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.

不同类型围裙的背部辐射暴露

医生和护士在使用计算机时背对着 C 型臂荧光镜站立，从壁橱中取出东西并准备注射药物或干预器械。本研究旨在调查铅围裙的类型与使用 C 臂透视时医生和护士背部的辐射暴露之间的关系。我们比较了三组背部的辐射暴露：无铅围裙（C 组）、正面覆盖型（F 组）和环绕式（W 组）。另一条环绕式围裙被放在床上而不是病人身上。每次测量我们进行 40 次 C 臂透视。我们收集了床头柜、围裙上部和下部的空气比释动能（AK）、暴露时间（ET）和有效剂量（ED）。我们为每个位置测量了这些变量 30 次。F组，上部的ED最高（p＜0.001）。C组和F组下肢ED高于W组（p=0.012）。正面覆盖式围裙的辐射暴露高于环绕式，甚至颈部或甲状腺没有围裙。为了减少对医生或护士背部的辐射暴露，建议使用环绕式围裙。当医生转身离开患者或 C 臂透视时，这种类型的围裙可以减少背部的辐射。为了减少对医生或护士背部的辐射暴露，建议使用环绕式围裙。当医生转身离开患者或 C 臂透视时，这种类型的围裙可以减少背部的辐射。为了减少对医生或护士背部的辐射暴露，建议使用环绕式围裙。当医生转身离开患者或 C 臂透视时，这种类型的围裙可以减少背部的辐射。
