1. The microdosimetric variance-covariance method used for beam quality characterization in radiation protection and radiation therapy
Abstract : Radiation quality is described by the RBE (relative biological effectiveness) that varies with the ionizing ability of the radiation. Microdosimetric quantities describe distributions of energy imparted to small volumes and can be related to RBE. READ MORE

2. Energy and intensity modulated radiation therapy with electrons
Abstract : In recent years intensity modulated radiation therapy with photons (xIMRT) has gained attention due to its ability to reduce the dose in the tissues close to the tumour volume. However, this technique also results in a large low dose volume. READ MORE

3. New tools for probing biological extremes of ionizing radiation
Abstract : Three different biological extremes of irradiation of living organisms, both human and animal, have been investigated and are presented in this thesis. Central to the thesis is the concept of bystander effects of ionizing radiation, i.e. READ MORE

4. Modeling and Characterization of nonlinear Materials for Protection of Optical Sensors
Abstract : This thesis concerns nonlinear materials and experimental techniques for optical power limiting applications. Theoretical models to analyze and simulate related measurements were studied. Two different numerical modeling tools for propagation of optical radiation through optically nonlinear media were developed. READ MORE

5. From Particle-Production Cross Sections to KERMA and Absorbed Dose for the Case 96 MeV n-12C Interactions
Abstract : Neutron-carbon interactions have been studied with a focus on charged-particle production of relevance to radiation protection and medical applications, such as cancer therapy. The measurements have been performed using the particle-detection setup, MEDLEY, and the 96 MeV neutron beam at the The Svedberg Laboratory in Uppsala. READ MORE
