Radon: indicative atlas in Scotland

This report (HPA-CRCE-023) is a radon atlas showing the bands of radon risk in each 1 kilometre grid square of Scotland.



This report supersedes ‘Radon in Dwellings in Scotland: 2008 Review and Atlas’ (HPA-RPD-051).

This report presents an overview of the results of detailed mapping of radon potential in Scotland, defined as the estimated percentage of homes in an area at or above the radon action level.

The 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 over 19,000 homes. The method allows variations in radon potential both between and within geological units to be mapped. The resulting digital map, which defines radon affected areas in Scotland, includes much more detail than could be shown in an atlas.

The full detail is published as a dataset for Geographical Information Systems (GIS), which can be licensed. The estimated radon potential for an individual home can be obtained from UKradon. The atlas presented here is 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.
