Purpose: The purpose of this study was to prospectively measure the level of radiation exposure among nursing staff during interventional radiology procedures.<BR>Methods: All interventional radiology procedures performed at our institution between April 20 and June 19, 2009 were included in this study.<BR> Radiation exposure was measured as the equivalent dose penetrating tissue to a depth of 10mm using electronic personal dosimeters attached outside (Ha) and inside (Hb) lead aprons. Effective dose (HE) was estimated by calculating from Ha and Hb.<BR>Results: In total, data from 68 procedures were included in this study. Four nurses performed 71 nursing cares. The mean Ha was 0.70±1.0μSv, while the mean Hb was 0.06±0.2μSv. The mean HE was 0.14±0.3μSv.<BR>Conclusion: The present findings indicate that during interventional radiology procedures, nurses were exposed to very low levels of radiation.
