About Cork
Radon Risk in Co. Cork
In EPA measurements to end-2019, 12.7% of homes tested in Cork were at or above the Reference Level of 200 Bq/m³, in line with the national share of 14.1% of homes tested. Because testing was promoted hardest in known high-radon areas, these are shares of homes tested, not of all homes in Cork. Radon is Ireland's leading cause of lung cancer after smoking, making a radon check essential for any property buyer in Cork. PropertyPack includes EPA radon zone data and risk classification for any Eircode in Cork City, Cobh, Mallow and surrounding areas.

Source: Radon results by county, EPA measurements to 31 Dec 2019 (EPA (Environmental Protection Agency)). Homes that tested are a self-selected sample (testing was promoted hardest in high-radon areas), so these percentages overstate county-wide prevalence. Nationally, the EPA's 2022 radon risk map predicts 170,000 Irish homes above the Reference Level, and a High Radon Area is anywhere more than 1 home in 10 is predicted to exceed it.
