BRE GG75 PDF

This Good Building Guide gives practical advice and guidance on the successful installation of radon-protective measures within large buildings, eg laying a radon-proof barrier across a large floor area, how many sumps to install and how to construct the sump and pipework. In addition to the requirements of building regulations, a building used as a workplace has to meet the requirements of the Ionising Radiations Regulations 1999. This Good Building Guide should be read in conjunction with the guidance given in BRE Report BR 211 (2007) Radon: guidance on protective measures for new buildings. Two companion Good Building Guides cover radon-protective measures for new extensions and conservatories (GBG 73) and new dwellings (GBG 74).
