Dosemeter results for ∼81 500 people performing fluoroscopic and interventional radiology procedures were examined to identify differences between groups monitored either by using two dosemeters, one placed at the collar above the apron and a second placed under the apron on the torso (EDE1) or by using one single dosemeter placed at the collar above the apron (EDE2). The median annual HE was 0.17 mSv for those monitored using the EDE1 protocol and 0.26 mSv for the group using the EDE2 protocol. The EDE2 method was used most frequently with the EDE1 method preferred for those more highly exposed. Approximately, 22 % of dosemeter results for EDE1 were inconsistent with expected norms based on over and under apron dosemeter relationships.
对约81500名进行荧光透视和介入放射学程序的人员的剂量计结果进行了检查，以确定两组之间的差异。一组使用两个剂量计进行监测，一个放在防护围裙上方的领口处，另一个放在躯干上防护围裙下方（EDE1）；另一组使用一个剂量计放在防护围裙上方的领口处（EDE2）。采用EDE1方案监测的人员年有效剂量中位数为0.17 mSv，采用EDE2方案的组为0.26 mSv。EDE2方法使用最为频繁，而对于暴露程度较高的人员则首选EDE1方法。基于围裙上下剂量计关系，EDE1的剂量计结果中约22%与预期标准不一致。
