Questions people ask
- Is Co. Cork a high radon county?
- 116 of the 141 town centres we sampled in Co. Cork are in an EPA High Radon Area (1 in 5 homes or more predicted above 200 Bq/m³). Nationally it is 36% of towns. High towns include Midleton, Carrigaline, Douglas, Cobh, Ballincollig, Cork.
- What does a High Radon Area mean for a buyer?
- Houses built after 1998 in a High Radon Area must have a radon barrier. Older houses usually have none, and one in five will test above the reference level. It costs €50 to €60 to test after you move in and €1,500 to €3,000 to fix. Ask the seller for any test result.
- Why does radon vary so much within a county?
- Radon comes from uranium in the underlying rock. Granite and some limestones give high readings; the map follows the geology, so it changes over a few kilometres. The exact Eircode grid square is what matters.
