Radon Risk in Co. Sligo, Connacht
In EPA measurements to end-2019, 24.9% of homes tested in Sligo were at or above the Reference Level of 200 Bq/m³ — above 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 Sligo. Radon is Ireland's leading cause of lung cancer after smoking, making a radon check essential for any property buyer in Sligo. PropertyPack includes EPA radon zone data and risk classification for any Eircode in Sligo, Tubbercurry, Enniscrone 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.

In EPA measurements to end-2019, 24.9% of homes tested in Sligo were at or above the Reference Level of 200 Bq/m³ — above the national share of 14.1% of homes tested. Homes in known high-radon areas were more likely to test, so this is a share of homes tested, not of all homes. Radon is Ireland's second biggest cause of lung cancer, and the EPA recommends testing any home regardless of area.
PropertyPack includes EPA radon zone classification for any Eircode in Sligo. For definitive measurement, a physical radon test using detectors placed in the property for 3+ months is recommended. PropertyPack data tells you whether your area is classified as high-risk before you invest in testing.
Risk levels vary across Sligo depending on which factor you're considering. Properties away from Garavogue, Ballisodare and Moy flood plains have lower flood risk. For radon, 24.9% of homes tested in Sligo measured over the Reference Level — the EPA's map shows which areas are classified as High Radon Areas.
