Some activities of EURADOS Working Group 9 (WG9) are presently funded by the European Commission (CONRAD project). The objective of WG9 is to promote and co-ordinate research activities for the assessment of occupational exposures to staff at workplaces in interventional radiology (IR) and nuclear medicine. For some of these applications, the skin of the fingers is the limiting organ for individual monitoring of external radiation. Therefore, sub-group 1 of WG9 deals with the use of extremity dosemeters in medical radiation fields. The wide variety of radiation field characteristics present in a medical environment together with the difficulties in measuring a local dose that is representative for the maximum skin dose, usually with one single detector, makes it difficult to perform accurate extremity dosimetry. Sub-group 1 worked out a thorough literature review on extremity dosimetry issues in diagnostic and therapeutic nuclear medicine and positron emission tomography, interventional radiology and interventional cardiology and brachytherapy. Some studies showed that the annual dose limits could be exceeded if the required protection measures are not taken, especially in nuclear medicine. The continuous progress in new applications and techniques requires an important effort in radiation protection and training.
欧洲放射防护剂量学协会第9工作组（WG9）的一些活动目前由欧盟委员会资助（CONRAD项目）。WG9的目标是促进和协调研究活动，以评估介入放射学（IR）和核医学工作场所工作人员的职业照射情况。对于其中一些应用，手指皮肤是个人外照射监测的限制器官。因此，WG9的第1小组负责处理在医学辐射领域使用四肢剂量仪的问题。医学环境中存在的辐射场特征多种多样，而且通常用单个探测器测量代表最大皮肤剂量的局部剂量存在困难，这使得准确进行四肢剂量测定变得困难。第1小组针对诊断和治疗性核医学、正电子发射断层扫描、介入放射学、介入心脏病学和近距离放射治疗中的四肢剂量测定问题进行了全面的文献综述。一些研究表明，如果不采取必要的防护措施，尤其是在核医学中，年度剂量限值可能会被超过。新应用和新技术的不断进步需要在辐射防护和培训方面做出重大努力。
