  1. 1. Models for estimating radiation dose and LAR from radioactive fallout: extended dose algorithms for the computational tool LARCalc

    University essay from

    Author : Jonathan Sundström; [2022-09-09]
    Keywords : Medical physics; Nuclear power plant; Radiation dose; Effective dose; Lifetime attributable risk; LAR; Fallout; Inhalation; Strontium-90; Iodine-131; Cloudshine;

    Abstract : Today, emergency preparedness is needed against both nuclear reactor accidents and nuclear weapons fallout. Both scenarios can lead to exposure of ionizing radiation. Upon exposure, radionuclides will incur a radiation dose both internally and externally. READ MORE

  3. 2. Trace element analysis based on neutron activation with coincident gamma ray detection

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

    Author : Jessica Delgado; [2017]
    Keywords : scintillator detectors; gamma ray; gamma radiation; spectrometer; neutron activation analysis; trace element; Physics and Astronomy;

    Abstract : In this work, six soil samples have been analyzed. The samples come from different sedimentary layers on Earth. They were previously studied with the objective to find the trace concentration of iridium, to correlate the increased concentrations of iridium with meteorite impacts that have occurred on Earth.

  4. 3. Assessment of radionuclide content in waste barrels using the Canberra In-Situ Object Counting System (ISOCS)

    University essay from Lunds universitet/Sjukhusfysikerutbildningen; Lunds universitet/Medicinsk strålningsfysik, Lund

    Author : Marcus Persson; [2015]
    Keywords : Medicine and Health Sciences;

    Abstract : In order to store radioactive waste its contents need to be known. Determining radioactive waste can be achieved by different means. The most common method is using a detector to measure the gamma photons produced by the radionuclides in the waste. READ MORE

  5. 4. Uppfångning och kvarhållning av 134Cs och 85Sr i olika växtutvecklingsstadier

    University essay from SLU/Dept. of Soil and Environment

    Author : Anna-Lisa Mårtensson; [2012]
    Keywords : cesium; kvarhållning; LAI; motåtgärder; strontium; radioaktivitet; raps; uppfångning; vall; vete; växtutvecklingsstadier;

    Abstract : Emissions of radionuclides to the atmosphere can lead to wet deposition on plants in the event of rainfall. An increased level of radioactivity in the plants may occur due to interception and retention of the radionuclides. If the content of the plants is above the threshold limit value, entire yields may have to be destroyed. READ MORE

  6. 5. Överföring av radiocesium till potatis vid olika nedfallstidpunkter

    University essay from SLU/Dept. of Soil Sciences

    Author : Marielle Stenmark; [2008]
    Keywords : potatisknöl; potatisblast; 134Cs; artificiell deposition; radioaktivitet;

    Abstract : Agricultural land could be polluted by radioactive substances after a fallout. We would then need information about the level of contamination to decide whether the crops could be utilized as food under these circumstances. READ MORE
