fertilization; forest plants; fungi; ; countermeasure; Chernobyl nuclear accident;

    Abstract : The fallout from the Chernobyl nuclear accident resulted in large deposits of caesium, iodine and strontium as well as noble gases in various parts of Sweden. 137Cs has a radioactive halflife of about 30 years and is therefore one of few radio-fission products remaining in measurable quantities in the Swedish soil.

  5. 4. The influence of soil properties on the transfer of 137Cs from soil to plant : results from a field study 21 years after the Chernobyl accident

    University essay from SLU/Dept. of Soil and Environment

    Author : Maja Larsson; [2008]
    Keywords : caesium; 137Cs; radioactive fallout; Chernobyl; field study; plant uptake; soil; soil-plant transfer;

    Abstract : 137Cs is one of a few radio contaminants from the Chernobyl accident in 1986 that is left in measurable quantities in Sweden. The hazardous radionuclide has a physical half-life of 30 years and enters easily into biological systems. Several studies have been performed on 137Cs and its behaviour in different ecosystems since the fallout. READ MORE

  6. 5. Migration of radiocaesium in six Swedish pasture soils after the Chernobyl accident : a comparison with earlier studies 1987-2005

    University essay from SLU/Dept. of Soil and Environment

    Author : Henning Persson; [2008]
    Keywords : radiocaesium; 137Cs; migration; migration depth; soil-plant transfer; Chernobyl fallout; field study; pasture soils;

    Abstract : This study comprises six pasture soils in central and northern Sweden which were strongly affected by the Chernobyl fallout in 1986. The aim of the study was to investigate the vertical migration and plant uptake of radiocaesium as related to soil texture and other soil properties. READ MORE
