How does radon cause lung cancer?
Radon is a radioactive gas. When we breathe it in, we are exposing our lung tissue to ionizing radiation. This radiation causes damage to the DNA in our lung tissue and can lead to lung cancer.

Radon is a health concern that Canadian homeowners need to take seriously. Just as deaths from carbon monoxide, house fires, and car accidents can be reduced, so can deaths from radon exposure be reduced. All homeowners need to test their home to know if they are at risk, and reduce their radon levels if they are too high.
