National Action Level 4.0 pCi/L
This is a NATIONAL Action Level
- i.e. does not vary by state
- There is no mandate to test in single-family residential dwellings, yet.
There is No Safe Level of Radon Exposure
- WHO studies show radon risk as low as 2.7 pCi/L
- EPA also recommends that Americans consider fixing their home at radon levels between 2 pCi/L and 4 pCi/L
- EPA says most homes can reasonably achieve a level below 2.0 pCi/L and that should be our goal!
