WHAT IS RADON

Radon is a naturally occurring radioactive gas.  You cannot see, hear, feel or taste it, in fact it requires special devices to monitor it.   It comes from the ground from minute amounts of uranium that occur naturally in all rocks and soils.

WHERE IS RADON FOUND

Radon is present in all parts of the UK, although the gas disperses outdoors so levels are generally very low.  However, concentrations can build up in enclosed spaces, such as houses.

We all breathe it in throughout our lives - for most UK residents, radon accounts for half of their total annual radiation dosage.

However, geological conditions in certain areas can lead to higher than average levels. Some of the highest radon levels have been found in the southwest, but levels well above average have been found in some other parts of the UK, and in particular in parts of Derbyshire. 

WHAT ARE THE RISKS

Exposure to particularly high levels of radon does pose a serious risk to health.  Health studies from around the world have linked radon and lung cancer.  Whilst smoking is the largest cause of lung cancer in this country, radon is the second main cause.   The risks are increased for smokers in radon affected areas.   Radon and smoking work in a synergistic way and so the risk is not just doubled.  It is now believed that smoking just 15 cigarettes a day can multiply the risk by up to 20 times.

The Health Protection Agency has advised that indoor radon above an Action Level of 200 becquerels per cubic metre should be reduced. Most homes in the UK have fairly low radon levels, with an average of about 20 becquerels per cubic metre.  However, if you live in a radon affected area it is wise to have your home tested.  The Health Protection Agency conducts radon surveys for government departments, local councils, other organisations, and private householders.   For more information see the Health Protection Agency website at www.hpa.org.uk or http://www.hpa.org.uk/radiation/radon
