Abstract Objective To investigate the operators' lens and finger radiation dose in interventional operation to get to know interventional radiology staff extremity radiation dose levels in Guangdong and to provide some reference data for giving relevant radiation protection requirements.Methods 2014.7-2015.3 20 interventional radiology staff in two comprehensive hospitals were selected as interviewees, who were issued 70 sets of rings and eye lens dosimeters (LiF (Mg, Cu, P)). 20 sets of dosimeters used to cumulative dose survey after wearing two months, while the others used to dose survey in different types single surgery.Results In 14 interventional cardiology staffs, the eye lens cumulative dose was up to 2.64 mSv, and hands dose was up to 11.61 mSv. 2 neurosurgery staffs survey results respectively while 2 TECA-based interventional surgical staffs were respectively 2.46 mSv, 29.33 mSv. The eye len and hand dose ranges in single surgical coronary angioraphy (CA) were respectively 0.11~0.27 mSv, 0.11~0.70 mSv; transluminal coronary angioplasty (PTCA) were respectively 0.04~0.31 mSv, 0.07~0.47 mSv; percutaneous coronary intervention (PCI) were respectively 0.10~1.49 mSv, 0.15~7.43 mSv; radiofrequency ablation (RFA) were respectively MDL~0.26 mSv, MDL~0.24 mSv.Conclusion According to this considerable workload, highest eye len annual dose levels were estimated roughly closer to international standard, suggesting that for surgical intervention personnel, to strengthen monitoring of the extremities and take protective measures are necessary.
