What is Radon?

Radon is a naturally occurring radioactive gas formed by the breakdown of uranium in soil, rock, and groundwater. It is colorless, odorless, and tasteless, making it undetectable without specialized testing. Health Canada reports that it is the #1 cause of lung cancer in non-smokers. With increased public awareness of these risks in the built environment, the 2024 Ontario Building Code (OBC) has been updated to improve health and safety measures relating to radon.
