Radon Action Month

November has been established as Radon Action Month in Canada.

Radon is a naturally occurring radioactive gas that you can’t see, smell or taste. Radon is the leading cause of lung cancer after smoking, leading to about 16% of lung cancer deaths each year in Canada. High levels of Radon may be found in any enclosed space such as a home, office building or school. The only way to find out how much Radon is in a building is to test for it.

The best time to test for Radon is during the colder months of the year. November is a great time to start a Radon test to find out if you are at risk – and take action!
