The radon potential dataset is designed to tell users whether a property is in a radon affected area and if so, what level of protective measures are required. This dataset will be updated to use new data from Public Health England (PHE) and the most up to date version of DiGMap50 data.

Potentially harmful element datasets will be updated using the most up to date version of DiGMap50 data.

We use normal background concentration values from the Geochemical Baseline Survey of the Environment (G-BASE) data to create new datasets for a broad range of uses.
