    Sammanfattning : This study analyzes different views of science, technology and progress in popular science and science fiction published in Sweden during the 'long 1950s' (ca 1946-1964) and how they were related to youth. In the first part, popular technical periodicals are discussed - Teknikes Värld (Technical World) and Teknik för Alla (Technolvgy for Everyone). LÄS MER

  4. 3. Biomarkers of ionising radiation relevant to carcinogenesis : Dose, dose rate and LET dependency of the responses

    Sammanfattning : A better understanding of the relationship between ionising radiation (IR) dose, dose rate and radiation quality, and the risk of stochastic effects would improve risk extrapolation from atomic bomb survivors’ data. Owing to insufficient statistical power of epidemiological studies to detect excess incidence of cancer following low doses of IR delivered at low dose rates (LDLDR), as typically encountered in most common human exposure scenarios, radiobiological experiments are fundamental to describe the biological effectiveness of LDLDR and to define the underlying molecular mechanisms.

  5. 4. 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

  7. 5. On ionising radiation and breast cancer risk

    Författare :Anders Mattsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :ionising radiation; breast cancer induction; cancer induction; risk models; risk modification; pooled analysis; mammmographic screening; gained lost years of life;

    Sammanfattning : Background: It is well known that exposure to ionising radiation increases the risk for breast cancer occurrence. However, better understanding of breast cancer risks in terms of dose-response relationships formulated according to radiobiological target theories, age-at-exposure patterns and temporal dependence are important for the understanding of the underlying biological mechanism of radiation carcinogenesis as well as for the concern about possible risks associated with the very low doses received from routine mammographic screening.
