Assessment of the potential doses to the hands and eyes for interventional radiologists and cardiologists can be difficult. A review of studies of doses to interventional operators reported in the literature has been undertaken.
Distributions for staff dose to relevant parts of the body per unit dose-area product and for doses per procedure in cardiology have been analysed and mean, median and quartile values derived. The possibility of using these data to provide guidance for estimation of likely dose levels is considered.
Dose indicator values that could be used to predict orders of magnitude of doses to the eye, thyroid and hands from interventional operator workloads have been derived, based on the third quartile values, from the distributions of dose results analysed.
Dose estimates made in this way could be employed in risk assessments when reviewing protection and monitoring requirements. Data on the protection provided by different shielding and technique factors have also been reviewed to provide information for risk assessments. Recommendations on the positions in which dosemeters are worn should also be included in risk assessments, as dose measurements from suboptimal dosemeter use can be misleading.
评估介入放射学家和心脏病学家手部和眼部的潜在剂量可能较为困难。为此，对文献中报道的介入操作人员剂量研究进行了回顾。
分析了单位剂量面积产物相关身体部位的工作人员剂量分布和心脏病学中的每次操作剂量，并得出了平均值、中位数和四分位数。还考虑了使用这些数据来提供估计可能剂量水平的指导。
根据分析的剂量结果分布，从第三四分位数值推导出了可以用于根据介入操作人员工作量预测眼部、甲状腺和手部剂量量级的剂量指示值。
当审查防护和监测要求时，可以使用这种方式进行剂量估算，并将其用于风险评估。还审查了不同屏蔽和技术因素提供的防护数据，以提供风险评估信息。还应在风险评估中包含剂量计佩戴位置的建议，因为使用不当的剂量计进行剂量测量可能会产生误导。
