Test your home for radon
Radon gas identified as second leading cause of lung cancer, after smoking. Health Canada encourages you to test your home for radon during Lung Cancer Awareness Month.
Radon is a naturally occurring radioactive gas in the ground that can't be seen, smelled or tasted. It can get into the home undetected through cracks in the foundation or gaps around pipes. The only way to measure the radon level in the home is to take a simple and inexpensive test, which can be purchased at most hardware stores. Health Canada recommends testing for a minimum of three months starting in the fall, when windows and doors typically remain closed.
