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. 

Understanding Your Radon Test Results

Your Report Will Indicate Your Radon Levels.

What do I do once I receive my results?

The Canadian guideline established by Health Canada for the maximum exposure limit of radon in your home is 200 Bq/m3. Your report will indicate your radon reading under the RADON RESULT column. We’ve included an example report for you to look at. This report will be emailed to you using the email you registered the device with.

How to interpret your results

How do I interpret my results?

If you do not understand or wish for clarification about your reading, please contact us at [email protected] 

NOTE: If you did not register the device properly, you will not receive your results from the lab. To ensure you did that correctly, visit this section.

Do I need to retest later on? 

Canadian National Radon Proficiency Program (C-NRPP) certified professionals recommend you retest for radon about every 5 years. However, unless you perform any major home renovation or anything else to change the air dynamics of the home, your radon level should stay the same.
