The aim of this article was to explore the evidence for the revised European Union basic safety standard (BSS) radiation dose limits to the lens of the eye, in the context of medical occupational radiation exposures. Publications in the open literature have been reviewed in order to draw conclusions on the exposure profiles and doses received by medical radiation workers and to bring together the limited evidence for cataract development in medical occupationally exposed populations. The current status of relevant radiation-protection and monitoring practices and procedures is also considered. In conclusion, medical radiation workers do receive high doses in some circumstances, and thus working practices will be impacted by the new BSS. However, there is strong evidence to suggest that compliance with the new lower dose limits will be possible, although education and training of staff alongside effective use of personal protective equipment will be paramount. A number of suggested actions are given with the aim of assisting medical and associated radiation-protection professionals in understanding the requirements.
本文旨在探讨在医疗职业辐射暴露背景下，欧盟修订后的基本安全标准（BSS）对眼部晶状体辐射剂量限制的相关证据。对公开文献中的出版物进行了综述，以便就医疗辐射工作人员的暴露情况和所接受的剂量得出结论，并汇总医疗职业暴露人群中白内障形成的有限证据。还考虑了相关辐射防护和监测实践及程序的现状。总之，医疗辐射工作人员在某些情况下确实会接受高剂量辐射，因此新的BSS将对工作实践产生影响。然而，有充分证据表明，尽管对工作人员的教育和培训以及有效使用个人防护设备至关重要，但遵守新的较低剂量限制是可能的。给出了一些建议行动，旨在帮助医疗及相关辐射防护专业人员理解这些要求。
