This workshop is organized by the French Institute for Radiological protection and Nuclear Safety (IRSN) under the aegis of the International Union of Radioecology (IUR) and with the support of the Norwegian Radiation Protection Authority (NRPA). It will be hosted as a related event of the next ICRER 2014 Conference and is open to all participants of the ICRER conference.
