In the framework of the approved HERCA Action Plan in relation to the transposition and implementation of the new Euratom BSS (Stockholm, 22 October 2015) a second European Workshop on National Radon Action plans was organised by FOPH (Switzerland), NRPA (Norway) and ASN (France) on behalf of HERCA in Geneva on 12-14 October 2015.

The main objective of the first workshop was to share the views and experiences concerning national strategies for reducing radon exposure of the population and associated lung cancer risk.

The main objective of this 2nd European workshop was to provide a forum for European countries to exchange points of view on the transposition of the specific requirements of the BSS dealing with radon exposure in workplaces (articles 5, 9, 23, 25, 31, 35, 54, 103, annex XVIII (2, 3, 4, 5, 6, 10)) and the impact on the existing national approach and strategy.

The workshop was targeted primarily on regulators from European countries represented in HERCA or invited by HERCA members. The European Commission as well as relevant international organizations such as WHO, IAEA, ILO and ICRP participated.

The final report of the 2nd radon workshop is now available. Some recommendations underline, in particular, the need for international tools for the radon dose calculation and for European guidelines to facilitate the implementation of the new BSS requirements.
