Radon
Radon is a naturally occurring radioactive gas formed as a result of the radioactive decay of uranium, which is present in all rocks and soils.
It rises from the soil into the air, outdoors, radon is diluted into the air and the risk it poses is negligible.
Where it enters buildings, the levels of radon can build up and, at high concentrations, leads to an increased risk of lung cancer.
Radioactivity is measured in Becquerels. The Government has established an Action Level for radon in homes of 200 Becquerels per cubic metre (Bq/m3), based on advice from the Health Protection Agency (HPA).
The Radon in Dwellings Report produced in 1999 by the Environment and Heritage Service (EHS) (On 1 July 2008 EHS became Northern Ireland Environment Agency) includes a radon map of Northern Ireland (from Health protection Agency website)
and the risk and information on radon tests carried out in the Province. The average level is low at 19 Bq/m3, similar to the rest of the United Kingdom. The radon map shows that there are areas in the West of the province and the southeast where radon risk is elevated. It is estimated that 4000 homes in Northern Ireland are likely to exceed the action level. Free booklets can be obtained from us at the address below;
