Radon gas

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.

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.

The leaflet “Radon in your Home - Don’t live with the Risk” has been produced by Isle of Anglesey County Council. This leaflet includes a map of radon affected areas on Anglesey which can be viewed as an attachment below.
