High Radon Levels in Castleisland, Co. Kerry
The Institute conducted a National Radon Survey between 1992 and 1999. Radon measurements were completed in 11,319 homes throughout the country. On the basis of the survey, it is predicted that approximately 91,000 homes will have radon concentrations in excess of the national Reference Level of 200 becquerels per cubic metre (Bq/m3). To date less than 3% of these homes have been identified. The Institute continues to offer a radon measurement service to the public and homes with radon concentrations above the Reference Level are regularly identified.
A radon measurement made in a home close to Castleisland, Co. Kerry between May and July 2003 showed an average radon concentration of 49,000 Bq/m3. This compares with the previously highest measured concentration of 16,500 Bq/m3 recorded in Co. Wicklow in 1999. Since the commencement of the National Radon Survey in 1992, 12 homes have been identified with radon concentrations in the range 2,000 to 6,500 Bq/m3.
