In a first clinical application study, recently introduced BeOSL Hp(3) dosemeters were used for cumulative workplace characterization measurements in interventional radiology and interventional neuroradiology. Eye lens doses were accumulated on dosemeters assigned to interventions in specific anatomical areas and shared by multiple physicians. Doses were measured inside and outside of radiation protection glasses in order to compare shielded and unshielded doses near the left eye of the operator. Dose values per intervention were in the range of 0.014 mSv–0.097 mSv with the highest doses in interventions performed on the anatomical areas of the spine, abdomen, and pelvis. Additionally, Hp(10) doses were recorded at the collar of the thyroid protector, which showed a limited correlation with eye lens doses. Dose reduction factors obtained for two types of radiation protection glasses were between 2.5 and 6 in accordance with previous static measurements in the laboratory. While no systematic extrapolation to annual doses based on actual annual numbers of interventions for individual physicians has been performed yet, a simple time-based extrapolation of the recorded doses suggests that unshielded eye lens doses can approach the annual limit of 20 mSv and underline the importance of the use of radiation protection glasses and dose monitoring.

BeOSL H p(3)剂量计在介入性血管造影和神经放射学中的眼镜剂量测定

在首次临床应用研究中,最近推出的BeOSL H p(3)剂量计用于介入放射学和介入神经放射学中的累积工作场所特征测量。眼镜片剂量累积在指定用于特定解剖区域干预的剂量计上,并由多位医生共享。在辐射防护眼镜的内部和外部测量剂量,以便比较操作员左眼附近的屏蔽剂量和非屏蔽剂量。每次干预的剂量值在0.014 mSv–0.097 mSv的范围内,在脊柱,腹部和骨盆的解剖区域进行的干预中剂量最高。另外,H p(10)在甲状腺保护器的衣领处记录了剂量,显示与眼镜镜片剂量的相关性有限。根据实验室先前的静态测量结果,两种防辐射玻璃的剂量减少系数在2.5至6之间。虽然尚未根据个别医生的实际年度干预次数对年度剂量进行系统的推断,但对记录的剂量进行简单的基于时间的推断表明,未屏蔽的眼镜片剂量可接近20 mSv的年度限值,并强调了重要性防辐射眼镜的使用和剂量监测。
