The overall aim of this Good Building Guide is to give practical advice and guidance on the successful installation of radon-protective measures in new large buildings (eg workplaces). It should be read in conjunction with BRE Report BR 211, Radon: guidance on protective measures for new buildings. This Good Building Guide replaces the guidance published in 2009. Two companion Good Building Guides cover radon-protective measures for new domestic extensions and conservatories and new dwellings.
