Winter is the ideal season to screen for the presence of radon in your home. It is then that radon levels are at their highest.
Odourless and colourless, radon seeps up from the ground. Outside, this radioactive gas is harmless, but in enclosed areas, where it can accumulate, it’s another thing entirely. Radon then becomes dangerous: it will be held responsible for 16 percent of the some 7,300 lung cancers to be detected in Quebec this year.
