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.

Cytogenetic and molecular effects following exposure to ionizing radiation under various in vitro co

The health effects associated with exposure to natural and medical sources of radiation are not fully understood.

Cytogenetic methods in biological dosimetry

Biological dosimetry is a method that allows to estimate the dose of ionising radiation based on the frequency of aberrations in peripheral blood lymphocytes of an accident victim.

Searching for markers of individual sensitivity to ionising radiation

The results of several studies indicate that an enhanced radiation sensitivity of human peripheral blood lymphocytes (PBL) may be associated with an enhanced risk of developing cancer.
