    Sammanfattning : Nuclear power produces a large portion of the electricity worldwide. It has been the largest low-carbon energy source for more than 30 years and has played an essential role in the security of energy supplies for many countries. LÄS MER

  3. 12. Tellurium Behavior and Management in the Liquid Phases in the Containment During a Severe Nuclear Reactor Accident

    Författare :Anna-Elina Pasi; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; severe nuclear reactor accident; fission product; source term; tellurium;

    Sammanfattning : No industry is immune to accidents; however, the consequences and the probability are the parameters to consider when assessing the risks. When considering nuclear power, two of the highest-level accidents have occurred during the course of the commercial use of nuclear energy. LÄS MER

  4. 13. Long-term radiobiological effects of 131I exposure - dose, age and time related transcriptomatic and proteomic rasponse in rats

    Författare :Malin Larsson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiation; thyroid; plasma; late effects; biomarkers; transcript; protein;

    Sammanfattning : 131I is commonly used in the clinic for treating thyroid diseases, using the physiological uptake of iodine in thyroid, but also for other target tissues. 131I is also commonly released during nuclear accidents. LÄS MER

  5. 14. Studies on the Gamma Radiation Environment in Sweden with Special Reference to 137Cs

    Författare :Sara Almgren; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; gamma radiation; caesium; 137Cs; deposition; migration; precipitation; in situ; CDE; NWF; Chernobyl; soil sampling; field measurements; dose measurements; dose rate; TLD; natural radiation; Kriging;

    Sammanfattning : Gamma radiation in the environment today mainly originates from naturally occurring radionuclides, but anthropogenic radionuclides, such as 137Cs, contribute in some areas. In order to assess population exposure in case of fallout from nuclear weapons (NWF) or accidents, knowledge and monitoring of external gamma radiation and radionuclide concentrations in the environment is important.

  7. 15. Household salt as an emergency radiation dosemeter for retrospective dose assessments using optically stimulated luminescence

    Författare :Maria Christiansson; Malmö Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Optically stimulated luminescence OSL ; household salt; NaCl; retrospective dosimetry; accident dosimetry;

    Sammanfattning : In the event of a radiation accident, it is crucial to make rapid estimates of the absorbed dose received by both emergency workers, so-called first responders, and members of the public. Today, only personnel in rescue teams responding to nuclear emergencies have access to individual dosemeters. LÄS MER
