RADON TESTING APRIL - AUGUST?: 6 MONTH RADON TEST ENCOURAGED  

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. 

Radon Testing Period

How Long to Wait after Starting Your Radon Test.

Test for between 3 and 12 months.

Health Canada recommends that we all should test for radon for a minimum of 3 months. The amount of radon entering a building can fluctuate up and down quite a lot over a short period of time. This is normal and by having a long (90+ days or more) radon test, these fluctuates are averaged out, returning the real radon level of a house. 

Here are the three options used by most people:

  • A minimum period of 91-day test. A good time to start a test is from September to March.
  • If you are starting from April to August, perform a 6-month test.
  • Deploy your test for the entire year

The device is only active once you have opened the vacuum-sealed plastic bag it will arrive in. As soon as you open this vacuum-sealed bag, the test starts. The most important thing is to accurately record the start and end date of the test, via the registration process.
