The 3rd EANNORM – Workshop was held from 23th to 25th November 2010 in Dresden. It has been organised and hosted by IAF-Radioökologie GmbH and supported by the Federal Office for Radiation Protection Germany. This workshop was dedicated to the topic “Scenarios for Dose Assessments in the NORM industry”. Its main goal was to familiarise the participants with different approaches developed for dose calculations in the NORM industry and to discuss the question on whether a harmonization of these approaches should be pursued or not. 45 experts coming from 14 countries took part in the discussions and shared their experiences.

All talks had a length of 45 minutes including ample time for discussion. Each daily session was finished after a special round table discussion of about 1 hour on “burning questions”. The talks reflected a wide range of situations in which the presence of NORM can cause a radiation exposures to workers and/or to members of the public at a level which cannot be ignored from the radiation protection point of view. The presentations of the EANNORM Round Table Workshop on “Scenarios for Dose Assessments in the NORM industry” are available below.
