The NKS-B RadWorkshop 2018 (Workshop on Radioanalytical Chemistry for Nuclear Decommissioning and Waste Management) was held at Risø, Denmark, during 8-12 October 2018. The workshop consisted of 3-day invited lectures and presentations from participants and 2-day lab practice by very experienced professionals. A number of highly reputed experts from authorities, research institutes and nuclear industries were invited to give state-of-the art lectures in different aspects in nuclear decommissioning and waste management with the focus on radioanalytical chemistry. The lab training demonstrated the radiochemical analysis of alpha emitters (Pu-239, 240 and Am-241) and beta emitters (Fe-55, Ni-63) in nuclear decommissioning materials. 90 participants from 41 international organisations attended the workshop.
