In preparation of a large European epidemiological study on the relation between eye lens dose and the occurrence of lens opacities, the European ELDO project focused on the development of practical methods to estimate retrospectively cumulative eye lens dose for interventional medical professionals exposed to radiation. The present paper applies one of the ELDO approaches, correlating eye lens dose to whole-body doses, to assess cumulative eye lens dose for 14 different Finnish interventional cardiologists for whom annual whole-body dose records were available for their entire working period. The estimated cumulative left and right eye lens dose ranged from 8 to 264 mSv and 6 to 225 mSv, respectively. In addition, calculations showed annual eye lens doses sometimes exceeding the new ICRP annual limit of 20 mSv. The work also highlights the large uncertainties associated with the application of such an approach proving the need for dedicated dosimetry systems in the routine monitoring of the eye lens dose.
在筹备一项关于眼晶状体剂量与晶状体混浊发生之间关系的大型欧洲流行病学研究时，欧洲ELDO项目专注于开发实用方法，以回顾性估计接触辐射的介入医疗专业人员的累积眼晶状体剂量。本文应用ELDO方法之一，即关联眼晶状体剂量与全身剂量，来评估14位不同的芬兰介入心脏病专家的累积眼晶状体剂量，这些专家在其整个工作期间都有年度全身剂量记录。估计的左、右眼晶状体累积剂量分别为8至264毫希沃特和6至225毫希沃特。此外，计算结果显示，年度眼晶状体剂量有时超过国际放射防护委员会（ICRP）新规定的20毫希沃特的年度限值。这项工作还凸显了应用此类方法存在的巨大不确定性，这证明在眼晶状体剂量的常规监测中需要专用的剂量测定系统。
