  1. 1. Studies on the Gamma Radiation Environment in Sweden with Special Reference to 137Cs

    University dissertation from Göteborg

    Author : Sara Almgren; Göteborgs universitet.; Gothenburg University.; Göteborgs universitet.; Gothenburg University.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; gamma radiation; caesium; 137Cs; deposition; migration; precipitation; in situ; CDE; NWF; Chernobyl; soil sampling; field measurements; dose measurements; dose rate; TLD; natural radiation; Kriging;

    Abstract : Gamma radiation in the environment today mainly originates from naturally occurring radionuclides, but anthropogenic radionuclides, such as 137Cs, contribute in some areas. In order to assess population exposure in case of fallout from nuclear weapons (NWF) or accidents, knowledge and monitoring of external gamma radiation and radionuclide concentrations in the environment is important.

  2. 2. Systemic effects after ionizing radiation exposure: Genome-wide transcriptional analysis of mouse normal tissues exposed to (211)At, (131)I, or 4 MV photon beam

    University dissertation from Göteborg : Chalmers University of Technology

    Author : Britta Langen; Göteborgs universitet.; Gothenburg University.; Göteborgs universitet.; Gothenburg University.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; microarray; radiogenomics; systemic effects; biomarker; radionuclide therapy;

    Abstract : The radionuclides 131I and 211At are used or proposed for a variety of cancer treatments. Both radiohalogens exhibit considerable uptake in the thyroid gland and–to a lower degree–in various other tissues if they are unbound or released from a cancer-targeting agent. READ MORE

  3. 3. Optical Levitation of Charged Droplets

    University dissertation from Göteborg : Chalmers University of Technology

    Author : Oscar Isaksson; [2014]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; water; Optical manipulation; neutralization; Radiation Pressure; demonstration; Millikan Oil Drop experiment; evaporation;

    Abstract : The development of an experimental system used to investigate charged droplets is presented. The experimental setup combines optical levitation with Millikan's classical oil drop experiment and has also been used as a mean to demonstrate fundamental physical phenomena. READ MORE

  4. 4. Optical Studies For Synchrotron Radiation Beamlines

    University dissertation from MAX IV Laboratory, Lund University

    Author : Walan Grizolli; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Synchrotron Radiation; Optics; X-ray Optics; Beamline; Polarimetry; Coherence; Storage Rings; Diffraction Limited Storage Rings;

    Abstract : Popular Abstract in English Among the large variety of experiments performed in science, a common one is to pass a light beam through a sample, the object to be studied, and to study the outcomes of the light-sample interaction. Many light sources have been used for this purpose, like light bulbs and lasers. READ MORE

  5. 5. Modern Computational Physical Chemistry An Introduction to Biomolecular Radiation Damage and Phototoxicity

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Jorge Llano; Uppsala universitet.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; statistical mechanics; biophysical chemistry; interface; surface thermodynamics; bioelectrochemistry; ionizing radiation; radiation therapy; condensed matter; computational chemistry; nucleic acids; radiation damage; electrode potential; electronic transport; photochemistry; strand break; photodynamic action; cytostatic; solvation; solvated electron; absolute potential; chemical potential; Biologi; NATURAL SCIENCES Biology; NATURVETENSKAP Biologi;

    Abstract : The realm of molecular physical chemistry ranges from the structure of matter and the fundamental atomic and molecular interactions to the macroscopic properties and processes arising from the average microscopic behaviour.Herein, the conventional electrodic problem is recast into the simpler molecular problem of finding the electrochemical, real chemical, and chemical potentials of the species involved in redox half-reactions.
