What is radon?

A natural gas from the soil that can enter homes through the foundation. You can't see or smell it, but a simple test tells you exactly where you stand.

Mitigation is always recommended

There is no known safe level of radon.

Reading (pCi/L)EPA (U.S.)WHORecommendation
Under 2.0under 74 Bq/m³ Below the EPA range for action Below WHO reference level Lower is still better. Mitigation can reduce it further. Retest every two years.
2.0 – 2.674 – 99 Bq/m³ EPA: consider fixing (2.0–3.9) Just under WHO reference level Mitigation recommended. Retest to confirm if the first test was short-term.
2.7 – 3.9100 – 147 Bq/m³ EPA: consider fixing (2.0–3.9) Above WHO reference level Mitigation recommended. Wingreen can walk you through the options.
4.0 and up148 Bq/m³ and up EPA action level: fix the home Above WHO reference level Mitigation strongly recommended. Most systems are installed in a day.
