BGS/UKHSA Radon data: Indicative Atlas of Radon | Open Data Downloads | Data | OS Data Hub

The joint UK Health Security Agency (UKHSA)-BGS Indicative Atlas of Radon in the United Kingdom presents an overview of the results of detailed mapping of radon potential (defined as the estimated percentage of homes in an area above the radon action level).

The Radon potential dataset for the United Kingdom provides the current definitive map of radon-affected areas in the United Kingdom. This data presents a simplified version of the radon potential dataset with each 1 km-grid square being classed according to the highest radon potential found within it, so is indicative rather than definitive.

UKHSA recommends that radon levels should be reduced in homes where the annual average is at or above 200 becquerels per cubic metre (200 Bq/m³ ) — this is termed the radon action level.

Further investigation can be carried out using the detailed BGS/UKHSA Radon Potential dataset.
