Radon is a natural radioactive gas, which enters buildings from the ground. Exposure to high concentrations increases the risk of lung cancer. Public Health England (PHE) recommends that radon levels should be reduced in homes where the annual average exceed 200 becquerels per cubic metre (200 Bq m-3), the radon Action Level. PHE defines radon Affected Areas as those with 1% chance or more of a house having a radon concentration exceeding the Action Level.
The joint PHE-GSNI-BGS digital INDICATIVE ATLAS OF RADON IN NORTHERN IRELAND, in the SHP and LYR Radon_Atlas_NI_V1 files, 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 INDICATIVE ATLAS OF RADON IN NORTHERN IRELAND presents a simplified version of the RADON POTENTIAL DATASET FOR NORTHERN IRELAND, with each 1-km grid square being classed according to the highest radon potential found within it, so is indicative rather than definitive. The RADON POTENTIAL DATASET FOR NORTHERN IRELAND provides the current definitive map of radon Affected Areas in Northern Ireland.
The INDICATIVE ATLAS OF RADON IN NORTHERN IRELAND is published in Z DARAKTCHIEVA, J D APPLETON, D M REES, K A M ADLAM, A H MYERS, S A HODGSON, N P McCOLL, G R WASSON and L J PEAKE, 2015. Indicative Atlas of Radon in Northern Ireland. PHE-CRCE-017, 22 pp

The method by which the PHE-GSNI-BGS joint INDICATIVE ATLAS OF RADON IN NORTHERN IRELAND was produced is published in: MILES, J.C.H, and APPLETON J.D., 2005. Mapping variation in radon potential both between and within geological units. Journal of Radiological Protection 25, 257-276.

Derivation of radon potential data for Northern Ireland was carried out by the BGS, working in collaboration with the GSNI and the PHE. Finalisation of the data set by BGS was carried out using funding from the BGS Derived Products programme of the Information Products science area and Geochemical Hazards under Hazard Products programme of the Environmental Modelling science area.
