The overarching theme for ICRP 2021+1 is Radiological Protection – The Next Generation, and the presentations, posters, and exhibitions will reflect just that. Over the next decade, ICRP will concentrate its efforts on reviewing the System of Radiological Protection to produce the next set of fundamental recommendations that will guide legislation, practice, and policy around the globe. During this process, ICRP will be engaging with many professionals and organisations, and will require unprecedented resources to ensure the System of Radiological Protection is fit for purpose for many years to come. Following the success of our Digital Workshop on The Future of Radiological Protection (October 2021), ICRP 2021+1 will provide the opportunity for delegates, organisations, and ICRP membership to continue the discussion, relationships, and planning that will guide this important work for the next 10+ years.
