Draft Abstract: The International Commission on Radiological Protection (ICRP) first introduced the term ‘diagnostic reference level’ (DRL) in Publication 73 (1996). The concept was subsequently developed further, and practical guidance was provided in 2001. DRLs have been proven to be an effective tool that aids in optimisation of protection in the medical exposure of patients for diagnostic and interventional procedures. However, with time it has become evident that additional advice is needed. There are issues related to definitions of the terms used in previous guidance, determination of the values for DRLs, the appropriate interval for re-evaluating and updating these values, appropriate use of DRLs in clinical practice, methods for practical application of this tool, and application of the DRL concept to newer imaging technologies. This report is intended as a further source of information and guidance on these issues. Some terminology has been clarified. In addition, the report recommends quantities for use as DRLs for various imaging modalities, and provides information on use of DRLs for interventional procedures and in paediatric imaging. It suggests modifications in the conduct of DRL surveys that take advantage of automated reporting of radiation dose related quantities, and points out the importance of including information on DRLs in training programmes for health care workers. The target audience for this report is national, regional and local authorities, professional societies, facilities where ionising radiation is used for medical purposes, and responsible staff within these facilities. A full set of the Commission’s recommendations is provided.
