Physicians and nurses stand with their back towards the C-arm fluoroscope when using the computer, taking things out of closets and preparing drugs for injection or instruments for intervention. This study was conducted to investigate the relationship between the type of lead apron and radiation exposure to the backs of physicians and nurses while using C-arm fluoroscopy. We compared radiation exposure to the back in the three groups: no lead apron (group C), front coverage type (group F) and wrap-around type (group W). The other wrap-around type apron was put on the bed instead of on a patient. We ran C-arm fluoroscopy 40 times for each measurement. We collected the air kerma (AK), exposure time (ET) and effective dose (ED) of the bedside table, upper part and lower part of apron. We measured these variables 30 times for each location. In group F, ED of the upper part was the highest (p < 0.001). ED of the lower part in group C and F was higher than that in group W (p = 0.012). The radiation exposure with a front coverage type apron is higher than that of the wrap-around type and even no apron at the neck or thyroid. For reducing radiation exposure to the back of physician or nurse, the wrap-around type apron is recommended. This type of apron can reduce radiation to the back when the physician turns away from the patient or C-arm fluoroscopy.
医生和护士在使用计算机时背对 C 型臂透视机，从壁橱中取出物品并准备注射药物或介入器械。本研究旨在探讨使用 C 型臂透视机时，医生和护士背部所受的铅围裙类型与辐射暴露之间的关系。我们比较了三组（无铅围裙组（C 组）、前覆盖型（F 组）和包裹型（W 组））背部的辐射暴露。另一种包裹式围裙被放在床上而不是病人身上。我们对每个测量组进行了 40 次 C 臂透视。我们收集了床头柜、围裙上半部分和下半部分的空气比释动能（AK）、曝光时间（ET）和有效剂量（ED）。我们在每个位置测量了这些变量 30 次。在前覆盖型组（F 组）中，上半部分的 ED 最高（p<0.001）。C 组和 F 组围裙下半部分的 ED 高于 W 组（p=0.012）。前覆盖型围裙的辐射暴露比包裹型围裙甚至无围裙在颈部或甲状腺处更高。为了减少医生或护士背部的辐射暴露，建议使用包裹型围裙。当医生背对病人或 C 型臂透视机时，这种围裙可以减少对背部的辐射。
