  1. 1. 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

  3. 2. Exploring long-term trends in hypoxia (oxygen depletion) in Western Gotland Basin, the Baltic Sea

    University essay from Lunds universitet/Geologiska institutionen

    Author : Tianzhuo Liu; [2012]
    Keywords : Baltic Sea; hypoxia; lead analysis; lamination; mineral magnetism; loss on ignition; magnetotactic bacteria; Östersjön; hypoxi; bly analys; laminering; glödgningsförlust; magnetotactic bakterier; Earth and Environmental Sciences;

    Abstract : Övergödningen är ett av de största hoten mot Östersjöns miljö. Den orsakar inte bara algblomning under sommarhalvåret utan även syrebrist (hypoxi). Utbredningen av syrefria bottnar i Östersjön har ökat fyrfaldigt sedan 1960-talet till följd av ökade utsläpp av näringsämnen, så som fosfor och kväve. READ MORE

  4. 3. Exploration of age offset between radiocarbon dating and dendrochronology

    University essay from Lunds universitet/Fysiska institutionen

    Author : Ayaz Khan; [2011]
    Keywords : Radiocarbon dating; Dendrochronology; AMS; Radiocarbon calibration; wiggle matching; Physics and Astronomy;

    Abstract : Populärvetenskaplig sammanfattning Koll av datering med kol 14 och trädringar Kol deltar i allt liv som vi känner det. Kolisotopen 14C med masstalet 14 bildas ständigt genom den kosmiska strålningens växelverkan med jordens atmosfär. READ MORE

  5. 4. AMS on the actinides in spent nuclear fuel : a study on a technique for inventory measurements

    University essay from Tillämpad kärnfysik

    Author : Niklas Lundkvist; [2010]
    Keywords : AMS; actinides; spent; nuclear; fuel;

    Abstract : This report is concerned with the question whether Accelerator mass spectrometry (AMS) is asuitable technique for measuring actinide inventory in spent nuclear fuel, and if it is better thanpresent techniques for these measurements. AMS is a kind of Mass spectrometry (MS) and has alot of applications where radio carbon dating is one of the most common. READ MORE

  6. 5. OCCUPATIONAL EXPOSURE of 14C a systematic investigation of 14C contamination of workers at the nuclear power industry, the pharmaceutical industry and other laboratories using 14C

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Carl-Magnus Nilsson; [2008]
    Keywords : Nukleärmedicin; Medicine and Health Sciences;

    Abstract : With the help from accelerator mass spectrometry (AMS), hair from workers within the nuclear power industry, pharmaceutical and biotechnology industry has been investigated to see if contamination from 14C. 14C-using companies and nuclear power plants were contacted, volunteers were recruited, who sent in hair samples together with a questionnaire.
