Seasonal Testing Program
Frequently Asked Questions
Clear answers to common questions about how the Seasonal Testing Program works and what to expect.
Frequently Asked Questions
Why do I start with a short‑term test?
It gives a quick snapshot of your home’s radon level and helps determine the correct next step in the program.
Why do I need a long‑term or 90‑day test if my result is below 8.0 pCi/L?
Because radon levels change with the seasons. A season‑bridging test provides a more accurate picture of your home’s true annual radon level.
Is it safe to wait for the long‑term test?
Yes. Homes below 8.0 pCi/L do not require urgent action and waiting for a season‑bridging test improves accuracy.
If my test result is below 8 pCi/L can I get another short‑term test instead?
No. A second short‑term test would not improve accuracy. Season‑bridging tests are required for homes below 8.0 pCi/L.
What if my first test is 8.0 pCi/L or higher?
You will receive guidance and may request a second short‑term test to confirm the result before making decisions.
Do I have to mitigate if my long‑term test is high?
No. The program provides information and tools through Radon Navigator™ to help you make an informed decision about what’s right for your home and family.
