  1. 11. Factors modifying cellular response to ionizing radiation

    Författare :Lei Cheng; Andrzej Wojcik; Siamak Haghdoost; Lovisa Lundholm; Penelope A. Jeggo; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Radiation biology; DNA damage; gene expression; alpha particles; X-rays; mixed beams; gamma rays; hypothermia; dose rate.; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : Many physical factors influence the biological effect of exposure to ionizing radiation, including radiation quality, dose rate and temperature. This thesis focuses on how these factors influence the outcome of exposure and the mechanisms behind the cellular response. LÄS MER

  3. 12. Ionizing Radiation in Concrete and Concrete Buildings : Empirical Assessments

    Författare :Magnus Döse; Johan Silfwerbrand; Erik Sturkell; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggvetenskap; Civil and Architectural Engineering;

    Sammanfattning : One of the major issues with radiation from the natural isotopes 40K, 226Ra (238U) and 232Th and their decay products is the forthcoming legislation from the European Commission in relation to its Basic Safety Directive (2014). The European legislation is mandatory and could not be overthrown by national legislation. LÄS MER

  5. 14. New tools for probing biological extremes of ionizing radiation

    Författare :Charlotta Nilsson; Kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysicumarkivet A:000;

    Sammanfattning : Three different biological extremes of irradiation of living organisms, both human and animal, have been investigated and are presented in this thesis. Central to the thesis is the concept of bystander effects of ionizing radiation, i.e. LÄS MER

  7. 15. Neonatal Exposure to Low-Dose Ionizing Radiation in Mice : Developmental Neurotoxic Effects of Single and Fractionated Doses and Interaction with Nicotine

    Författare :Sonja Buratovic; Per Eriksson; Jack Valentin; Uppsala universitet; []
    Nyckelord :;

    Sammanfattning : This thesis aims to investigate the developmental neurotoxic effects of low-dose exposure to ionizing radiation, alone or together with nicotine, during a defined critical period of neonatal brain development in mice. Investigation of neurotoxic effects following fractionated or acute low-dose radiation, resembling the clinical situation during repeated CT scans or radiation delivered to non-target tissue during radiotherapy, and possible interaction effects with other agents, is of great importance for risk and safety evaluation.
