  1. 1. The microdosimetric variance-covariance method used for beam quality characterization in radiation protection and radiation therapy

    University dissertation from Stockholm : Medicinsk strålningsfysik (tills m KI)

    Author : Jan Erik Lillhök; Stockholms universitet.; [2007]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ionizing radiation; radiation quality; radiation protection; radiation therapy; microdosimetry; nanodosimetry; variance-covariance method; MEDICINE Physiology and pharmacology Radiological research Radiological physics; MEDICIN Fysiologi och farmakologi Radiologisk forskning Radiofysik; medicinsk strålningsfysik; Medical Radiation Physics;

    Abstract : Radiation quality is described by the RBE (relative biological effectiveness) that varies with the ionizing ability of the radiation. Microdosimetric quantities describe distributions of energy imparted to small volumes and can be related to RBE. READ MORE

  2. 2. Radiobiological studies with low energy ionizing radiation - dosimetric aspects

    University dissertation from Lund University (Media-Tryck)

    Author : Gustav Grafström; Lund University.; Lunds universitet.; [2005]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; low energy; Radiobiology; dosimetry; cell model; Radiofarmaceutisk teknik; Radiopharmaceutical technology; radiobiologi; Nukleärmedicin; radiobiology; Nuclear medicine; animal model;

    Abstract : Background: During the last 20 years both in vitro and in vivo models have been developed for studies of the cell killing characteristics of low energy electrons, e.g. Auger electrons. This thesis deals with radiobiological effects of radiation from indium isotopes in V79 cells in vitro (Paper I-III) and the rat testis in vivo (Paper IVV). READ MORE

  3. 3. Role of MTH1 and MYH proteins in genotoxic effects of radiation

    University dissertation from Stockholm : Department of Molecular Biosciences, The Wenner-Gren Institute, Stockholm University

    Author : Sara Shakeri Manesh; Stockholms universitet.; [2015]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MTH1; MYH; gamma radiation; UV radiation; oxidative stress; low dose rate ionizing radiation; molekylärgenetik; Molecular Genetics;

    Abstract : Humans are constantly exposed to different types of radiations. It has been suggested that low dose and low dose rate of γ-radiation as well as ultra violet A (UVA) induce oxidative stress in cells that may promote mutations. READ MORE

  4. 4. Household salt as an emergency radiation dosemeter for retrospective dose assessments using optically stimulated luminescence

    University dissertation from Medical Radiation Physics, Lund University

    Author : Maria Christiansson; Lund University.; Lunds universitet.; [2014]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Optically stimulated luminescence OSL ; household salt; NaCl; retrospective dosimetry; accident dosimetry;

    Abstract : In the event of a radiation accident, it is crucial to make rapid estimates of the absorbed dose received by both emergency workers, so-called first responders, and members of the public. Today, only personnel in rescue teams responding to nuclear emergencies have access to individual dosemeters. READ MORE

  5. 5. Radiobiological effects of the thyroid gland - transcriptomic and proteomic responses to 131l and 211At exposure

    University dissertation from Göteborg : University of Gothenburg

    Author : Nils Rudqvist; Göteborgs universitet.; Gothenburg University.; [2015]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; astatine-211; iodine-131; radionuclide therapy; nuclear medicine; environmental exposure; thyroid; radiation biology; transcriptomics; proteomics; ionizing radiation; toxicity; normal tissue damage; microarray; LC-MS; biomarker;

    Abstract : Radionuclides are widely used in medicine. 131I is one of the most employed radionuclides and is administered to patients either bound to tumor targeting molecules or as halide to target the thyroid or thyroid cancer. READ MORE
