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.

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