11. 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.

12. New techniques in liver surgery
Sammanfattning : The development of liver surgery has a long history and through the years, much knowledge has been gathered concerning various aspects of the liver. The exploration and understanding of liver anatomy and liver regeneration and development of surgical techniques are important landmarks. LÄS MER
13. Malignancies in Sweden after the Chernobyl accident in 1986
Sammanfattning : On 26 April 1986 an accident occurred in the Chernobyl nuclear power plant resulting in the release of large amount of radionuclides. Almost five percent of the total released caesium-137 was deposited in Sweden. The incidence of malignancies in the most affected counties in Sweden was investigated in three epidemiological studies.

14. Radiographic quality workflow : in the digitized healthcare environment
Sammanfattning : This thesis emphasizes two different aspects — how radiographers use knowledge in image production work and perceive a radiographic quality workflow in the digitized healthcare environment using PACS — both because these aspects are cornerstones in the delivery of radiographic work and because the two aspects are related to one another. The aim was to inform the field of radiography of changes related to digital imaging production work by understanding how radiographers use their knowledge in work and perceive a radiographic quality workflow in detail.
