the goal of RENEB is to establish a sustainable European network in biological dosimetry involving 23 organisations from 16 countries identified by the TENEB survey, that will guarantee highest efficiency in processing and scoring of biological samples for fast and reliable results implemented in the EU emergency management in case of a large-scale radiological accident. A well organised cooperated action involving EU laboratories will offer the only chance for a fast and reliable dose assessment urgently needed in such an emergency situation.
