Attention (June 1, 2026 - September 1, 2026): Summer Radon Testing

SUMMER RADON TESTING: 6-MONTH RADON TEST RECOMMENDED

Common practice states that winter is the optimal time for radon testing. 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. With this, you have three options:

Complete a 180-day (6-month) radon test now.
Wait until September and complete a radon test lasting 91+ days (3 months).
Test for an entire year.

Help us understand Canada’s radon problem

Our past and present Evict Radon National Study research participants have contributed to new ground-breaking research exposing Canada’s radon problem. Their contribution is helping us accomplish our mission to ‘evict’ radon from our homes and prevent future cases of radon-induced lung cancer.
