目的：对于介入放射科医生和心脏科医生来说，评估手和眼睛的潜在剂量可能很困难。在文献中报道的剂量介入operators的研究进行了审查已carried.Methods：分布的工作人员剂量的相关部分的身体每单位剂量面积的产品和每一个程序在心脏病学的剂量进行了分析和平均值，中位数和四分位值。使用这些数据来提供可能的剂量水平的估计指导的可能性被认为是considered.Results：剂量指示值，可用于预测的数量级的剂量到眼睛，甲状腺和手从介入操作员的工作量已被派生，基于第三四分位值，从分析的剂量结果的分布。在审查保护和监测要求时，可以在风险评估中采用以这种方式进行的剂量估计。还审查了关于不同屏蔽和技术因素提供的保护的数据，以便为风险评估提供信息。关于剂量计佩戴位置的建议也应包括在风险评估中，因为使用次优剂量计进行的剂量测量可能会产生误导。
Objective: 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.Methods: 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.Results: 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.Conclusion: 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.
