Public Health England (PHE) - British Geological Survey (BGS) Joint Radon Potential Dataset for Great Britain

Dataset description

The joint PHE-BGS digital Radon Potential Dataset for Great Britain provides the current definitive map of radon Affected Areas in Great Britain. It will also allow an estimate to be made of the probability that an individual property is at or above the Action Level for radon. In England and Wales this information provides an answer to one of the standard legal enquiries on house purchase in England and Wales, known as CON29 standard Enquiry of Local Authority; 3.13 Radon Gas: Location of the Property in a Radon Affected Area. The Radon Potential Dataset for Great Britain also provides information on the level of protection required for new buildings as described in the latest Building Research Establishment guidance on radon protective measures for new buildings (Radon: guidance on protective measures for new dwellings; BR 211, 2007 in England and Wales; BR376, 1999 in Scotland). This radon potential hazard information for Great Britain is based on Public Health England (PHE) indoor radon measurements and BGS digital geology information. This product was derived from DigMap50 V3.14 and PHE in-house radon measurement data. The indoor radon data is used with the agreement of the PHE. Confidentiality of measurement locations is maintained through data management practices. Access to the data is restricted. Radon is a natural radioactive gas, which enters buildings from the ground. Exposure to high concentrations increases the risk of lung cancer. Public Health England recommends that radon levels should be reduced in homes where the annual average is at or above 200 becquerels per cubic metre (200 Bq m-3). This is termed the Action Level. Public Health England defines radon Affected Areas as those with 1% chance or more of a house having a radon concentration at or above the Action Level of 200 Bq m-3. The dataset was originally developed by BGS with the Health Protection Agency (HPA) which is now part of Public Health England.

Constraints

Access currently restricted to BGS data managers, system developers and BGS Enquiry staff delivering radon assessments to external clients. Restricted due to confidentiality undertakings with the PHE.
