This report presents an overview of the results of detailed mapping in England and Wales of radonpotential, defined as the estimated percentage of homes in an area above the radon Action Level. The work was carried out jointly by the Health Protection Agency and the British Geological Survey and was based on the results of measurements of radon in 460,000 homes. The method allows variations in radon potential both between and within geological units to be mapped. The resulting map, which defines radon affected areas in England and Wales, includes much more detail than could be shown in an atlas. The full detail is instead published as a dataset which can be licensed for use in geographical information systems. The estimated radon potential for an individual home can be obtained through a website, www.UKradon.org [outside link]. The atlas presents a simplified version of the map, so is indicative rather than definitive: that is, each 1-km grid square is coloured according to the highest radon potential found within it.
Users should note that the quality of the maps has been downgraded to permit ease of download. The hard-copy radon atlas is printed in full colour and to a higher resolution.
The copyright of this report is held jointly by the Health Protection Agency and the British Geological Survey.
