We are interested in factors affecting the sensitivity of eukaryotic cells to ionising radiation. We work with various cell types that we irradiate with different doses and dose rates of ionising radiation. We have sources for both low and high-LET radiation. We analyse cytogenetic effects (chromosomal aberrations and micronuclei), DNA repair (γH2AX foci-kinetics, comet assay) and cell survival. In addition, we are also interested in the mechanisms underlying individual radiosensitivity and methods of biological dosimetry.
