In 2005, the International Commission on Radiological Protection (ICRP) decided to create a new committee, Committee 5, to take charge of the Commission’s work on environmental radiological protection. Committee 5 was tasked with ensuring that the system for environmental radiological protection would be reconcilable with that for radiological protection of humans, and with the approaches used for protection of the environment from other potential hazards. The task was completed over three consecutive terms, resulting in inclusion of protection of the environment in the 2007 Recommendations; in ICRP Publications 108 and 114 where the concept of Reference Animals and Plants (RAPs) and their corresponding data were described; in ICRP Publication 124 on how to apply the system in planned, existing, and emergency exposure situations; and in publications on improved dosimetry (ICRP Publication 136) and ecologically relevant ‘weighting factors’ for different types of radiation (being finalised for public consultation). With the beginning of this new term, ICRP has moved to integrate its approach to protection of humans and the environment within the system of radiological protection by tasking aspects of an integrated system to each of the committees. Acknowledging that Committee 5 had fulfilled its mission, in 2016, ICRP revised the mandates for the committees effective of 1 July 2017 (the mandate for Committee 3 was also widened to include exposures incurred in veterinary practice). ICRP is moving towards the future, building on the previous successes, and will under these revised mandates approach radiological protection in a holistic manner (an integrated system) where appropriate consideration is given to the understanding of exposures and effects in the environment under different exposure situations and scenarios, and what protective actions might be warranted under such circumstances.
