  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. Construction of a carbon-14 bomb-pulse dating calibration curve relevant for man

    University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Sonny Nilsson; [2018]
    Keywords : Science General;

    Abstract : Radiocarbon dating of human tissues has great potential in medical applications. A consequence of the complex path of radiocarbon to humans through diet is that the radiocarbon content of samples from human subjects is not directly comparable with the atmosphere's. READ MORE

  4. 3. Bergsbrukets början, samt dess och jordbrukets påverkan på vegetationen uti Garpenbergs socken i sydöstra Dalarna

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Björn Karlsson; [2014]
    Keywords : Pollen; geokemi; bergsbruk; gruvbrytning; Garpenberg; Bergslagen; vegetationsförändringar; skog; jordbruk; pollen; geochemistry; mining; Sweden; vegetation changes; forest; farming;

    Abstract : Bergsbruket har under lång tid haft stor betydelse för Sverige både ekonomiskt och politiskt. Det har också haft en inverkan på naturmiljön bland annat genom huggningar för bränsle och utsläpp av tungmetaller. Ett av de områden i Sverige som är mest känt för sin metallhantering är Bergslagen. Idag är många gruvor nedlagda. READ MORE

  5. 4. Upgrade of the Graphitization System for 14C AMS Analyses

    University essay from Lunds universitet/Fysiska institutionen

    Author : Philip Dalsbecker; [2013]
    Keywords : 14C; AMS; Accelerator mass spectrometry; radiocarbon; vacuum; carbon-14; Physics and Astronomy;

    Abstract : For decades, accelerator mass spectrometry (AMS) has been used for radiocarbon dating. The background of this technique is outlined along with an in-depth look at the graphitization process used to prepare samples for AMS analysis. READ MORE

  6. 5. Holocene environmental changes as recorded in sediments from Kaggfjärden, southern archipelago of Stockholm, using diatom stratigraphy

    University essay from Institutionen för livsvetenskaper

    Author : Lena Ivarsson; [2011]
    Keywords : ;

    Abstract : Four sediment cores were sampled in Kaggfjärden, located in the southern archipelago of Stockholm. Two of the cores were analyzed with respect to the diatom record and lithology. Terrestrial macrofossils were dated using Carbon-14 dating. READ MORE
