ABSTRACT
Objective To investigate the chromosomal aberrations in seven medical staffs suspected with exposure to ionizing radiation and to speculate its possible causation.Methods The hospital staffs,including 6 females and 1 male,worked in a clinical laboratory where a CT room was located downstairs.The thickness of precast slab between these two rooms was 6 cm.Peripheral blood lymphocytes of seven staffs were examined for conventional chromosomal aberrations.Results The frequencies of dicentrics in the peripheral lymphocytes of 4 females were from 0.40% to 1.60% that was significantly higher than the spontaneous frequency of dicentrics (0.03%,x2 =36.79,P < 0.05).The translocation was observed in the lymphocytes from all subjects with frequencies from 0.33% to 1.20%,obviously higher than its spontaneous frequency of 0.01% (x2 =42.90,P < 0.05).Conclusion These staffs suffer from ionizing radiation.
