UK maps of radon

This new map confirms the challenge of radon in a number of rural areas, particularly in the South West. Have a look at the map for more information.

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.
