  1. 11. Speciation and Transport of Radionuclides from the Chernobyl Accident within the Gideå Site

    Författare :Paul Carbol; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The transport and redistribution of radionuclides originating from the Chernobyl accident were studied within a 1 km2 area in the northeastern part of Sweden (the Gideå site). Physical and chemical speciation of the fallout radionuclides were investigated on water samples collected within the study site using techniques developed especially for this purpose. LÄS MER

  3. 12. Phenomenological and mechanistic modeling of melt-structure-water interactions in a light water reactor (LWR) severe accident

    Författare :Anh Bui Viet; KTH; []
    Nyckelord :;

    Sammanfattning : Severe accidents in light water reactors have been the fotalpoint of much research, performed in the last two decades,aimed at understarrding the inherent physical phenomena and toevaluate proposed accident management schemes for mitigatingthe consequences of such accidents. Severe accident progressionand consequences, av the reactor core overheats and melts, areintimately related to the interactions of the melt with coolant(water) and structures. LÄS MER

  4. 13. Risk from radionuclides: a frog's perspective : Accumulation of 137Cs in a riparian wetland, radiation doses, and effects on frogs and toads after low-dose rate exposure

    Författare :Karolina Stark; Nils Kautsky; Petra Wallberg; Torbjörn Nylén; Michael Gilek; Dennis Woodhead; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dose model; mass balance budget; overbank sedimentation; amphibian; phantom; thermoluminescence chip; radiosensitivity; DNA damage; Biology; Biologi;

    Sammanfattning : Threats from man-made radionuclides include waste issues, increasing number of power plants, underground bomb testing, nuclear weapons, and “dirty bombs”. Until recently the ionizing radiation protection system focused on protecting humans with an implied protection of biota. LÄS MER

  5. 14. Radioactive fall-out from the Chernobyl nuclear power plant accident in 1986 and cancer rates in Sweden, a 25-year follow up

    Författare :Hassan Alinaghizadeh; Robert Wålinder; Marina Taloyan; Gunnar Nilsson; Anders Ahlbom; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Occupational and Environmental Medicine; Arbets- och miljömedicin;

    Sammanfattning : Aim: The current research aimed to study the association between exposure to low-dose radiation fallout after the Chernobyl accident in 1986 and the incidence of cancer in Sweden.Methods: A nationwide study population, selecting information from nine counties out of 21 in Sweden for the period from 1980 – 2010.

  7. 15. Studies on energy expenditure in walking after stroke

    Författare :Anna Danielsson; Göteborgs universitet; []
    Nyckelord :Cerebrovascular accident; Energy expenditure; Rehabilitation; Walking;

    Sammanfattning : After stroke, altered movement pattern involves low walking speed and increased energy cost as compared to normal. Cardiovascular disease is common in the stroke population. Knowledge about the physiological demands of various training interventions is important for the planning of exercise. LÄS MER
