Residents across the north west are being urged to check levels of Radon in their homes.
Radon is a radioactive gas that causes lung cancer that is formed in the ground by the radioactive decay of uranium which is present in all rocks and soils.
According to information from the Environmental Protection Agency’s website, there are high levels of Radon in many parts of Sligo, more so in the west.
The EPA map shows areas in the county where it estimated that more than 20% of homes in a given 10km radius have levels above their reference level.
Speaking to OceanFM news, Sligo Councillor Dara Mulvey says that fortunately, measures can be put in place to reduce the amount of gas present.
