Abstract:
Objective To study and estimate the effective dose of interventional employees in the common cerebralvascular, cardiovascular and liver interventional diagnosis and treatment.Methods The absorbed doses of tissue or organ of anthropomorphic phantom in these three procedures were estimated by the anthropomorphic phantom experiment.The effective doses were calculated by the tissue weight factor which was given by International Commission on Radiological Protection publication 103.Results The effective doses to high, medium and low group were 24.0, 9.7,6.8 μSv for cerebralvascular interventional diagnosis and treatment, and 36.3, 29.3, 17.8 μSv for cardiovascular interventional diagnosis and treatment, and 23.9, 11.3, 5.5 μ Sv for liver interventional diagnosis and treatment, respectively.Conclusions The effective doses of high, medium and low group of interventional employees in cardiovascular interventional procedure are higher than those of cerebralvascular and liver interventional procedures.
