Radon Gas

Radon is a naturally-occurring radioactive gas which enters buildings from the ground and gives radiation doses to the occupants. The first time that most people become aware of radon is when they come to sell their property and the question is raised as part of the conveyancing process.

The Health Protection Agency (HPA) and the British Geological Survey (BGS) have jointly launched a new radon dataset for England and Wales. This dataset supersedes The Radon Atlas of England and Wales (W26) 2002.

The new dataset provides a radon-probability banding for each individual property with a valid postal address instead of a value for the whole 5 km or 1 km grid square as in W26.

A simplified version of the new dataset is available for download by clicking on the link below.

Indicative Atlas of Radon in England and Wales (HPA-RPD-033)  (2.74 MB)

A summary of what radon is and its effects is available in this short questions and answers document.  (5.98 KB)

In addition, for a fee of £3.53, a search can be carried out on the new UK radon web site, www.ukradon.org
