This report presents an overview of the results of detailed mapping in England and Wales of radon potential, defined as the estimated percentage of homes in an area above the radon action Level. 皇冠体育app work was carried out jointly by the Health Protection Agency (now Public Health England) and the British Geological Survey, and was based on the results of measurements of radon in 460,000 homes.

皇冠体育app method allows variations in radon potential both between and within geological units to be mapped. 皇冠体育app resulting map, which defines radon affected areas in England and Wales, includes much more detail than could be shown in an atlas. 皇冠体育app full detail is instead published as a dataset which can be licensed for use in geographical information systems. 皇冠体育app estimated radon potential for an individual home can be obtained from .

皇冠体育app 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.
