Radon is a naturally occuring 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 is carrying out a national geographically based radon survey which is scheduled for completion this year. The survey will assist in identifying areas at greatest risk of high indoor radon levels. The institute offers a radon measurement and advisory service to householders. The National Cancer Registry records cancer incidence and mortality in Ireland and cross referencing data with information on relevant risk factors such as radon will contribute to research into the epidemiology of cancer.
The Department of the Environment and Local Government has published guidelines which give information to householders and building designers on measures that may be taken to reduce high radon levels in buildings. The Minister for Public Enterprise is considering the introduction of a radon remediation grant scheme this year to assist householders deal with excessively high levels of radon detected on their premises.
