Abstract：
To determine the eye lens dose (3 mm dose equivalent [Hp(3)]) received by spine surgeons during myelography and evaluate the effectiveness of radiation-protective glasses and x-ray tube system positioning in reducing radiation exposure. This study included spine surgeons who performed myelography using over- or under-table x-ray tube systems. Hp(3) was measured for each examination using a radio-photoluminescence glass dosimeter (GD-352M) mounted on radiation-protective glass. This study identified significantly high Hp(3) levels, especially in the right eye lens in spinal surgeons. The median Hp(3) values in the right eye were 524 (391-719) and 58 (42-83)μSv/examination for over- and under-table x-ray tube systems, respectively. Further, Hp(3)AK, which was obtained by dividing the cumulative air kerma from Hp(3), was 8.09 (6.69-10.21) and 5.11 (4.06-6.31)μSv mGy-1for the over- and under-table x-ray tube systems, respectively. Implementing radiation-protective glasses resulted in dose reduction rates of 54% (50%-57%) and 54% (51%-60%) for the over- and under-table x-ray tube systems, respectively. The use of radiation protection glasses significantly reduced the radiation dose in the eye lens during myelography, with the most effective measures being the combination of using radiation protection glasses and an under-table x-ray tube system.
摘要：
确定脊柱外科医生在脊髓造影期间接受的眼晶状体剂量（3mm剂量当量[Hp（3）]），并评估防辐射眼镜和X射线管系统定位在减少辐射暴露方面的有效性。这项研究包括使用台式或台式X射线管系统进行脊髓造影的脊柱外科医生。使用安装在防辐射玻璃上的放射性光致发光玻璃剂量计(GD-352M)测量每次检查的Hp(3)。这项研究确定了显著高的Hp(3)水平，尤其是在脊柱外科医生的右眼晶状体中。对于表上和表下的X射线管系统，右眼的中位Hp（3）值分别为524（391-719）和58（42-83）μSv/检查，分别。Further,Hp(3)AK,它是通过将累积空气角值除以Hp(3)获得的，对于表上和表下的X射线管系统，分别为8.09（6.69-10.21）和5.11（4.06-6.31）μSvmGy-1，分别。实施防辐射眼镜的剂量减少率分别为54％（50％-57％）和54％（51％-60％）的表上下X射线管系统，分别。辐射防护眼镜的使用显着减少了脊髓造影期间眼睛晶状体中的辐射剂量，最有效的措施是结合使用辐射防护眼镜和台下X射线管系统。
