Blood specimens were collected from 8 people 18 days after they had been accidentally exposed to a 947,2 GBq iridium192 source during industrial application. The equivalent whole-body dose received at day 0 was estimated using a model based on quantitative and qualitative chromosome aberration analysis in Iymphocytes. According to physical dose estimations, all 8 people were exposed to whole-body doses varyng from 12 mGy to 61 mGy. Substantiated evidence to this effect was found in at least 3 cases using biological dosimetric criteria, proving the sensitivity of this cytogenetic model even at low doses.
