Radon
Layer name: Radon-Radon_UKHSA_BGS
This is a polygon based dataset that provides details on the estimated percentage of dwellings exceeding the Radon Action Level (200 becquerels) across England, Wales and Scotland. This data is the highest resolution radon dataset available and is produced to a 75m level of accuracy to allow for geological data accuracy and a 'residential property' buffer. The data was derived from both geological assessments and long term measurements of radon in more than 479,000 households and was a joint project between the BGS and PHE (formerly the Health Protection Agency).
