Radon in the Environment

Radon is a naturally occuring radioactive gas found in soil and rocks, which can accumulate in houses. High concentrations of radon are of concern because worldwide studies have linked it with lung cancer. People exposed to high levels are more prone to lung cancer and smokers are at greater risk.  For more information on radon and radon testing go to UKradon

Radon Levels in Charnwood

  • The HPA have produced an 'Indicative' Radon map of the UK which gives a percentage number of homes within each 1km square estimated to be above the Action Level
  • Of the results known to Charnwood Borough Council up until 2004 there has been 1 result above the Action Level. Since 2004 we do not get given individual results from within the borough.
  • The average radon concentration found up until 2004 was 30 Bq/m3.
  • Most of the Borough of Charnwood lies in an area at lowest risk from radon.
  • There are a few areas in the north-west, west and south-west of the Borough and a small area covering Mountsorrel and the south of Quorn which are thought to have a small number of properties with radon gas levels above the Action level.
  • In these areas it is recommended that houses are tested for radon levels. Alternatively occupiers can apply for a risk report to be produced. This will give a more accurate idea as to whether the property could be at high risk from radon. Please refer to Radon Risk Reports and Testing for Radon below.

Radon Risk Reports

A service provided by the British Geological Association allows a web-based risk assessment to be derived for any property, provided that its postcode and postal address is known. There is a small charge for this. A link to the relevant web site is included below.

Testing for Radon

The HPA has devised a safe, simple and confidential test to measure levels in the home. Two detectors are sent by post. The test equipment is easy to set up one in a living room, the other in a bedroom. These are returned to the HPA after 3 months in a pre-paid envelope.
