  1. 1. Can blue mussel shells be used for retrospective 14C-analysis in the marine environment of nuclear power plants?

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

    Author : Sofia Bjarheim; [2024]
    Keywords : Radionuclide; Marine Environment; Blue Mussels; 14C; Nuclear Power Plant; Physics and Astronomy;

    Abstract : Carbon-14 (14C) is one of the most important contributors to the collective effective dose of the public due to radioactive releases from nuclear power plants. However, the discharge of 14C from nuclear power plants (NPPs) into water has not been measured previously. READ MORE

  3. 2. Katters välfärd under behandling av hypertyreos : en enkätstudie

    University essay from SLU/Dept. of Clinical Sciences

    Author : Michelle Ciesluk; Rebecca Legge; [2023]
    Keywords : hypertyreos; jodfattigt foder; katt; medicinsk behandling; omvårdnadsåtgärder; radioaktiv jod; symtom; välfärd;

    Abstract : Hypertyreos är den vanligaste endokrina sjukdomen hos katter. Sjukdomen beror på sjukliga förändringar i tyreoidea som leder till en ökning av tyreoideahormon och en ökad ämnesomsättning. READ MORE

  4. 3. Environmental radiation measurements at Barsebäck nuclear power plant during the decommissioning phase

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Patrik Dahlström; [2022]
    Keywords : Medicine and Health Sciences;

    Abstract : Background and aim: The Barsebäck nuclear power plant (NPP) units ceased operations in 1999 and 2005. Now the NPP is in the phase of decommissioning, which is a complicated process that will take many years to complete. Radiological characterization of the surrounding area is a part of the decommissioning process. READ MORE

  5. 4. Calculating Minimum Detectable Activity for a moving scintillator detector using real-time speed measurement : Implementing a monitoring system to improve accuracy of surface contamination measurement systems

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Artur Amcoff; Oscar Persson; [2021]
    Keywords : Minimum Detectable Activity MDA ; Surface contamination; ISO 11929; Alpha α radiation; Beta β radiation; Detection limit; Counting efficiency; Minsta detekterbara aktivitet; Ytkontaminering; ISO 11929; Alfa α strålning; Beta β strålning; Detektionsgräns; Radioaktiv mäteffektivitet;

    Abstract : Surface contamination occurs in nuclear facilities, something that is important to detect easily and efficiently. Using today’s methods to detect nuclear surface contamination may cause certain inconsistencies as the human operator is solely trusted to keep the detector at the correct distance and move it at the correct speed.

  6. 5. Challenges in food system development for deep space missions

    University essay from SLU/Department of Molecular Sciences

    Author : Tor Blomqvist; [2020]
    Keywords : space food; deep space; microgravity; Mars; space food systems; bioregenerative food systems; food processing;

    Abstract : With a reinvigoration of space travel, space agencies around the world collaborate to land the first woman and the next man on the moon by 2024, establish a moonbase with a constant human lunar presence by 2028 and bring humans to Mars by 2030. Even though we may have the technology to bring humans to Mars, we do not have the required food systems and the food technology to sustain them. READ MORE
