11. Cellular effects after exposure to mixed beams of ionizing radiation
Abstract : Mixed beams of ionizing radiation in our environment originate from space, the bedrock and our own houses. Radiotherapy patients treated with boron neutron capture therapy or with high energy photons are also exposed to mixed beams of gamma radiation and neutrons. READ MORE

12. Factors modifying cellular response to ionizing radiation
Abstract : 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. READ MORE

13. Formation and repair of complex DNA damage induced by ionizing radiation
Abstract : DNA is the critical target when cells are exposed to ionizing radiation, a potent stressor with capacity to produce complex DNA damages, thereby increasing the risk of cancer. DNA and associated histones form chromatin, which is an effective protection against ionizing radiation. READ MORE

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

15. Induction and repair of clustered DNA damage sites after exposure to ionizing radiation
Abstract : The mechanisms that maintain genomic stability safeguard cells from constant DNA damage produced by endogenous and external stressors. Therefore, this thesis aimed to specifically address questions regarding the requirement and involvement of DNA repair proteins in the repair of various types of radiation-induced DNA damage.
