Attention (July 1st, 2025 - present): Update on Potential Canada Post Strike. 

The Canadian Union of Postal Workers (CUPW) has initiated strike action, including a nationwide overtime ban. On June 16th, CUPW members were asked to vote on Canada Post’s comprehensive offer to CUPW.

As this situation continues to evolve, the Evict Radon National Study continues to take precautionary steps to minimize disruptions caused by any interruptions in postal service. Radon test kits will continue to be shipped out until a potential strike has officially commenced. Return shipping may be affected, and we are recommending that participants continue to test until the situation is resolved. Read more about return shipping here.

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.
