The aim is to estimate the possibility the new annual dose limit for eye lens to be exceeded and to study the impact of protective shield. Radiation exposure to medical personnel was evaluated with EDD-30 dosemeter in positions of operating surgeon, assisting doctor and nurse. At the operator's typical position for diagnosis and treatment of the urinary tract, the lens dose rates were 0.9 mSv h(-1) and 0.06 mSv h(-1) without and with lead shield. At the operator's position typical for percutaneous intervention dose rates were 1.9 and 0.02 mSv h(-1), respectively. At typical workload, the annual eye lens dose to the main operator without protective screen was estimated to be 29 mSv. With lead screen, operator lens dose can be reduced by a factor of 15-95 according to the procedure. Installation and use of lead screen and use of lead glasses were recommended to the endourology medical team.
目的是评估超过新的年度眼晶状体剂量限值的可能性，并研究防护屏蔽的影响。使用EDD - 30剂量计在主刀医生、助手医生和护士的位置对医务人员的辐射暴露进行评估。在泌尿外科医生进行诊断和治疗的典型位置，无铅屏蔽和有铅屏蔽时晶状体剂量率分别为0.9 mSv h⁻¹和0.06 mSv h⁻¹。在经皮介入的典型操作位置，剂量率分别为1.9 mSv h⁻¹和0.02 mSv h⁻¹。在典型工作量下，无防护屏时主操作人员的年度眼晶状体剂量估计为29 mSv。使用铅屏后，根据操作程序，操作人员的晶状体剂量可降低15至95倍。建议泌尿外科医疗团队安装和使用铅屏以及佩戴铅眼镜。
