As workers in interventional radiology belong to one of the most occupationally exposed groups, methods for sufficiently accurate quantification of their external exposure are sought. The objective of the authors' experiment was to investigate the relations between eye lens dose and Hp(10), Hp(3) or Hp(0.07) values measured with a conventional whole-body personal thermoluminescence dosemeter (TLD). Conditions of occupational exposure during common interventional procedures were simulated in laboratory. An anthropomorphic phantom represented a physician. The TLDs were fixed to the phantom in different locations that are common for purposes of personal dosimetry. In order to monitor the dose at the eye lens level during the exposures, a special thermoluminescence eye dosemeter was fixed to the phantom's temple. Correlations between doses measured with the whole-body and the eye dosemeters were found. There are indications that personnel in interventional radiology do not need to be unconditionally equipped with additional eye dosemeters, especially if an appropriate whole-body dosimetry system has been already put into practice.
由于介入放射学领域的工作人员属于职业暴露风险最高的群体之一，因此人们一直在寻找能够足够准确地量化其外部暴露剂量的方法。作者进行该实验的目的是研究使用传统的全身个人热释光剂量计（TLD）测量的眼晶状体剂量与Hp(10)、Hp(3)或Hp(0.07)值之间的关系。在实验室中模拟了常见介入操作过程中的职业暴露条件。一个人体模型代表一名医生。将TLD固定在人体模型上不同的、常用于个人剂量测定的位置。为了监测暴露期间眼晶状体水平的剂量，在人体模型的太阳穴处固定了一个特殊的热释光眼剂量计。发现了全身剂量计和眼剂量计测量的剂量之间的相关性。有迹象表明，介入放射学领域的工作人员无需无条件地配备额外的眼剂量计，特别是如果已经实施了合适的全身剂量测定系统。
