Radon Potential for Great Britain version 3
Radon is a natural radioactive gas, which enters buildings from the ground. The joint UK Health Security Agency (UKHSA) - British Geological Survey (BGS) Radon Potential for Great Britain digital dataset provides the current definitive map of Radon Affected Areas in Great Britain. Exposure to high concentrations of radon increases the risk of lung cancer. The UK Health Security Agency (formerly Public Health England, PHE) recommends that radon levels should be reduced in homes where the annual a
