Where is radon found?

Radon levels are low everywhere outdoors. In most cases the level of radon indoors is low and the risk to health is small.  However, indoor level of radon depends on the ground below and how the building is used.

You can check if you are in a radon affected area or ‘hotspot’  by using an indicative map, produced by Public Health England and British Geological Survey,  available from UKRadon.

The darker the colour, the greater the chance of a higher radon level indoors. If you live or work in or near a radon ‘hotspot’ we advise that you measure the levels indoors.
