Radon: Guidance on protective measures for new buildings BR 211
On 6 November 2015, BRE published Radon: Guidance on protective measures for new buildings (BR 211- 2015 edition), written by Chris Scivyer.
|…a naturally occurring radioactive colourless and odourless gas which is formed in small quantities by radioactive decay wherever uranium and radium are found. It can move through the subsoil and so into buildings. Some parts of the country, notably the West Country, have higher levels than elsewhere. Exposure to high levels for long periods increases the risk of developing lung cancer. To reduce this risk all new buildings, extensions and conversions, whether residential or non-domestic, built in areas where there may be elevated radon emissions, may need to incorporate precautions against radon.|
BR 211 provides guidance for reducing the concentration of radon in new buildings, extensions, conversions, and refurbishment projects, and so reducing the risk of occupants being exposed to it. It is intended for use in England, Wales, Scotland and Northern Ireland, and supports building regulations for England, Wales and Northern Ireland, and building standards for Scotland.
It was originally published in 1991 and was subsequently amended in 1992, 1999 and 2007. The 2015 edition replaces previous editions and two earlier guidance documents:
- BRE Report BR 376, Radon: guidance on protective measures for new dwellings in Scotland, introduced in 1999.
- BRE Report BR 413, Radon: guidance on protective measures for new dwellings in Northern Ireland, introduced in 2001.
Its contents are:
- National building regulation guidance.
- Protective measures.
- Determining the level of protection.
- Protective measures: technical approach.
- Detailed protective measures.
- References and further reading.
- Appendix A: Maps of areas where basic or full protection should be provided.
- Appendix B: Radon protective measures quality management checklist.
