Action urged after radon gas tests in Oxfordshire
Residents in hundreds of homes across West Oxfordshire are being urged to reduce their exposure to radon gas.
The Health Protection Agency (HPA) assessed about 4,000 households for radon gas and found 14% needed to take action to reduce the level.
Radon is a natural radioactive gas which is believed to be linked to lung cancer.
The agency is now holding sessions to advise how to reduce radon in homes.
Neil McColl, from the HPA, said: "Whenever we run testing programmes we find a small number of properties with unusually high readings.
"If your home is shown to have high levels of radon, you can then take practical steps to reduce your exposure and minimise your risk."
Anyone wanting more information can attend a number of drop-in events in West Oxfordshire.
Staff will be at Langdale Hall, Market Square, Witney, on 6 February between 14:00 - 20:00 GMT, The War Memorial Hall, Browns Lane, Charlbury, on 7 February between 10:00 - 20:00 GMT and The Town Hall, Market Place, Chipping Norton, on 8 and 9 February, 10:00 - 20:00 GMT.
