Radon is a naturally occurring radioactive gas, found in small amounts in all rock and soil. Radon seeps out of the ground and can collect in enclosed spaces such as buildings through floors.

Most buildings have low levels of radon that are not a problem. If levels are high they can usually be reduced for a reasonable cost.

Health risks from radon

Exposure to long term high levels of radon is associated with an increased risk of developing lung cancer, particularly if combined with smoking.

The Health Protection Agency advice is that homes with radon levels:

  • above the Action Level of 200 becquerels per cubic metre (Bq/m3) should be reduced, preferably to below the Target Level of 100 Bq/m3
  • between the Target Level and Action Level should seriously consider reducing their radon level, especially if they are at greater risk, such as if they are or have been smokers

Radon in West Oxfordshire

Much of the northern area of West Oxfordshire is affected by radon. There is a radon programme to identify homes with unacceptably high levels so they can be reduced. Since 1999 new homes being built are protected through building regulation requirements.

We cannot provide information on radon levels in individual properties or specific areas. For up to date data and enquiries please contact UK Radon.

Testing for radon

Most buildings have low levels of radon that aren't a problem.
