This study investigated occupational characteristics and radiation exposure among radiologic technologists assisting fluoroscopically guided interventional (FGI) procedures. A nationwide survey of radiologic technologists in South Korea was conducted. Among 8058 male respondents, 664 (8.2%) assisted FGI procedures. The survey data were linked with dosimetry data from the National Dose Registry. Most radiologic technologists assisting FGI procedures were 30-40 years old and employed by general hospitals. These technologists worked in closer proximity to patients during procedures, less frequently used shield screens, more commonly utilized protective devices, and less commonly wore badge dosemeters than the ones not assisting FGI procedures. The average annual effective dose did not differ according to the performance of FGI procedures. The average cumulative effective dose among radiologic technologists assisting FGI procedures was significantly greater for those who had recently entered the field and personnel in rural areas than for those who did not assist these procedures.
本研究调查了在荧光透视引导介入（FGI）程序中协助操作的放射技师的职业特征和辐射暴露情况。在韩国对放射技师进行了一项全国性调查。在8058名男性受访者中，有664人（8.2%）协助进行FGI程序。调查数据与国家剂量登记处的剂量测定数据相关联。大多数协助FGI程序的放射技师年龄在30至40岁之间，受雇于综合医院。与不协助FGI程序的技师相比，这些技师在操作过程中与患者的距离更近，较少使用屏蔽屏，更常使用防护设备，且较少佩戴剂量计徽章。根据FGI程序的执行情况，平均年有效剂量没有差异。与不协助这些程序的人员相比，最近进入该领域的人员以及农村地区协助FGI程序的放射技师的平均累积有效剂量明显更高。
