Lambton Public Health is calling on residents to test their homes for radon gas.
According to Health Canada, radon is the second leading cause of lung cancer behind smoking.
Spokesperson Lori Lucas says radon can't be seen, smelled or tasted.
It's a naturally occuring radioactive gas that comes from the breakdown of uranium found in rocks or soil.
"Lambton Public Health can provide information to homeowners on how to test for radon and the options to find a certified radon mitigation contractor," says Lucas.
"Some things to quickly reduce radon include sealing cracks around windows and sump pumps, and any cracks in the foundation."
Lucas says this is the best time of year to test for radon because many people have their windows closed. She says Ontario has an average risk for radon exposure compared to the rest of Canada.
She says the test should be conducted for a minimum of three months in the lowest lived in area of the home.
Test kits are available at local home improvement stores, or online at www.takeactiononradon.ca/test/ontario
