Question:154 Mr. F. McGrath asked the Minister for Health and Children the position regarding the effects of radon gas on the population and its connection with cancer deaths. [31841/03]
Written Answers. - Radon Gas Levels.
The International Agency for Research on Cancer operates under the aegis of the World Health Organisation. It classified radon, a naturally occurring radioactive gas, as a class A carcinogen. Radon has been shown to cause cancer, specifically lung cancer, on the basis of human epidemiological studies. Prolonged exposure to elevated levels of radon gas in an enclosed area can be a contributory factor in increasing the risk of lung cancer, particularly where other factors such as cigarette smoking are involved. My Department has been advised by the Radiological Protection Institute of Ireland that while smoking is the primary cause of lung cancer worldwide, it is estimated that 10% of lung cancer deaths in Ireland each year may be associated with radon exposure, many of which will be among smokers rather than non-smokers.
The monitoring of radiation levels in the State is carried out by the RPII, which operates under the aegis of the Department of the Environment, Heritage and Local Government. The institute identified areas at greatest risk from high indoor radon levels. Householders living in these areas are urged to measure radon levels in their homes and to take remedial action if high levels are found. The RPII also provides a radon measurement and advisory service.
Radon in the workplace is subject to health and safety legislation. Employers in high radon areas are required to carry out radon measurements and take remedial action if necessary. My colleague, the Minister for the Environment, Heritage and Local Government is responsible for building regulations that incorporate radon preventive measures in new dwellings.
