The Environmental Protection Agency has issued an appeal to householders living in high level radon areas to get their homes checked.
Over 4,700 homes across Ireland were tested for radon and 733 of these had raised radon levels, almost 80 had extremely high radon levels.
The highest home tested in Ireland was found to have over 24 times the acceptable level; this level can deliver a radiation dose equivalent to 17 chest X-rays every day.
In Donegal extremely high levels of Radon were recorded in Muff, recording an estimated percentage over 20% of homes in the area are above the reference levels of radon.
Ballyshannon, Castlefin, Greencastle, Manorcunningham and Rossnowlag all fell within the percentage of an area of high radon levels.
Kilmacrennan and Milford had the lowest levels of Radon with Letterkenny recording between 1-5% of estimated homes above the reference level of Radon.
David Fenton, Senior Scientist with the EPA’s Office of Radiological Protection that every two days someone dies from a radon induced lung cancer in Ireland – since 2010 some 1,700 people have died from this preventable health problem.
