Radon in indoor air is the second biggest cause of lung cancer (WHO 1998, Darby et al., 2005). Radon gas diffuses through soil into residences in areas where bedrock contains in excess uranium. Radon evaporates also from household water into air upon warming. High radon concentrations have been measured indoors locally in several countries.

Testing is the only way to know if you and your family are at risk from radon. Testing is inexpensive and easy it should only take a few minutes of your time. Millions of home in the UK have already tested their homes for radon

The test result is expressed in units that are directly comparable with the government Action Level. The Health Protection Agency recommends that radon levels should be reduced in indoor space where the average is more than 200 becquerels per cubic metre. This recommendation has been endorsed by the Government.

9% of lung cancer deaths are attributable to radon gas
