PHE has published reports containing radon Affected Area maps for the whole of the United Kingdom. Copies of the reports are available to download using the links at the bottom of this page.

Every building contains radon but the levels are usually low. The chances of a higher level depend on the type of ground. Public Health England has published a map showing where high levels are more likely.

The darker the colour the greater the chance of a higher level. The chance is less than one home in a hundred in the white areas and greater than one in three in the darkest areas.
