Low dose/low dose rate exposure to ionizing radiation and its potential risks
Low doses delivered at low dose rates are of particular concern, since nearly all exposure relevant to radiation protection is delivered in such a way. The information available is based on epidemiology, animal experiments, cellular studies and microdosimetric biophysical models. The presentation discusses the contribution of different sources to the exposure of workers and the public, and reviews the new risks involved when making an assessment based on the epidemiological data of the atomic bomb survivors. The extrapolation of these data (obtained at high doses/high dose rates) must be done on the basis of biophysical models supplemented by experimental studies, and the reliability of these data and models is therefore discussed. Finally, the risks of radiation exposure are compared with those from other agents under normal and occupational situations, and the concepts which could affect such comparisons are considered.
