Radon areas in England and Wales

Every building contains radon but the levels are usually low. The chances of a higher level depend on the type of ground. The Health Protection Agency and the British Geological Survey have 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.

The map or a radon risk report for an individual home can only give the likelyhood of a higher radon level.

Radon levels vary between neighbouring homes and with different living styles. To find out the level in your home, you have to measure when you are living there. The measurement is done by post with two small detectors.
