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.

Thank you for your participation in our research. Please reach out to [email protected] if you have any questions.
