Limerick East): Radon is a naturally occurring radioactive gas. Long-term exposure to very high levels of radon in an enclosed area can be a contributory factor in increasing the risk of contracting lung cancer, particularly where other factors such as cigarette smoking are involved.
The Radiological Protection Institute of Ireland is the statutory body with responsibility for monitoring radiation in the State. The institute initiated a national geographically based radon survey in 1992 which will extend over a number of years. The target date for completion is 1998. The survey is being carried out to assist in identifying areas at greatest risk of high indoor radon levels. I should also mention that the Radiological Protection Institute provides a radon measurement and advisory service to the public.
