Myths vs. Facts
Myth: Granite work tops emit harmful levels of radon.

The New York Times has reported that spurious claims about radon levels in granite work tops have been made by companies selling competitive worktop materials.
Myth: Radon is only a problem in granite areas.
Fact: High radon levels are found on many different rock types around the country, including some limestones and sandstones.
Myth: Houses with high radon levels are blighted.
Fact: High radon level houses can be remedied and there is no evidence that radon has caused any housing blight.
Myth: Radon causes leukaemia or other cancers.

Myth: Radon level are high in Devon and Cornwall, but the lung cancer rate is low, so radon cannot cause lung cancer.
Fact: Most lung cancers are caused by smoking. Studies have shown smoking rates are low in Cornwall, giving a low rate of lung cancer. However, studies of people in Cornwall and Devon have shown that higher radon levels in houses are associated with a higher risk of lung cancer for people living in those houses.
