Thank you for your interest in testing with Evict Radon

Evict Radon is a Canadian non-profit organization dedicated to solving Canada’s significant and worsening radon-gas exposure problem. Radon is a substantial cause of lung cancer even in non-smokers. By testing your home with one of our non-profit, research-grade radon test kits and enrolling in our national, public university-based research study, you are helping Evict Radon-aligned researchers from across Canada to understand radon exposure and develop new ways to protect ourselves and loved ones.

Common practice states that winter is the optimal time to radon test. However, as we collect more data, we have determined little difference between winter and spring radon testing. We do, however, encourage our participants to test over seasonal change. At this time, the best and most accurate radon readings obtained during the spring and summer months are those that are longer than 6 months. 

Where to place your device

Deciding where to place your device can sometimes be a difficult decision. The best thing is to not overthink it. You simply want to test the air you and your loved ones are regularly breathing within the home. 

As a general rule, place the device in the lowest level of your home that you or someone else spends about 4 or more hours a day.

This could be your basement, or perhaps the main floor. Do not place the radon test in kitchens, bathrooms, near open windows or other areas with fans or strong airflow. Bedside tables are a great place because we spend so much time breathing the air in our bedroom. Areas of the home that no-one spends time in (crawl spaces, furnace room, etc.) are also not ideal.

Optionally, there is a loop for hanging the device to help keep it safe and unharmed during the testing period. However, do not place them on the floor, or near the ceiling. You want to test the air you breathe.

In Canada, for properties with forced air ventilation (i.e. furnaces) we have documented a 13% decrease in radon when you move up from the basement to the main floor, but then no further decrease beyond that. This makes sense as the level of your property in direct contact with the ground will have the highest amount of radon. But if you never use your basement, don’t test there.
