This Good Building Guide gives practical advice and guidance on the successful installation of radon-protective measures in new dwellings. In recent BRE studies an increasing number of new homes built with radon-protective measures are being tested and found to have elevated indoor radon levels. This Guide will help designers, site managers, building control authorities and site operatives to ensure that radon-protection measures work. It should be read in conjunction with BRE Report BR 211 (2007) ‘Radon: guidance on protective measures for new buildings’. Two other Good Building Guides cover radon-protective measures for new extensions and conservatories (GBG 73) and larger buildings (GBG 75).
