Homeowners in Windsor and Essex County are encouraged to apply for a free radon test kit to measure the radon level in their homes. The Health Unit will distribute 1000 radon test kits to area homeowners who qualify.

The Canadian guideline for radon levels in a home is 200 Becquerel’s per cubic metre (Bq/m3). Results from last year’s study data show that 15% of homes in Windsor-Essex have radon levels above the guideline. “Our goal for this year’s study is to continue to raise awareness of the risks of radon gas, and encourage all homeowners to test their homes to find out their levels” says Karen Lukic, Health Promotion Specialist for the Windsor-Essex County Health Unit. “Many people are not aware that radon gas is in almost every home, and that levels can be high in one house, while the one next door is safe.

Homeowners in Windsor and Essex County who are interested in being a part of the ‘Radon: Know Your Level Study’, and getting a free radon test kit, will be required to complete a survey application. Survey applications are available online or in person at all WECHU office locations. Visit or call the Health Unit 519-258-2146 ext. 1454 for more information.

The only way to know the radon level in YOUR HOME is to test for it!


Radon is produced when uranium, found in soil, rock or water decays. Radon is found across Canada because it occurs naturally in soil. The gas rises up from the soil and can get into any type of building, where it builds up due to negative pressure and lack of air flow.

Radon gas can get into your home wherever there is an opening: cracks, gaps, spaces around pipes, through floor drains, sump pumps, etc. Radon levels are often the highest in basements and crawl spaces because they are the closest to the ground and often have poor ventilation. It is important to know that radon levels are not the same in every home. Your radon level may be very different than your neighbours.

If the radon level in your home is above the Canadian guideline of 200 Bq/m3, you should take action to reduce it to a level as low as possible. However, it is important to note that there is no level of radon exposure that is considered risk-free. It is the choice of the homeowner to decide what level of radon exposure they are willing to accept and to act accordingly. The higher the radon level, the sooner your home should be fixed.

Breathing in radon gas for extended periods of time can potentially be hazardous to you and your family and is the second leading cause of lung cancer, after smoking.

November is Radon Action Month. For more information on radon, visit the Health Unit website.
