Description
Summary:The results are presented of chromosomal aberration analyses in blood lymphocytes sampled soon after the Chernobyl accident from children resident in and near Bragin, evacuees from the 30 km exclusion zone and a control group in Minsk. Children from the contaminated areas showed significantly elevated levels of dicentric aberrations. Average estimates of whole-body doses have been made by reference to an in vitro gamma dose effect curve. They were 230 mGy from Bragin children, and 400 mGy for evacuees and both are substantially higher than those derived from physical reconstructions. The difference may be due to their early incorporation of short-lived radionuclides.
