Challenges in harmonising controls on the radioactivity of building materials within the European Union

Possibilities for harmonising controls on the radioactivity of building materials within the European Union are being discussed in a Working Party on Natural Radiation Sources established by the Article 31 Group of Experts ŽEuratom Treaty.. The Working Party is preparing a document to aid the Article 31 Expert Group and the European Commission in considering possible recommendations and technical guidance to the Member States for the implementation of the new Basic Safety Standards Directive concerning the radioactivity of building materials. The discussions in the working party have demonstrated several challenges in the possible harmonisation of controls, many of them arising from some significant differences in national circumstances.
