Radiation exposure to hospital personnel during 41 cervical spine radiographs of 30 multiply injured patients was prospectively evaluated. A digital dosimeter was attached to the exposed torso of personnel applying upper extremity traction or managing the airway. Radiation exposure was measured during each radiograph. Any exposure of one or more milliroentgen was detectable. No radiograph resulted in a measurable radiation exposure. Multiple radiographs (up to five exposures) also did not register even the minimum recordable exposure, demonstrating that exposure is less than 1.0 mR per radiograph (P < .05). We conclude that hospital personnel, even those applying traction or managing the airway, are not at risk of significant radiation exposure at the time of cervical spine radiographs.
对30名多处受伤患者的41张颈椎X光片拍摄过程中医院工作人员所受辐射暴露进行了前瞻性评估。将数字剂量计附着于进行上肢牵引或气道管理的工作人员暴露的躯干上。在每次X光片拍摄期间测量辐射暴露。任何超过一毫伦琴的暴露都是可检测到的。没有一张X光片产生可测量的辐射暴露。多次X光片拍摄（多达五次曝光）也未记录到哪怕是最低可记录的暴露，表明每次X光片的暴露小于1.0毫伦琴（P < .05）。我们得出结论，医院工作人员，即使是那些进行牵引或气道管理的人员，在颈椎X光片拍摄时也没有受到显著辐射暴露的风险。
