With regard to wider equipment safety considerations, there are many national and international standards for medical devices, whose intention is to ensure the safety of equipment in respect of, for example electrical, mechanical, and software hazards. This report is not intended to duplicate these standards and processes. Where such standards and their relationship with radiation safety issues are sufficiently mature, their requirements have been referenced but not reproduced here. This is the case in many aspects of radiotherapy (Sections and 4). Where the relationship is less mature, or there continues to be an overlap between safety standards.
