What does this average radon level mean?
- The EPA recommends mitigation for homes or buildings that test at or above 4.0 pCi/L.
- The World Health Organization recommends fixing radon levels if results are 2.7 pCi/L (100 bq/m3) or higher.
- If you live or work in this area, you could be exposed to dangerous levels of radon gas.
- The only way to determine the radon level in YOUR home or building is to TEST.

Regardless of your results, we recommend follow-up testing.
Because radon is a naturally occurring gas that comes from the ground, levels can fluctuate with varying weather and seasonal conditions. If you test in the warm summer months, we recommend testing again in the winter. Radon levels often increase in the colder months due to pressure changes.
Follow-up testing is always a good option to be sure of your risk of radon exposure at home. Accurate and reliable results are the first place to start in making sure the air you breathe at home is healthy, safe, and clean.
