What is radon?
Radon is a natural radioactive gas, which decays into other radioactive species, all of which cause human exposure to radiation.
What are the effects of radon?
Miners exposed to high radon levels have been found to run an increased risk of lung cancer. Radon in the home also presents a risk, but generally at a lower level.
Is only the South-West of England affected by radon?
No. Radon is present in all parts of the UK, but in the most populous areas the levels are quite low. Some of the highest levels have been found in the south-west, but levels well above average have been found in some other parts of England and parts of Scotland, Wales and Northern Ireland. However, even in these areas most homes have low levels.
I am extending my house. Is there anything I can do to prevent radon entering into the extension?
Yes. Using the advice for new buildings will help to avoid the problem. Particular attention should be paid to the join between the old and new parts. Contact the building control officer for your area for further advice.
How do I discover if my new home has a high level of radon?
Even in Affected Areas most homes have low levels of radon, and high levels can generally be reduced at fairly moderate cost. Concern about radon should not therefore influence your choice of home. Further advice is given in the booklet Radon: A guide for homebuyers and sellers published by the Government. Once you have moved, you can obtain a measurement for a small fee. The test is confidential, the significance of the result is explained and advice is provided on how to reduce high levels.
Do radon levels vary with time?
Yes. Radon levels in homes vary during the day, from one day to the next, and from winter to summer, mainly because of temperature differences between indoors and outdoors. They are generally higher at night and during the winter.
Is there any danger from growing fruit and vegetables in areas affected by radon?
No. Exposure from the natural radioactivity in food is much less than from radon in the home.
