To understand the situation of radiation exposure to primary operators in the interventional X-ray procedures, a pilot survey was conducted for the 5 most frequently performed procedures in Shanghai in 2011. The distributions of entrance-surface air kerma (ESAK) were measured with thermoluminescent dosimeters (TLD) in 125 primary operators conducting the 5 procedures in 10 hospitals in Shanghai, and the equivalent doses (H-T) for eye lens and extremity as well as the effective dose (E) were estimated. The results showed that the mean ESAKs were usually larger than 10 mu Gy for unshielded eye lens and extremity in each procedure, and the annual H-T for unshielded eye lens exceeded 10 mSv in some procedures, such as the coronary angiography (CA) and angioplasty (PTCA). The mean annual effective doses were estimated to be 0.7-10.4 mSv among the 5 procedures, however, the values varied with different calculation algorithms.
