Thank you for your interest in testing with the Evict Radon National Study

The Evict Radon National Study is a national research study involving researchers and scientific partners from across Canada who are 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 our at-cost, research-grade radon test kits and enrolling in our national, public university-based research study, you are helping researchers from across Canada to understand radon exposure and develop new ways to protect ourselves and loved ones.

Common practice stated 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.

Your Results

IMPORTANT: The estimated risks below apply to otherwise healthy adults, and are expected to be different (likely higher) for babies, children, and teens, as well as persons experiencing other lung health concerns.

Your current radon exposure is estimated to be below where a statistically significant increase in lifetime relative risk of lung cancer is evident for a typical adult who does not smoke tobacco.

Your absorbed alpha radiation dose (to the lungs) from residential radon gas inhalation is 0 mSv/yr, with a total exposure of 0 mSv over the period you have lived in your current home(s).

You are below worldwide and national averages for radon inhalation exposure.

By living in your home(s) for 850 years, you will receive the equivalent dose of radiation from radon, as one CT scan to the abdomen, pelvis, spine, or heart


The blue in the chart above represents real radon exposure, as measured through people participating in the Evict Radon National Study. Yes, this means that there are Canadians experiencing higher radiation doses per year just from living in their homes, compared to an astronaut on the international space station.
