The purpose of this study was to measure staff radiation doses in representative institutions of five European countries performing coronary angiographies (CA) and percutaneous transluminal coronary angioplasties (PTCA), as well as to investigate any correlation with patient doses. Patient doses were recorded in terms of dose-area product (DAP). Staff doses were measured by thermoluminescence dosemeters placed on the operator's left shoulder and left foot. Radiation protection measures were also recorded. Third quartile shoulder and foot doses were 90 and 66 microSv in CA, and 157 and 173 microSv in PTCA, respectively. Shoulder dose was poorly correlated with DAP in CA (R2 = 0.29) and only moderately correlated in PTCA (R2 = 0.69). DAP and foot dose correlation was poor both in CA (R2 = 0.16) and in PTCA (R2 = 0.02). Protective measures taken by staff varied between countries, which may explain the poor correlation of patient and staff radiation doses.
本研究的目的是测量欧洲五个国家开展冠状动脉造影（CA）和经皮腔内冠状动脉成形术（PTCA）的代表性机构中工作人员的辐射剂量，并调查其与患者剂量之间的相关性。患者剂量以剂量面积乘积（DAP）记录。工作人员剂量通过放置在操作者左肩和左脚的热释光剂量计测量。还记录了辐射防护措施。CA中肩部和足部剂量的第三四分位数分别为90和66微希沃特，PTCA中分别为157和173微希沃特。CA中肩部剂量与DAP的相关性较差（R2 = 0.29），PTCA中仅为中度相关（R2 = 0.69）。CA（R2 = 0.16）和PTCA（R2 = 0.02）中DAP与足部剂量的相关性均较差。不同国家工作人员采取的防护措施各不相同，这可能解释了患者与工作人员辐射剂量相关性较差的原因。
