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.
