  1. 1. ESTIMATION OF RADIATION EXPOSURE FROM NATURALLY OCCURRING RADIONUCLIDES IN FOOD AND FOODSTUFF

    Master-uppsats,

    Författare :Ida Bengtsson; [2022-01-13]
    Nyckelord :Medical physics; Naturally occurring radionuclides; committed effective dose from ingested radionuclides; Biokinetic models;

    Sammanfattning : Purpose: The main purpose of this study was to provide an estimation of the committed effective dose received by the Swedish population from naturally occurring radionuclides (NORM) in the diet. This study was also aiming to investigate the impact on the committed effective dose due to the new developments in the biokinetic model for Po 210 . LÄS MER

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

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Patrik Dahlström; [2022]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : 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. LÄS MER

  4. 3. Development of methods for detection of radioactive aerosols of special importance for the ESS facility

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Martin Carlström; [2021]
    Nyckelord :alpha spectrometry; radioactive aerosols; spectrum simulation;

    Sammanfattning : With the construction of the European Spallation Source (ESS) steadily approaching the operational phase, an environmental monitoring program will soon be implemented with the purpose of monitoring emissions. With regard to radiation safety, it is highly important to monitor alpha emitting radionuclides in aerosol form. LÄS MER

  5. 4. Antropocen : vad, när och hur?

    Kandidat-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Benoit Hebrard; [2018]
    Nyckelord :the Antropocene; GSSP; marker; microplastics; artificial radionuclides; Earth and Environmental Sciences;

    Sammanfattning : The term Anthropocene has begun to be used to emphasize that conditions on Earth are governed by human activity and not by natural processes, as in the Holocene. However, the Anthropocene is not yet fully defined, neither temporally nor stratigraphically. LÄS MER

  7. 5. Critical Assessment of the Mineralogical Collections at Uppsala University using Raman Spectroscopy

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Yuliya Zhuk; [2017]
    Nyckelord :Raman spectroscopy; gemmology; geology; mineralogy; Mineralogical Collectio; Ramanspektroskopi; gemologi; geologi; mineralogi; mineralogisk samling;

    Sammanfattning : The technique of Raman spectroscopy was applied in order to identify and characterize the number of minerals in the mineralogical collection at the Department of Earth Sciences. The collection was broadened with five rare carbonates borrowed from the collection of the Swedish Museum of Natural History in Stockholm. LÄS MER
