BR 211

Radon Reports and Assessments

Carried out as part of a ground gas assessment and/ or foundation recommendations, radon reports are undertaken in accordance BRE Report BR 211 (2023 edition): "Radon: Guidance on Protective Measures for New Buildings (including supplementary advice for extensions, conversions and refurbishment projects)" .

Depending on a site's location, related to the underlying geology, and the radon risk, full, basic or no radon protective measures are required.

Case Study

Radon Protection General Requirements

Although outside the scope of services usually provided, Ruddlesden geotechnical were able to help with a recent enquiry from a private individual. Whilst the details would need to be designed by a suitably qualified engineer, Ruddlesden were able to confirm the general principles of radon protection in ground floor slab construction, with reference to BRE Report BR211 (2023 edition): Radon: Guidance on Protective Measures for New Buildings (including supplementary advice for extensions, conversions and refurbishment projects). All staff are very familiar with this document as, given the company’s location in southwest England, where elevated levels of naturally occurring radon are commonly present, due the underlying geology, almost all geotechnical and contamination reports include a radon assessment.
