Radon

Radon is a naturally occurring gas, which results from the radioactive decay of uranium. It is found in small quantities in all rocks and soil. The gas disperses quickly in the open air, but can accumulate in buildings, especially in areas where the underlying ground contains higher than average traces of uranium and is permeable.

A number of factors determine whether radon accumulates in a building - for example the way it is constructed or used. Levels may vary between adjacent homes. A radon-affected area is where one per cent of the homes are likely to have radon concentrations above the Government action level of 200 bequerels per cubic metre of air.

Radon is a cause of concern as exposure to the gas over time increases the risk of lung cancer, particularly among smokers. The Health Protection Agency estimate that five per cent of lung cancer deaths in Great Britain may be attributable to radon.

New homes are protected through the building regulation requirements in high radon areas. Measures to reduce the levels in existing homes may be installed at modest cost. To help you decide whether to install such measures the Health Protection Agency provides a radon measurement service. For more information visit their website.
