In Europe the Directive for protection against the dangers arising from ionising radiation (COUNCIL DIRECTIVE 2013/59/EURATOM OF 5 DECEMBER 2013), obliges the member states to ensure that appropiate measures are in place to prevent radon ingress into new buildings. The statutory reference value in workplaces and dwellings is 300 Bq/m³. Many of our Hauff products have already been tested for radon tightness.
