Title: Ionizing Radiation – what is the risk of cancer at low doses?

Abstract: There exists a vast number of studies of biological effects of ionizing radiation, mostly dedicated to radiation-induced cancers. Whereas the field of early effects is quite well understood, the low doses (below, say, 100 mGy) that may at best create only late or very late delatorious effects are a subject of on-going research. Estimation of a cancer risk for low doses or ionizing radiation requires universal biology-based model taking into account essential processes that take place in irradiated cells. I will try to present a relatively simple approach which can show what could be expected for the dose-effect dependence in the colony of cells as well as theoretical background of this subject.
