1. Cellular effects of ionizing radiation : Relevant for understanding cancer risk after medical and environmental radiation exposures
Abstract : Radiation-induced cancers are stochastic and delayed effects of exposure to ionizing radiation. The dose-response relationship for radiation-induced cancers at both low dose/low dose rates and high doses (doses encountered during radiotherapy) remains unclear. READ MORE

2. Accurate description of heterogeneous tumors for biologically optimized radiation therapy
Abstract : In this thesis, a model of tissue oxygenation is presented, that takes into account the heterogeneous nature of tumor vasculature. Even though the model is rather simple, the resulting oxygen distributions agree very well with clinically observed oxygen distributions for most tumors and healthy normal tissues. READ MORE

3. Optimizing experimental radioimmunotherapy : investigating the different mechanisms behind radiation induced cell deaths
Abstract : Background. Radiation therapy is an important treatment regimen for malignant disease. Radiation therapy uses ionizing radiation to induce DNA damage in tumor cells in order to kill them. READ MORE

4. Ethical aspects of radiation protection
Abstract : This aim of this thesis is to examine ethical aspects of radiation protection from ionizing radiation. Radiation protection is the professional field that deals with the protection of humans and the environment from the harmful effects of radiation. READ MORE

5. Radiation induced biomarkers of individual sensitivity to radiation therapy
Abstract : Fifty percent of solid cancers are treated with radiation therapy (RT). The dose used in RT is adjusted to the most sensitive individuals so that not more than 5% of the patients will have severe adverse healthy tissue effects. READ MORE
