Abstract:
Radon is a natural radioactive gas, which enters buildings from the ground. The joint Public Health England (PHE) –British Geological Survey (BGS) digital dataset Radon Potential for Great Britain provides the current definitive map of radon Affected Areas in Great Britain. Exposure to high concentrations increases the risk of lung cancer. PHE (previously known as the Health Protection Agency or HPA) 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. The PHE 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 allows an estimate to be made of the probability that an individual property is at or above the Action Level for radon. 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. Radon Potential 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, 2015 in Scotland, England, Wales and Northern Ireland). This radon potential hazard information for Great Britain is based on PHE indoor radon measurements and BGS digital geology information. This product was derived from BGS Geology 50 (formerly known as 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 under licence.

statement:
The Radon Potential GB dataset is derived by combining a simplified version of the geology of Great Britain (BGS DiGMapGB 50 version 3.14 now known as BGS Geology 50) with indoor radon measurement data collected by the Health Protection Agency (now known as Public Health England (PHE)). The land area is first divided up into simplified geologies, a combination of bedrock and superficial geological characteristics, derived from BGS DiGMapGB 50 (1: 50 000 scale) digital geological map. A code bedrock/superficial (BS) code is assigned to each combined geology. Each different simplified geology may appear at the land surface in many discontinuous locations across the country. Each simplified geology is then divided in 1 Km squares by using the OS British National Grid. From this division results a list of spatially referenced KMBS (a simplification of 1 Km2 / BS) polygons containing information about both the simplified geology and the BNG 1km square. Public Health England has a database of houses in which long-term (3 to 6 months) measurements of radon concentration have been made, and whose locations are accurately known. Each of these measurements is allocated to the underlying geological polygon followed by actual measurements' coordinates stripping off. This procedure allows for anonymization of house data. Taking each simplified geology in turn, the spatial variation of radon potential is mapped, treating the geology as if it were continuous over the land area. Bedrock, stratigraphic (order in which rock layers are laid down) or lithological (rock characteristics) generalisations of the simplified geologies may be required to assure that the number of radon measurements is enough to estimation the radon potential. All of the maps of radon potential within different simplified geologies are then combined to produce a map of variation in radon potential over the whole land surface. This dataset formed the raw data on which processing was carried out to ensure all end-users would achieve consistent results. All data processing was carried out using ESRI ArcGIS 9.3.1 software.
