Statement

The Indicative Atlas of radon in Great Britain presents a simplified version of the radon potential for Great Britain. It represents a cellular grid coverage of Great Britain with each cell represented by a 1-Km square. Each 1-km grid square being classed according to the highest radon potential found within it (as indicated by the Radon Potential dataset). As a map showing the MAXIMUM potential class for each square, the map is indicative rather than definitive. The radon potential dataset is derived by combining a simplified version of the geology of Great Britain (BGS Geology 50k version 8) with indoor radon measurement data collected by UK Health Security Agency (UKHSA) (formerly 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 Geology 50k (1: 50 000 scale) digital geological map data. A code bedrock/superficial (BS) code is assigned to each of them. Each different simplified geology may appear at the land surface in many discontinuous locations across the country. UK Health Security Agency 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 10.7 software.
