Insight User Guide: Radon

Estimated percentage of dwellings exceeding the Radon Action Level. The highest radon reading within the buffer is provided.

This data is the highest resolution radon dataset available for the UK, produced to a 50m accuracy. This data has been pre-buffered to account for the relative accuracy and other uncertainties, so no additional buffering on site is required. The findings of this section should supersede any estimations derived from the Indicative 1km Atlas of Radon in Great Britain. The data was derived from both geological assessments and long term measurements of radon in more than 560,740 households.
