  1. 6. On-line Mobile in situ Gamma Spectrometry

    University dissertation from Radiation Physics, Lund

    Author : Thomas Hjerpe; [2004]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiobiologi; Kärnfysik; Nuclear physics; radiation protection.; 137Cs; peak-to-valley method; depth distribution; orphan source search; orphan sources; emergency preparedness; mobile gamma spectrometry; nuclear accidents; Nuclear medicine; radiobiology; Nukleärmedicin;

    Abstract : Mobile in situ gamma spectrometry is an important instrument in the emergency preparedness for nuclear accidents. This work contributes through the development of strategies and analysis methods for two applications: an on-line search for gamma-emitting orphan sources and on-line estimation of the depth distribution of 137Cs.

  2. 7. Radiation exposure of human populations in villages in Russia and Belarus affected by fallout from the Chernobyl reactor

    University dissertation from Medical Radiation Physics, Lund University

    Author : Christian Bernhardsson; [2011]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chernobyl; caesium; effective dose; OSL; NaCl; TL; LiF; radiation protection survey instruments; deposition variability; long-term series;

    Abstract : A quarter of a century has elapsed since the catastrophe at the nuclear power plant in Chernobyl. The radioactive fallout affected all the European countries and most severely the three countries of Belarus, Russia and Ukraine. READ MORE

  3. 8. Characterizing and modulating the effects of ionizing radiation to the juvenile hippocampus

    University dissertation from Göteborg : University of Gothenburg

    Author : Malin Blomstrand; Göteborgs universitet.; Gothenburg University.; [2014]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; low-dose radiation; CNS; hippocampus; apoptosis; cytokines; growth factors; microglia; medulloblastoma; hippocampal sparing; tumor bed boost; cognitive risk estimation;

    Abstract : Survival rates after childhood cancer treatment have improved, leading to a growing population of survivors. Radiotherapy is an important tool for curing cancer in the brain. Unfortunately, radiotherapy is associated with late side effects e.g. READ MORE

  4. 9. Cellular responses to combined irradiation with alpha particles and X-rays

    University dissertation from Göteborg : University of Gothenburg

    Author : Alice Sollazzo; Andrzej Wojcik; Alexandros Georgakilas; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Radiation; DNA damage; mutations; alpha particles; X-rays; mixed beam; molekylär biovetenskap; Molecular Bioscience;

    Abstract : Mixed radiation fields, where different ionizing particles act together, are very important in radiobiology and in radiation protection. Mixed beams are not only the most common form of radiation exposure, but the prediction of their biological effect is also full of uncertainties. READ MORE

  5. 10. Maxillofacial cone beam computed tomography (CBCT) : : aspetcs on optimisation

    University dissertation from Malmö University, Faculty of Odontology

    Author : Ayman Al-Okshi; Malmö University.; Malmö University.; [2017]

    Abstract : Inom odontologisk såväl som inom medicinsk radiologi sker en snabb utveckling av nya tekniker. Nya metoder för att kunna diagnosticera och följa sjukdomsförlopp över tid introduceras. Cone-Beam Computed Tomography (CBCT) är en sådan ny teknik, som introducerades inom odontologin under sent 1990-tal. READ MORE
