Estimation of the effective doses for interventional employees in three common interventional diagnosis and treatment procedures

Objective: To study and estimate the effective dose of interventional employees in the common cerebral vascular, 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 cerebral vascular 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 cerebral vascular and liver interventional procedures.
