2. 1. Temporal and spatial variation of radiocaesium in moose (Alces alces) following the Chernobyl fallout in Sweden : analyses of data from long-term monitoring in two specific areas

   Author : Robert Weimer; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : In my thesis, I have analysed long-term monitoring data of ¹³⁷Cs activity concentrations in moose (Alces alces) from the two Swedish municipalities Heby and Gävle. These study areas are adjacent and dominated by managed coniferous forests. The percentage of farmland in Heby is 20% but only 4% in the Gävle area. READ MORE

   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

5. 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

6. 4. Malignancies in Sweden after the Chernobyl accident in 1986

   Author : Martin Tondel; Bodil Persson; Lennart Hardell; Bengt Järvholm; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Epidemiology; Environmental; Chernobyl; ionising radiation; geographical information systems GIS; 8-OHdG; Malignancies; Low dose; Dose-response; Latency; Causalty; Epidemiology; Epidemiologi;

   Abstract : On 26 April 1986 an accident occurred in the Chernobyl nuclear power plant resulting in the release of large amount of radionuclides. Almost five percent of the total released caesium-137 was deposited in Sweden. The incidence of malignancies in the most affected counties in Sweden was investigated in three epidemiological studies.
